Features and Benefits
• Time-delay coupled with Class CC current-limiting response
provides close sizing on small motor and relay circuits, and
maximum component short-circuit current rating protection.
• 200kA interrupting rating provides high ratings for control
circuit locations.
• Class CC rejection feature, with appropriate fuse block,
prevents inserting lesser-rated supplementary fuses.
• Inventory consolidation of 13⁄32 x 1 1⁄2 inch supplementary
fuses reduces SKU investment and minimizes potential for
misapplying fuse.
• Selective coordination ratio of 2:1 (within Low-Peak fuse
family) prevents electrical shutdowns from extending
beyond the failed circuit.

Medium Voltage Fuses

Medium Voltage Fuses
Worldwide Circuit Protection Solutions
Cooper Bussmann is a world-leading supplier of medium
voltage fuses. Each product is backed by an efficient
worldwide distribution network with unrivaled service and
technical support. Cooper Bussmann circuit protection
solutions comply with major international standards: ANSI,
BS, DIN, IEC and UL.
Fuse Types
Medium voltage fuses generally fit into two categories –
expulsion fuses and current limiting fuses. The definitions per
ANSI C37.40 are:

Expulsion Fuse: “A vented fuse in which the expulsion effect
of the gases produced by internal arcing, either alone or
aided by other mechanisms results in current interruption.”
Expulsion fuses will limit the duration of an overcurrent
event, but they will not limit the magnitude of fault current.
Cooper Bussmann offers two types of expulsion fuses:
replacement fuse links for fused cutouts and boric acid
fuses.

Current Limiting Fuse: “A fuse unit that, when in its currentresponsive element is melted by a current within the fuse’s
specified current-limiting range, abruptly introduces a high
resistance to reduce current magnitude and duration,
resulting in subsequent current interruption.” A current
limiting fuse will reduce the magnitude a fault current as well
as limit the duration of the overcurrent event when operating
in its current limiting range. Cooper Bussmann offers a broad
range of current limiting fuses for protection of feeders,
transformers and motor circuits designed to ANSI, BS, DIN
and IEC standards.
Medium Voltage Current Limiting Fuses
Current limiting fuses are classified into three categories:

1. Full Range – defined by ANSI C37.40 as “a fuse capable
of interrupting all currents from the maximum rated
interrupting current down to the minimum continuous current
that causes the melting of the fusible element(s), when the
fuse is applied at the maximum ambient temperature
specified by the manufacturer.” It is able to interrupt any
current that will melt its element.

72

2. General Purpose – defined by ANSI C37.40 as “a fuse
capable of interrupting all currents from the maximum rated
interrupting current down to the current that causes melting
of the fusible element(s) in one hour.” Not all currents fall
within this range. It is possible for the fuse to be exposed to
an overcurrent lower than the value given by the one hour
criteria. In that case, a different overcurrent protection device
would be required to interrupt the overcurrent.
3. Back-up – defined by ANSI C37.40 as “a fuse capable of
interrupting all currents from the maximum interrupting rating
current down to the minimum interrupting current.”
The minimum interrupting current is the lowest current that
the fuse will be able to clear properly. This creates a need to
place a low current interrupting device, such as motor
overloads, in series with the back-up rated fuse.
E- and R-Rated Fuses
In North America, current limiting fuses typically fall into the
category of E-Rated fuses and R-Rated fuses. Cooper
Bussmann also offers a wide range of current limiting fuses
designed to BS, DIN and IEC standards.

E-Rated fuses are used to protect feeder circuits, power
transformers and potential transformers. E-Rated fuses have
defined current response times specified by ANSI C37.46.
E-Rated fuses 100A and below must melt in 300sec at an
rms current within the range of 200% to 240% of the
continuous current rating. E-Rated fuses above 100A must
melt in 600sec at an rms current within the range of 240% to
264% of the continuous current rating of the fuse. Cooper
Bussmann offers a wide variety of full range and general
purpose E-Rated fuses from 2.4kV up to 38kV.

R-Rated fuses are back-up fuses that provide short-circuit
protection for motor circuits. They are applied with MV motor
starters which provide the overload protection for the circuit.
R-Rated fuses also have defined current response times
specified by ANSI C37.46. R-Rated fuses will melt in a range
of 15 – 35sec at a current equal to 100 times the “R” rating.
Cooper Bussmann offers 2.4kV, 5.08kV, 7.2kV and 8.3kV
R-Rated fuses for motor circuit protection.

Medium Voltage Fuses

British Standard Dimensioned IEC Fuses for
Motor Circuit Protection
The Cooper Bussmann range of motor fuses are designed to
meet the specific requirements necessary for motor
protection. During the starting cycle of direct on-line motors,
the fuse elements will reach a considerably higher
temperature than during normal operation; (this is due to the
high amount of current the motor will draw as it starts,
typically, six times its normal load current value). This results
in expansion and contraction of the fuse elements and could
cause premature operation of the fuse.
Medium
Voltage
Fuses

Cooper Bussmann motor fuses encompass an advanced
design to minimize this effect. This therefore, negates the
need to over specify the fuse rating due to high values of
motor starting current.
Cooper Bussmann motor fuses operate extremely quickly
under heavy fault currents, resulting from the time / current
characteristic. Low power dissipation ensures low
temperature rise, important in multi-tier starters for example.
Switching (arc), voltages are lower than permitted values,
therefore, 5.5kV fuses are also suitable for 4.8kV and
2.4kV circuits.

This Catalog Number selection table is based upon the following criteria:

1. Withstand against magnetizing inrush current taken as 12 times full-load current for 0.1 second.
2. Withstand against 150% permissible overload current. Recommendations marked with asterisks have the following significance:*Limited to permissible overloads of 130%.
**Permits use of a 12kV OHFMA 80A fuse with a 100kVA transformer where permissible overload does not exceed 130%.
3. For 6.6kV systems, 12kV fuses are recommended where possible in the interests of standardization.
4. Wherever possible, 10 inch long FO1 fuses are offered rather than equivalent 14 inch FO2 types.
5. The above recommendations are not generally applicable to transformers feeding motor circuits with starting currents in excess of the transformer full load current. In this event, please consult
Cooper Bussmann.

Medium Voltage Fuses

BBU Boric Acid Fuses
BBU

is designed to operate. Its
dielectric withstand level
corresponds to insulation levels
of power class equipment, thus
the name “power fuse.”
Maximum voltage ratings for
BBU fuses are: 17kV, 27kV and
38kV.
Amps:— The continuous amp rating of a
BBU fuse should equal or
exceed the maximum load
current where the fuse is
applied. They are designed to
carry their rated continuous
current without exceeding the
temperature rise outlined in
NEMA and ANSI standards. The
BBU is available with
continuous current ratings up to
200 amps The current ratings
carry an “E” designation as
defined by ANSI and NEMA.
For example, the current
responsive element rated 100E
amps or below will melt in 300
seconds at an RMS current
within the range of 200 to 240
percent of the continuous
current ratings. Above 100E
amps, melting takes place in
600 seconds at an RMS current
within the range of 220 to 264
percent of the continuous
current rating.
IR:—
BBU fuses have interrupting
capabilities from 10kA to 14kA
symmetrical.
Features and Benefits
• Voltage ratings of up to 38kV coupled
with ratings to 200A provide a wide
range of circuit protection.
• Time-current characteristics allow for
easier coordination with downstream
devices.
• Provides replacement of a variety of
existing systems.
Typical Applications
• Power and Distribution Transformer
Protection
• Medium Voltage Feeder Circuit

Application Notes
Low currents, usually referred to as overload currents, must
be considered as BBU fuses have a rather low thermal
capacity. They cannot carry overloads of the same
magnitude/duration as motors and transformers of equal
continuous currents. For this reason, the BBU fuse must be
sized with the full load current in mind so the fuse does not
open on otherwise acceptable overloads and inrush
conditions. Coordination should be considered to help
determine what type of fuse is applied. The BBU fuse
interrupts at a natural current zero in the current wave and
allows a minimum of a half-cycle of fault current to flow
before the fault is cleared. The time-current characteristics
associated with a BBU fuse has a rather gradual slope
making it easier to coordinate with downstream equipment.
In addition, the BBU is ideal for higher voltage (up to 38kV)
and high current applications (up to 200A). It is important to
examine the minimum melting and total clearing time-current
characteristics of this fuse.

A asymmetrical current
B symmetrical current
Parallel Connection
When fuses are connected in parallel it is recommended that
the applied voltage does not exceed 0.9 UN (the rated
voltage of the fuse). This is due to the fact that the energy
released within the fuses may be unevenly shared between
the parallel connected barrels.
When fuses are connected in parallel, one must take into
account that the current sharing is not necessarily equal. And
it must be checked, that the maximum load current is not
exceeded.

Fuses in series may not equally divide the applied voltage. It
is recommended that series connected fuses should only be
operated at fault currents that yield melting times less than
10 ms and a recovery voltage per fuse of less than or equal
to 0.9 UN (the rated voltage of the fuse).
Mounting Guidance
The recommendations below have to be followed when
mounting a Cooper Bussmann fuse with end plate threaded
holes.
1. Screw in studs: 5 N•m Max, 3 N•m Min
2. Attachment of the fuse to bussbar by means of nut and

Overloads
The design of Cooper Bussmann® fuses is such that they
can be operated under rather severe operating conditions
imposed by overloads (any load current in excess of the
maximum permissible load current).
In applications, there will be a maximum overload current,
Imax, which can be imposed on the fuse with a
corresponding duration and frequency of occurrence.
Time durations fall into two categories:
1. Overloads longer than one second
2. Overloads less than one second termed “impulse” loads.
The following table gives general application guidelines
which, in the expression Imax < (% factor) x It. It is the

When impulse loads are an intrinsic/normal parameter of the
load current either as single pulse or in trains of pulses or
when their level is higher than the melting current at 0.01
seconds (per time-current curve), contact Cooper Bussmann
for application assistance.
In addition to the parameters set forth in the preceding table,
the RMS value of the load current as calculated for any
period of 10 minutes or more should not exceed the
maximum permissible load current.
Furthermore, it is important that a fuse should not be applied
in the non-continuous/dashed portion of the associated
time-current curve.
Any time-current combination point which falls in the
non-continuous/dashed portion of the time-current curve is
beyond the capability of the fuse to operate properly.
DC Operation
Depending upon the short-circuit time constant and the
magnitude of the prospective short-circuit current, the dc
voltage at which a fuse can be applied may be less than its
ac rating. Long time constants require a lower dc voltage.
Conversely, however, higher available prospective shortcircuit currents result in faster fuse openings and thus permit
a fuse to be operated at a higher DC voltage.
Consult Cooper
Bussmann for additional
information and application assistance when
fuses have to operate
under DC conditions.

Square Body Applications
Maximum Permissible Load Current

Temperature Correction Curve

The rated current value of Cooper Bussmann fuses is based
on the ambient temperature in the space immediately below
the fuse of 20°C. The following graph gives correction factors
(k) for a range of temperatures (–40°C to +80°C). Maximum
permissible continuous load currents can be calculated by
applying the following formula:

The maximum permissible continuous load current Ib of a
fuse can be checked empirically (i.e., by satisfying the
formula below) by making simple voltage and temperature
measurements under actual operating conditions after the
fuse has been installed in its operating location and loaded
at the calculated Ib value:
E2

Application Procedure
Step

Procedure

(1) Select a short-blade fuse to permit
mounting of microswitch 170H0069

1.1 Taking into consideration only the
continuous load current and ambient
temperature, from Table on page 127
tentatively select fuse 170M3669
400A, 690V).

Remarks

—

(2) Determine I2 t (total clearing) at 440V.

2.1 See Table, page 127. Note I2t is
105,000A2s at rated voltage of 690V.
2.2 From the figure on page 126, note that
OK
correction factor K = 0.65.
2.3 I2t660V ≈ K = I2t440V
105,000 ≈ 0.65 = 68,250

(3) Determine maximum arc voltage
at 440V

3.1 From the figure on page 126, note that
OK
maximum voltage at 440V is 900V

(4) Determine maximum permissible
continuous load current Ib.

4.1 Per page 115 data,
Ib = In ≈ k ≈ (1 + 0.05V) ≈ Kb
Ib = 400A ≈ 0.8 ≈ (1 + 0) ≈ 1
Ib = 320A

(5) Plot a “line profile” showing the
expected load and overload currents.
Determine that overload and impulse
load currents do not exceed their
maximum permissible values.

5.0 Calculate Imax per Table,
High Speed Fuse Application Guide
page 16, for each overload and impulse
load.

Current In Amperes

Calculation of Watt Loss
From the Table on page 127, watt loss at 400 amps is 60
watts. The continuous load current of 300A is 75% of rated
current (400A). From page 126, the correction factor
Kp = 0.5.
Watt Loss 75% = Watt Loss 100% ≈ Kp
= 60W ≈ 0.5
= 30 watts

Other high speed fuses are available from Cooper
Bussmann with voltage ratings of 380 to 10,000V and current
ratings up to 10,000A in a single unit configuration. Fuses
can be supplied with open fuse, “pin” indicators. Various
types of microswitches are also available (see page 185).

The tentatively selected fuse 170M3669 with microswitch 170H0069 meets all application parameters; no further
selection would be necessary.

Rated Current
The rated current of this fuse range has been given with
copper conductors that have a current density of 1.3 A/mm2
(IEC 60269-4). For conductor cross section according to IEC
60269-1, the fuses with a rated current higher than 125A
must be derated. Please contact Cooper Bussmann for
application assistance.

Square Body US Style — 690V/700V (IEC):
40-2000A
690V/700V (IEC) 40-2000A

Arc Voltage
This curve gives the peak
arc voltage, UL, which
may appear across the
fuse during its operation
as a function of the
applied working voltage,
Eg, (rms) at a power factor
of 15%.

Specifications
Description: Square body US
style high speed fuses.
Dimensions: See dimensions
illustration.
Ratings:
Volts: — 690Vac (IEC)
— 700Vac (UL)
Amps: — 40-200A
IR: — 200kA RMS Sym.
Agency Information: CE, Designed and tested to IEC
60269: Part 4, UL Recognized. Consult Cooper Bussmann
for UL Recognition/ CSA Component Acceptance status.

Power Losses
Watts loss at rated current
is given in the electrical
characteristics. The curve
allows the calculation of
the power losses at load
currents lower than the
rated current. The
correction factor, Kp, is
given as a function of the
RMS load current, Ib, in %
of the rated current.

50-1400A
1250V/1300V (IEC/UL) 50-1400A

Arc Voltage
This curve gives the peak
arc voltage, UL, which
may appear across the
fuse during its operation
as a function of the
applied working voltage,
Eg, (rms) at a power factor
of 15%.

Specifications
Description: Square body flush
end contact high speed fuses.
Dimensions: See dimensions
illustrations.
Ratings:
Volts: — 1250Vac (IEC)
— 1300Vac (UL)
Amps: — 50-1400A
IR: — 100kA RMS Sym.
Agency Information: CE, Designed and tested to IEC
60269: Part 4, UL Recognized. Consult Cooper Bussmann
for UL Recognition/CSA Component Acceptance status.

The total clearing I2t at rated
voltage and at power factor
of 15% are given in the
electrical characteristics. For
other voltages, the clearing
I2t is found by multiplying by
correction factor, K, given as
a function of applied working
voltage, Eg, (rms).

Watts loss at rated current
is given in the electrical
characteristics. The curve
allows the calculation of
the power losses at load
currents lower than the
rated current. The
correction factor, Kp, is
given as a function of the
RMS load current, Ib, in %
of the rated current.

Designed and tested to:
• BS 88: Part 4
• IEC 269: Part 4
• UL Recognized
Cooper Bussmann offers the industry’s widest range of
British style semiconductor fuses and accessories.
Cooper Bussmann British style products use innovative arc
quenching techniques and high grade materials to provide:
• Minimal energy let-through (I2t)
• Excellent DC performance
• Good surge withstand profile
British style fuses are typically found in equipment
manufactured in the United Kingdom or British
Commonwealth countries. However, North American
manufacturers have begun to specify British style fuses —
particularly in UPS applications at 240V or less — to take
advantage of their size, performance and cost benefits.
Voltage Rating
All Cooper Bussmann British style fuses are tested to IEC
269: Part 4. This standard requires a test voltage which is 5%
higher than the rated voltage. In North America, fuses are
required to clear only their rated voltage.
Accessories
Trip-indicator fuses are available for use in parallel with the
main fuse. Indicator fuses can be attached to the associated
fuselink, or mounted separately in panel-mounted fuseclips.
In addition, a push-on adapter and microswitch attachment
are available, to provide remote indication. Fuse blocks are
also available for most applications.

Trip-Indicators

CL1 Panel mount fuse clips
are available for mounting a
trip-indicator when mounting
directly on the fuse is
impractical. Order part
number CL1.

Trip-indicators are available for use in parallel with the
main fuse. They can either be attached to the associated
fuse or mounted separately in panel mounted fuse clips,
reference CL1. A push-on adapter and microswitch
attachment is available for use with the trip indicator to
give the facility of remote indication, reference MAI.
Fuse ratings of 20A and below cannot usually
accommodate a trip-indicator.

Supplementary ranges cover applications up to 660Vac and
500Vdc including those with nonstandard tag fixings.
Cooper Bussmann fuses are manufactured under quality
systems independently assessed to BS 5750 (ISO 9002) and
appropriate ratings carry the ASTA 20 endorsement.
Selecting fuses is relatively simple and effective. The
following notes cover the majority of applications. For further
information contact our Application Engineers at
636-527-1270.
Circuit Loading
The current rating of the fuse should not be less than the full
load current of the circuit. The circuit should be so designed
that small overloads of long duration will not be of frequent
occurrence.
Cable Ratings & Protection
There is an increasing move away from 70°C PVC insulation
to materials that are more environmentally friendly, for
example 90°C XLPE. The ratings of fusegear, switches,
accessories, etc. are generally based upon the equipment
being connected to conductors intended to be operated at a
temperature not exceeding 70°C in normal service.
In view of the above, it is recommended that the practice of
designs based upon conductor temperatures of 70°C be
regarded as the norm. The equipment manufacturer should
be consulted to ascertain the reduction of nominal current
rating of the equipment if conductor temperatures exceeding
70°C are used. In addition, an overriding factor is often
voltage drop.
Fuses with gG characteristics protect associated cables
against both overload and short-circuit current, provided that
the current rating of the fuse 1N is equal or less than the
current carrying capacity of the cable 1z.
In motor circuits, the motor starter will provide the overload
protection and the fuses will provide the short-circuit
protection. The maximum fuse size that can be used
depends upon the type of cable used and is determined
using the appropriate K factor. The following table gives the
maximum sizes of fuses that are recommended for two
popular cables with copper conductors, 70°C PVC (K = 115)
and 90°C thermosetting (K = 143).

The standard range of fuses for low voltage industrial and
general purpose applications meet the requirements of
BS 88 and IEC 60269. By using advanced fuse technology,
current ratings up to 400A have compact dimensions, but
retain standard dimensional and performance requirements.
These designs are for 315/240V systems. The standard
range of fuses are available from 2-1250A in the following
tag forms: Offset Blade - Offset Bolted - Center Bolted.

Ambient Temperature
The derating, in terms of current, of 0.5% per °C above an
ambient of 35°C is recommended.

Capacitor Circuits
For power factor correction in capacitor circuits, the fuse
should be chosen with a current rating greater than 1.5 times
the rated capacitor current. This takes into account the high
inrush current, circuit harmonics and capacitor tolerances.
Motor Circuits
In motor circuits, the fuse has to withstand the motor's
starting current and often requires a higher rating than the
motor's full load current. Coordination recommendations are
made by the manufacturers of motor starters in accordance
with IEC 60947-4-1. To get Type 2 coordination with fuses,
tests are performed with the latest gG or gM fuses to BS 88
or IEC 60269 that have pre-arcing I2t values towards the
bottom of specified limits. This means that Cooper
Bussmann fuses are suitable to provide Type 2 coordination.
Extended dual ratings of motor circuit protection fuses with
gM characteristics are available in most popular fuse sizes to
extend the use of associated equipment with appropriate
economies. In the majority of applications, gG fuses are
used. It is not essential to use gM fuses for motor circuit
protection, they simply extend the utilization of standard
equipment.
Below is a table of recommended fuses at 415V. In most
applications, the run-up time is less than 5 seconds and duty
is infrequent - no more than twice per hour. The next larger
rating should be used for more demanding applications.

Interrupting Rating
The standardized interrupting rating values are 80kA for
voltages of 415Vac and above, and 40kA for DC
applications. The 240Vac designs have an interrupting rating
of 50kA.
Coordination Ratio
All fuses to BS 88 Parts 2 and 6 will give a coordination ratio
of 2:1; and for most practical situations a ratio of 1.6:1 (two
steps in the R10 series). Example: an upstream fuse rated at
160A will coordinate with a downstream fuse rated at 100A.
Current and Energy Limitation
The range of fuses have pre-arcing I2t values towards the
bottom limits of BS 88 Parts 2 and 6. This ensures excellent
current and energy limitation. They also have lower power
losses at rated current. This assists in the appropriate
interchangeability with other makes of fuses.
Transformers
When fuses are used on the primary side of transformers,
the normal fuse current rating should be at least twice the
nominal transformer primary current.
Fluorescent Lighting
The normal fuse current rating should be at least twice the
normal full load current of the maximum number of lights to
be simultaneously switched.

Quik-Spec™ Power Module — All-in-one Elevator Disconnect
Hydraulic Elevators
Hydraulic elevators need battery backup to help prevent
stranding passengers. To keep the elevator from moving
when it’s been manually shut down for maintenance, the
NEC® requires battery backup be connected to the elevator
disconnecting means through an auxillary contact.
However, an unintended consequence can be passengers
getting stranded because of devices that open
automatically (circuit breakers and disconnects utilizing a

molded case switch with a trailing fuse block) will operate
with a fault on their loadside. That operation also disables
the battery backup and strands passengers. That’s why the
Power Module has a non-automatic fusible shunt trip
switch. If the Power Module has a fault on its loadside, the
fuses open and the battery stays enabled. Thus the Power
Module ensures that battery power is enabled when the
passengers need it to exit - and disabled to allow safe
maintenance of the elevator and hoistway.

Reason
Need to lower elevator to allow passengers to exit.
Recall is initiated by smoke detector and lowers elevator to
a safe floor. Battery not needed.
Worker to perform maintenance. Elevator must remain
stationary to prevent injury.
Need to lower elevator to allow passengers to exit.

Selection Table for SCCR Power Distribution Blocks and
Power Terminal Blocks
Short-Circuit Current Rated Power Distribution
Blocks
Cooper Bussmann offers three distinctly different styles of
short-circuit current rated power distribution blocks (PDBs)
and power terminal blocks (PTBs) to match different
application needs. The differences are whether the power
distribution blocks are enclosed or not, and whether they are
UL1953 Listed PDBs or UL1059 Recognized PTBs, which
have different minimum spacing requirements. The table on
this page can assist in the selection of the right series for
your application requirements.

Control Panels. Marking the SCCR on Industrial Control
Panels (NEC® 409.110), Industrial Machinery Electrical
Panels (NEC® 607.3(A)), and HVAC equipment (NEC®
440.4(B)) is now required by the National Electrical Code.
PDBs or PTBs not marked with a SCCR, typically are the
weakest link and may limit an assembly to no more than 10kA
SCCR. The PDBFS and PDB Series have increased spacing
required where used in feeder circuits in equipment listed to
UL508A (UL1059 PTBs must be evaluated for proper spacings). Also, for building wiring systems, the PDBFS Series
and PDB Series power distribution blocks can be used to
meet the new 2008 NEC® requirements in section 376.56(B)
for PDBs in wireways.

Why these are important?
Assembly short-circuit current ratings (SCCRs) are now
required in the 2008 NEC® and UL 508A Listed Industrial

TPM Alarm Schematic

NOTES:
1. The resistance, R, must be provided by the end-user to
limit the alarm output current to a maximum of 20mA. The
value, R, should be calculated using the system voltage
value.
• If remote alarm functionality is not required, the END-USER
CIRCUITRY must still be supplied to provide a resistive path
to the return for the local alarm to properly function.
2. The fuse is polarized to maintain proper orientation with
the switch housing. The line and load terminals are identified
on the switch housing.

Application Notes
• The line connection uses a 1⁄4-20 bolt (metric – M6X1) that
threads into the line terminal. The line terminal is designed
with a float of ±0.02” (± 0.50mm) to allow for variation in the
distance between the TP158HC mounting flange and the
line busbar (see Dimensions). Equipment should be
designed to eliminate any relative movement between the
TP158HC mounting flange and the line busbar.
• The alarm circuit is not intended for precharging of
capacitive circuits. Alarm circuit current 1A maximum.

Easy Fuse Replacement

Features and Benefits
• Similar profile, mounting method, and backplane
configuration as 15800 Series. The TP158HC can be
installed into existing 15800 Series panels using the space
of two 15800 disconnects
• Innovative new fuse pullout design eliminates need for
tools to replace the Telpower type TPL-B fuse
• Alarm output with wire wrap terminal or connection to
0.063 inch (1.6mm) thick common alarm bus

Adapters for DIN and American Rails
Specifications
Description: Cooper
Bussmann® DIN rail
adapters permit secure,
positive snap-on mounting
of Cooper Bussmann 0-30A
fuse blocks (one-, two-, or
three-pole) onto various
size rails to eliminate
costly and time consuming
drilling, tapping, and screw
mounting. Adapters
mechanically lock into
mounting holes of fuse blocks in
seconds to become an integral part of the block.
One adapter is required for one- and two-pole Cooper
Bussmann blocks. Two adapters are required for three-pole
blocks.
With the exception of the 32mm DIN rail, all blocks with
adapters can be removed from a rail simply by pulling up its
release tab.
Use of rail end-stops on both sides of adapters is
recommended.
Construction: Molded from “Lexan™ 241” for high strength
and flexibility.

Fuse Technology
Circuit Protection
The following is a basic introduction to overcurrent protection
and fuse technology. In depth information on the selection and
application of overcurrent protective devices is available in the
Cooper Bussmann publication “Selecting Protective Devices”
(SPD). This publication is available free of charge as a PDF
download at www.cooperbussmann.com/spd.
Electrical distribution systems are often quite complicated.
They cannot be absolutely fail-safe. Circuits are subject to
destructive overcurrents. Harsh environments, general
deterioration, accidental damage, damage from natural
causes, excessive expansion, and/or overloading of the
electrical distribution system are factors which contribute to the
occurrence of such overcurrents. Reliable protective devices
prevent or minimize costly damage to transformers,
conductors, motors, and the other many components and
loads that make up the complete distribution system. Reliable
circuit protection is essential to avoid the severe monetary
losses which can result from power blackouts and prolonged
downtime of facilities. It is the need for reliable protection,
safety, and freedom from fire hazards that has made the fuse a
widely used protective device.
Overcurrents
An overcurrent is either an overload current or a short-circuit
current. The overload current is an excessive current relative to
normal operating current, but one which is confined to the
normal conductive paths provided by the conductors and other
components and loads of the distribution system. As the name
implies, a short-circuit current is one which flows outside the
normal conducting paths.

than the normal operating current. A high level fault may be
50,000A (or larger). If not cut off within a matter of a few
thousandths of a second, damage and destruction can become
rampant—there can be severe insulation damage, melting of
conductors, vaporization of metal, ionization of gases, arcing,
and fires. Simultaneously, high level short-circuit currents can
develop huge magnetic-field stresses. The magnetic forces
between bus bars and other conductors can be many hundreds of pounds per linear foot; even heavy bracing may not
be adequate to keep them from being warped or distorted
beyond repair.
Fuses
The fuse is a reliable overcurrent protective device. A “fusible”
link or links encapsulated in a tube and connected to contact
terminals comprise the fundamental elements of the basic
fuse. Electrical resistance of the link is so low that it simply
acts as a conductor. However, when destructive currents occur,
the link very quickly melts and opens the circuit to protect
conductors, and other circuit components and loads. Fuse
characteristics are stable. Fuses do not require periodic
maintenance or testing. Fuses have three unique performance
characteristics:
1. Modern fuses have an extremely “high interrupting rating”—can
withstand very high fault currents without rupturing.
2. Properly applied, fuses prevent “blackouts.” Only the fuse nearest a fault
opens without upstream fuses (feeders or mains) being affected—fuses
thus provide “selective coordination.” (These terms are precisely defined
in subsequent pages.)
3. Fuses provide optimum component protection by keeping fault currents
to a low value…They are said to be “current limiting.”

Overloads

Voltage Rating

Overloads are most often between one and six times the
normal current level. Usually, they are caused by harmless
temporary surge currents that occur when motors are
started-up or transformers are energized. Such overload
currents, or transients, are normal occurrences. Since they are
of brief duration, any temperature rise is trivial and has no
harmful effect on the circuit components. (It is important that
protective devices do not react to them.)

The voltage rating of a fuse must be at least equal to or
greater than the circuit voltage. It can be higher but never
lower. For instance, a 600V fuse can be used in a 208V circuit.

Continuous overloads can result from defective motors (such
as worn motor bearings), overloaded equipment, or too many
loads on one circuit. Such sustained overloads are destructive
and must be cut off by protective devices before they damage
the distribution system or system loads. However, since they
are of relatively low magnitude compared to short-circuit
currents, removal of the overload current within minutes will
generally prevent equipment damage. A sustained overload
current results in overheating of conductors and other
components and will cause deterioration of insulation, which
may eventually result in severe damage and short-circuits if not
interrupted.
Short-Circuits
Whereas overload currents occur at rather modest levels, the
short-circuit or fault current can be many hundred times larger

424

The voltage rating of a fuse is a function of its capability to
open a circuit under an overcurrent condition. Specifically, the
voltage rating determines the ability of the fuse to suppress the
internal arcing that occurs after a fuse link melts and an arc is
produced. If a fuse is used with a voltage rating lower than the
circuit voltage, arc suppression will be impaired and, under
some fault current conditions, the fuse may not clear the
overcurrent safely. Special consideration is necessary for
semiconductor fuse and medium voltage fuse applications,
where a fuse of a certain voltage rating is used on a lower
voltage circuit.
Amp Rating
Every fuse has a specific amp rating. In selecting the amp
rating of a fuse, consideration must be given to the type of load
and code requirements. The amp rating of a fuse normally
should not exceed the current carrying capacity of the circuit.
For instance, if a conductor is rated to carry 20A, a 20A fuse is
the largest that should be used. However, there are some
specific circumstances in which the amp rating is permitted to
be greater than the current carrying capacity of the circuit.

Application Guide

Fuse Technology
A typical example is the motor circuit; dual-element fuses
generally are permitted to be sized up to 175% and non-timedelay fuses up to 300% of the motor full-load amps. As a rule,
the amp rating of a fuse and switch combination should be
selected at 125% of the continuous load current (this usually
corresponds to the circuit capacity, which is also selected at
125% of the load current). There are exceptions, such as when
the fuse-switch combination is approved for continuous
operation at 100% of its rating.
Interrupting Rating
A protective device must be able to withstand the destructive
energy of short-circuit currents. If a fault current exceeds the
capability of the protective device, the device may actually
rupture, causing additional damage. Thus, it is important when
applying a fuse or circuit breaker to use one which can sustain
the largest potential short-circuit currents. The rating which
defines the capacity of a protective device to maintain its
integrity when reacting to fault currents is termed its
“interrupting rating”. The interrupting rating of most branchcircuit, molded case, circuit breakers typically used in
residential service entrance panels is 10,000A. (Please note
that a molded case circuit breaker’s interrupting capacity will
typically be lower than its interrupting rating.) Larger, more
expensive circuit breakers may have interrupting ratings of
14,000A or higher. In contrast, most modern, current-limiting
fuses have an interrupting rating of 200,000 or 300,000A and
are commonly used to protect the lower rated circuit breakers.
The National Electrical Code, Section 110-9, requires
equipment intended to break current at fault levels to have an
interrupting rating sufficient for the current that must be
interrupted.
Selective Coordination – Prevention of Blackouts
The coordination of protective devices prevents system power
outages or blackouts caused by overcurrent conditions. When
only the protective device nearest a faulted circuit opens and
larger upstream fuses remain closed, the protective devices
are “selectively” coordinated (they discriminate). The word
“selective” is used to denote total coordination…isolation of a
faulted circuit by the opening of only the localized protective
device.

A current-limiting fuse has such a high speed of response that
it cuts off a short-circuit long before it can build up to its full
peak value.
If a protective device cuts off a short-circuit current in less than
one-quarter cycle, before it reaches its total available (and
highly destructive) value, the device is a “current-limiting”
device. Most modern fuses are current-limiting. They restrict
fault currents to such low values that a high degree of
protection is given to circuit components against even very
high short-circuit currents. They permit breakers with lower
interrupting ratings to be used. They can reduce bracing of bus
structures. They minimize the need of other components to
have high short-circuit current “withstand” ratings. If not limited,
short-circuit currents can reach levels of 30,000 or 40,000A or
higher in the first half cycle (.008 seconds, 60Hz) after the start
of a short-circuit. The heat that can be produced in circuit
components by the immense energy of short-circuit currents
can cause severe insulation damage or even explosion. At the
same time, huge magnetic forces developed between
conductors can crack insulators and distort and destroy
bracing structures. Thus, it is important that a protective device
limit fault currents before they reach their full potential level.

Unlike electromechanical inertial devices (circuit breakers), it is
a simple matter to selectively coordinate fuses of modern
design. By maintaining a minimum ratio of fuse-amp ratings
between an upstream and downstream fuse, selective
coordination is assured.

Fuse Technology
Operating Principles of Cooper Bussmann® Fuses
The principles of operation of the modern, current-limiting
fuses are covered in the following paragraphs.
Non-Time-Delay Fuses
The basic component of a fuse is the link. Depending upon the
amp rating of the fuse, the single-element fuse may have one
or more links. They are electrically connected to the end
blades (or ferrules) (see Figure 1) and enclosed in a tube or
cartridge surrounded by an arc quenching filler material.
Cooper Bussmann® Limitron® and T-Tron® fuses are both
single-element fuses.
Under normal operation, when the fuse is operating at or near
its amp rating, it simply functions as a conductor. However, as
illustrated in Figure 2, if an overload current occurs and
persists for more than a short interval of time, the temperature
of the link eventually reaches a level which causes a restricted
segment of the link to melt. As a result, a gap is formed and an
electric arc established. However, as the arc causes the link
metal to burn back, the gap becomes progressively larger.
Electrical resistance of the arc eventually reaches such a high
level that the arc cannot be sustained and is extinguished. The
fuse will have then completely cut off all current flow in the
circuit. Suppression or quenching of the arc is accelerated by
the filler material. (See Figure 3.)
Single-element fuses of present day design have a very high
speed of response to overcurrents. They provide excellent
short-circuit component protection. However, temporary,
harmless overloads or surge currents may cause nuisance
openings unless these fuses are oversized. They are best
used, therefore, in circuits not subject to heavy transient surge
currents and the temporary over-load of circuits with inductive
loads such as motors, transformers, solenoids, etc. Because
single-element, fast-acting fuses such as Limitron and
T-Tron fuses have a high speed of response to short-circuit
currents, they are particularly suited for the protection of circuit
breakers with low interrupting ratings.
Whereas an overload current normally falls between one and
six times normal current, short-circuit currents are quite high.
The fuse may be subjected to short-circuit currents of 30,000
or 40kA or higher. Response of current limiting fuses to such
currents is extremely fast. The restricted sections of the fuse
link will simultaneously melt (within a matter of two or threethousandths of a second in the event of a high-level fault
current).
The high total resistance of the multiple arcs, together with the
quenching effects of the filler particles, results in rapid arc
suppression and clearing of the circuit. (Refer to Figures 4 & 5)
Short-circuit current is cut off in less than a half-cycle, long
before the short-circuit current can reach its full value (fuse
operating in its current limiting range).

Fuse Technology
Cooper Bussmann® Dual-Element Fuses
There are many advantages to using these fuses. Unlike single-element fuses, the Cooper Bussmann® dual-element, time-delay fuses can be sized closer to provide both
high performance short-circuit protection and reliable overload protection in circuits subject to temporary overloads and surge currents. For ac motor loads, a single-element
fuse may need to be sized at 300% of an a.c. motor current in order to hold the starting current. However, dual-element, time delay fuses can be sized much closer to motor
loads. For instance, it is generally possible to size Fusetron Dual-Element Fuses, FRS-R and FRN-R and Low-Peak® Dual-Element Fuses, LPS-RK_SP and LPN-RK_SP, at
125% and 130% of motor full load current, respectively. Generally, the Low-Peak Dual-Element Fuses, LPJ_SP, and CUBEFuse®, TCF, can be sized at 150% of motor full
load amps. This closer fuse sizing may provide many advantages such as: (1) smaller fuse and block, holder or disconnect amp rating and physical size, (2) lower cost due
to lower amp rated devices and possibly smaller required panel space, (3) better short-circuit protection – less short-circuit current let-through energy, and (4) potential
reduction in the arc-flash hazard.

Overcurrent protection must be reliable and sure. Whether it is the first day of the electrical system or thirty or more years later, it is important that overcurrent protective
devices perform under overload or short-circuit conditions as intended. Modern current-limiting fuses operate by very simple, reliable principles.

Application
Guide

When the short-circuit current is in the current-limiting range of a fuse, it is not possible for the full available short-circuit current to flow through the fuse – it’s a matter of
physics. The small restricted portions of the short-circuit element quickly vaporize and the filler material assists in forcing the current to zero. The fuse is able to “limit” the
short-circuit current.

Application Guide

Fuse Technology
Fuse Time-Current Curves
When a low level overcurrent occurs, a long interval of time will
be required for a fuse to open (melt) and clear the fault. On the
other hand, if the overcurrent is large, the fuse will open very
quickly. The opening time is a function of the magnitude of the
level of overcurrent. Overcurrent levels and the corresponding
intervals of opening times are logarithmically plotted in graph
form as shown to the right. Levels of overcurrent are scaled on
the horizontal axis; time intervals on the vertical axis. The
curve is thus called a “time-current” curve.

400
300

This particular plot reflects the characteristics of a 200A, 250V,
Low-Peak® dual-element fuse. Note that at the 1,000A
overload level, the time interval which is required for the fuse
to open is 10 seconds. Yet, at approximately the 2,200A
overcurrent level, the opening (melt) time of a fuse is only 0.01
seconds. It is apparent that the time intervals become shorter
as the overcurrent levels become larger. This relationship is
termed an inverse time-to-current characteristic. Time-current
curves are published or are available on most commonly used
fuses showing “minimum melt,” “average melt” and/or “total
clear” characteristics. Although upstream and downstream
fuses are easily coordinated by adhering to simple amp ratios,
these time-current curves permit close or critical analysis of
coordination.

The derating of dual-element fuses based on increased
ambient temperatures closely parallels the derating curve of
motors in elevated ambient. This unique feature allows for
optimum protection of motors, even in high temperatures.

Fuse Technology
Better Protection Against Motor Single Phasing
When secondary single-phasing occurs, the current in the
remaining phases increases to approximately 200% rated full
load current. (Theoretically 173%, but change in efficiency and
power factor make it about 200%.) When primary singlephasing occurs, unbalanced voltages occur on the motor circuit
causing currents to rise to 115%, and 230% of normal running
currents in delta-wye systems.
Dual-element fuses sized for motor running overload protection
will help to protect motors against the possible damages of
single-phasing.
Classes of Fuses
Safety is the industry mandate. However, proper selection,
overall functional performance and reliability of a product are
factors which are not within the basic scope of listing agency
activities. In order to develop its safety test procedures, listing
agencies develop basic performance and physical
specifications or standards for a product. In the case of fuses,
these standards have culminated in the establishment of
distinct classes of low-voltage (600V or less) fuses; Classes
RK1, RK5, G, L, T, J, H and CC being the more important.
The fact that a particular type of fuse has, for instance, a
classification of RK1, does not signify that it has the identical
function or performance characteristics as other RK1 fuses. In
fact, the Limitron® non-time-delay fuse and the Low-Peak
dual-element, time-delay fuse are both classified as RK1.
Substantial differences in these two RK1 fuses usually requires
considerable difference in sizing. Dimensional specifications of
each class of fuse does serve as a uniform standard.

In the above illustration, a grooved ring in one ferrule provides
the rejection feature of the Class R fuse in contrast to the
lower interrupting rating, non-rejection type.
Branch-Circuit Listed Fuses
Branch-circuit listed fuses are designed to prevent the
installation of fuses that cannot provide a comparable level of
protection to equipment.
The characteristics of Branch-circuit fuses are:
1. They must have a minimum interrupting rating of 10kA
2. They must have a minimum voltage rating of 125V.
3. They must be size rejecting such that a fuse of a lower
voltage rating cannot be installed in the circuit.
4. They must be size rejecting such that a fuse with a current
rating higher than the fuse holder rating cannot be installed.

Class R Fuses

For product data sheets, visit www.cooperbussmann.com/datasheets/ulcsa

Services &
Application
Guide

Class R (“R” for rejection) fuses are high performance,1⁄10 to
600A units, 250V and 600V, having a high degree of current
limitation and a short-circuit interrupting rating of up to 300kA
(RMS Sym.). Cooper Bussmann® Class R fuses include Class
RK1 Low-Peak® and Limitron® fuses, and RK5 Fusetron fuses.
They have replaced the K1 Low-Peak and Limitron fuses and
K5 Fusetron fuses. These fuses are identical, with the
exception of a modification in the mounting configuration called
a “rejection feature.” This feature permits Class R fuses to be
mounted in rejection type fuseclips. “R” type fuseclips prevent
older type Class H, ONE-TIME and RENEWABLE fuses from
being installed. The use of Class R fuse holders is thus an
important safeguard. The application of Class R fuses in such
equipment as disconnect switches permits the equipment to
have a high interrupting rating. NEC® Articles 110-9 and
230-65 require that protective devices have adequate
capacity to interrupt short-circuit currents. Article 240-60(b)
requires fuse holders for current-limiting fuses to reject
non-current-limiting type fuses.

Supplementary Overcurrent Protective
Devices for use in Motor Control
Circuits
Branch Circuit vs. Supplemental Overcurrent
Protective Devices
Branch circuit overcurrent protective devices (OCPD) can be
used everywhere OCPD are used, from protection of motors
and motor circuits and group motor circuits, to protection of
distribution and utilization equipment. Supplemental OCPD
can only be used where proper protection is already being
provided by a branch circuit device, by exception [i.e.,
430.72(A)], or if protection is not required. Supplemental
OCPD can often be used to protect motor control circuits but
they cannot be used to protect motors or motor circuits. A very
common misapplication is the use of a supplementary
overcurrent protective device such as a UL 1077 mechanical
overcurrent device for motor branch circuit short-circuit and
ground fault protection. Supplementary OCPDs are incomplete
in testing compared to devices that are evaluated for branch
circuit protection. THIS IS A SERIOUS MISAPPLICATION
AND SAFETY CONCERN!! Caution should be taken to assure
that the proper overcurrent protective device is being used for
the application at hand. Below is a description of popular
supplementary overcurrent protective devices.
Most supplemental overcurrent protective devices have very
low interrupting ratings. Just as any other overcurrent
protective device, supplemental OCPDs must have an
interrupting rating equal to or greater than the available
short-circuit current.

Reliability and Maintenance of
Overcurrent Protective Devices
Modern fuses have several significant advantages over
mechanical overcurrent protective devices - one of those
advantages is reliability. Whether the first day of the electrical
system or years later, it is important that overcurrent protective
devices perform under overload and fault conditions as
intended.
Modern current-limiting fuses operate by very simple, reliable
principles. Fuses do not have to be maintained. By their
inherent design, fuses do not have elements or mechanisms
to calibrate, adjust or lubricate. If and when fuses are called
upon to open on an overcurrent, installing the same type and
ampere rated fuses provides the circuit with new factorycalibrated protection. The original design integrity can be
maintained throughout the life of the electrical system. One
last point on fuse systems; the terminations, clips and
disconnects should be maintained as necessary.
In contrast, circuit breakers are mechanical devices, even
those with electronic sensing, and circuit breakers require
periodic maintenance, testing, and if necessary reconditioning
or replacement. This is required per the circuit breaker
manufacturers' instructions, NFPA 70B Recommended
Practice for Electrical Equipment Maintenance, and NEMA
AB4. If circuit breakers are not properly maintained, the
interrupting rating, circuit component protection, coordination,
and electrical safety may be compromised.
See www.cooperbussmann.com for more information on
Reliability and Maintenance.

Supplemental fuses as listed or recognized to the
UL/CSA/ANCE Trinational 248-14 Standard
These are fuses that can have many voltages and interrupting
ratings within the same case size. Examples of supplemental
fuses are 13⁄32'' X 1 1⁄2'', 5 x 20mm, and 1⁄4'' x 1 1⁄4'' fuses.
Interrupting ratings range from 35 to 100,000 amps.

Motor Circuit Branch Circuit Protection
Motor Circuits – Choice of Overcurrent Protection
Motor circuits have unique characteristics and several
functions, such as short-circuit protection, overload protection
and automatic/ remote start/stop, that may be required.
Sometimes the comment is made that users prefer circuit
breakers because they can be reset. Let’s examine the choice
of either circuit breakers or current- limiting fuses for motor
branch circuit protection.
In the case to be examined, fuses and circuit breakers
(includes magnetic only circuit breakers which are called
MCPs or motor circuit protectors) are sized with the intent to
provide only short-circuit and ground fault protection for the
motor branch circuit protection per 430.52. Other means, such
as overload relays, provide the motor overload protection.
Typical thermal magnetic circuit breakers can only be sized for
motor branch circuit protection (typically 200% - 250% of
motor current) because if they are sized closer, the motor
starting current trips the circuit breaker’s instantaneous
mechanism. Magnetic only circuit breakers (MCPs) are
intentionally not provided with overload capability; they only
operate on short-circuit currents. There are some fuses such
as the FRS-R and LPS-RK fuses that can be sized close
enough for motor running overload protection or backup motor
running protection. But for the discussion in this section,
assume current-limiting fuses are sized only for motor
short-circuit and ground fault protection.
It is important to note that in this protection level being
discussed, a circuit breaker or fuses should only open if there
is a fault on the motor circuit. A separate overload protective
device, such as an overload relays, provides motor overload
protection per 430.32. Here are some important
considerations:
1. OSHA regulation 1910.334(b)(2) Use of Equipment states:
Reclosing circuits after protective device operation. After a circuit is
deenergized by a circuit protective device, the circuit may not be
manually reenergized until it has been determined that the equipment
and circuit can be safely energized. The repetitive manual reclosing of
circuit breakers or reenergizing circuits through replaced fuses is
prohibited. NOTE: When it can be determined from the design of the
circuit and the over-current devices involved that the automatic
operation of a device was caused by an overload rather than a fault
condition, no examination of the circuit or connected equipment is
needed before the circuit is reenergized.
So the speed of reclosing a circuit breaker after a fault is not an
advantage. The law requires that if the condition is a fault (that is the
only reason the circuit breaker or fuses should open on a motor circuit),
then the fault must be corrected prior to replacing fuses or resetting the
circuit breaker.

Consequently, with circuit breaker protection, after a fault condition,

3. Circuit breakers must be periodically tested to verify they mechanical
operate and electrically tested to verify they still are properly calibrated
within specification. The circuit breaker manufacturers recommend this.
Typically circuit breakers should be mechanically operated at least every
year and electrically tested every 1 to 5 years, depending on the service
conditions. Modern current-limiting fuses do not have to be maintained
or electrically tested to verify they still will operate as intended. The
terminations of both circuit breakers and fusible devices need to be
periodically checked and maintained to prevent thermal damage. Plus
fuse clips should be periodically inspected and if necessary maintained.
4. After a circuit breaker interrupts a fault, it may not be suitable for further
service. UL 489, the product standard for molded case circuit breakers,
only requires a circuit breaker to interrupt two short-circuit currents at
its interrupting rating. Circuit breakers that are rated 100 amps or less
do not have to operate after only one short-circuit operation under “bus
bar” short-circuit conditions. If the fault current is high, circuit breaker
manufacturers recommend that a circuit breaker should receive a
thorough inspection with replacement, if necessary. How does one know
a circuit breaker’s service history or what level of fault current that a
circuit breaker interrupts? With modern current-limiting fuses, if the fuse
interrupts a fault, new factory calibrated fuses are installed in the circuit.
The original level of superior short-circuit protection can be there for the
life of the motor circuit.
5. After a fault, the electrician has to walk back to the storeroom to get new
fuses; that is if spare fuses are not stored adjacent to the equipment.
This does require some additional down time. However, if fuses opened
under fault conditions, there is a fault condition that must be remedied.
The electrician probably will be going back to the storeroom anyway for
parts to repair the fault. If properly selected current-limiting fuses are
used in the original circuit, the starter will not sustain any significant
damage or loss of overload calibration.

With circuit breaker protection on motor circuits, after a fault
condition, it may be necessary to repair or replace the starter,
so a trip to the storeroom may be necessary. And if the starter
is not significantly damaged, it may still need to be tested to
insure the let-through energy by the circuit breaker has not
caused the loss of starter overload calibration. Also, the circuit
breaker needs to be evaluated for suitability before placing it
back into service. Who is qualified for that evaluation? How
much time will that take?
In summary, resettability is not an important feature for motor
branch circuit (short-circuit) protection and resettability of the
branch circuit protective device is not a benefit for motor
circuits. As a matter of fact, resettability of the motor branch
circuit overcurrent protective device may encourage an unsafe
practice. The function of motor branch circuit protection is fault
protection: short-circuit and ground fault protection. Faults do
not occur on a regular basis. But when a fault does occur, it is
important to have the very best protection. The best motor
branch circuit protection can be judged by (1) reliability - its
ability to retain its calibration and speed of operation over its
lifetime, (2) current-limiting protection - its ability to provide
Type 2 “No Damage” protection to the motor starter, and (3)
safety - its ability to meet a facility’s safety needs. Modern
current-limiting fuses are superior to circuit breakers for motor
branch circuit protection.

2. The typical level of short-circuit protection for the motor starter provided
by circuit breakers and MCPs is referred to as Type 1. This is because
most circuit breakers are not current-limiting. So, for a loadside fault,
the starter may sustain significant damage such as severe welding of
contacts and rupturing of the heater elements. Or the heater/overload
relay system may lose calibration. This is an acceptable level of
performance per UL 508, which is the product standard for motor
starters. Current-limiting fuses can be selected that can provide Type 2
“No Damage” short-circuit protection for motor starters.

significant downtime and cost may be incurred in repairing or replacing
the starter. With properly selected fuses for Type 2 protection, after the
fault is repaired, only new fuses need to be inserted in the circuit; the
starter does not have to be repaired or replaced.

Ampere (Amp)

Class G Fuses

Class R Fuses

The measurement of intensity of rate of
flow of electrons in an electric circuit. An
ampere (amp) is the amount of current
that will flow through a resistance of one
ohm under a pressure of one volt.
Ampere is often abbreviated as “A”.

480V, 100kA interrupting rating branch
circuit fuses that are size rejecting to
eliminate overfusing. The fuse diameter
is 13⁄32” while the length varies from 15⁄16”
to 21⁄4”. These are available in ratings
from 1A through 60A.

Amp Rating

Class H Fuses

The current-carrying capacity of a fuse.
When a fuse is subjected to a current
above its amp rating, it will open the
circuit after a predetermined period of
time.

250V and 600V, 10kA interrupting rating
branch circuit fuses that may be
renewable or non-renewable. These are
available in amp ratings of 1A through
600A.

These are high performance fuses rated
1
⁄10-600A in 250V and 600V ratings. All
are marked “Current Limiting” on their
label and all have a minimum of 200kA
interrupting rating. They have identical
outline dimensions with the Class H
fuses but have a rejection feature which
prevents the user from mounting a fuse
of lesser capabilities (lower interrupting
capacity) when used with special Class
R Clips. Class R fuses will fit into either
rejection or non-rejection clips.

Amp Squared Seconds, l2t

Class J Fuses

The measure of heat energy developed
within a circuit during the fuse’s
clearing. It can be expressed as
“melting l2t”, “arcing l2t” or the sum of
them as “Clearing l2t”. “l” stands for
effective let-through current (RMS),
which is squared, and “t” stands for time
of opening, in seconds.

These fuses are rated to interrupt a
minimum of 200kA AC. They are labeled
as “Current-Limiting”, are rated for
600Vac, and are not interchangeable
with other classes.
Class K Fuses

Class T Fuses
An industry class of fuses in 300V and
600V ratings from 1A through 1200A.
They are physically very small and can
be applied where space is at a
premium. They are fast acting fuses
with an interrupting rating of 200kA
RMS.
Classes of Fuses

The amount of time from the instant
the fuse link has melted until the
overcurrent is interrupted, or cleared.

These are fuses listed as K-1, K-5, or
K-9 fuses. Each subclass has
designated I2t and lp maximums. These
are dimensionally the same as Class H
fuses, and they can have interrupting
ratings of 50k, 100k, or 200kA. These
fuses are current-limiting. However, they
are not marked “current-limiting” on their
label since they do not have a rejection
feature.

Breaking Capacity

Class L Fuses

Clearing Time

(See Interrupting Rating)

These fuses are rated for 601 through
6000A, and are rated to interrupt a
minimum of 200kA AC. They are labeled
“Current-Limiting” and are rated for
600Vac. They are intended to be bolted
into their mountings and are not
normally used in clips. Some Class L
fuses have designed in time-delay
features for all purpose use.

The total time between the beginning of
the overcurrent and the final opening of
the circuit at rated voltage by an
overcurrent protective device. Clearing
time is the total of the melting time and
the arcing time.

Arcing I2t
Value of the I2t during the arcing time
under specified conditions.
Arcing Time

Cartridge Fuse
A fuse consisting of a current
responsive element inside a fuse tube
with terminals on both ends.
Class CC Fuses
600V, 200kA interrupting rating, branch
circuit fuses with overall dimensions of
13
⁄32” x 11⁄2”. Their design incorporates a
rejection feature that allows them to be
inserted into rejection fuse holders and
fuse blocks that reject all lower voltage,
lower interrupting rating 13⁄32” x 11⁄2” fuses.
They are available from 1⁄10A through
30A.

432

The industry has developed basic
physical specifications and electrical
performance requirements for fuses with
voltage ratings of 600V or less. These
are known as standards. If a type of
fuse meets the requirements of a
standard, it can fall into that class.
Typical classes are K, RK1, RK5, G, L,
H, T, CC, and J.

Current Limitation
A fuse operation relating to short circuits
only. When a fuse operates in its
current-limiting range, it will clear a short
circuit in less than 1⁄2 cycle. Also, it will
limit the instantaneous peak let-through
current to a value substantially less than
that obtainable in the same circuit if that
fuse were replaced with a solid
conductor of equal impedance.

Dual Element Fuse

Melting I2t

Peak Let-Through Current, lp

Fuse with a special design that utilizes
two individual elements in series inside
the fuse tube. One element, the spring
actuated trigger assembly, operates on
overloads up to 5-6 times the fuse
current rating. The other element, the
short circuit section, operates on short
circuits up to their interrupting rating.

Value of the I2t during the melting time
of the fuse link under specified
conditions.

The instantaneous value of peak current
let-through by a current-limiting fuse,
when it operates in its current-limiting
range.

Electrical Load

“NEC®” Dimensions

That part of the electrical system which
actually uses the energy or does the
work required.

These are dimensions once referenced
in the National Electrical Code. They are
common to Class H and K fuses and
provide interchangeability between
manufacturers for fuses and fusible
equipment of given ampere and
voltage ratings.

Fast-Acting Fuse
A fuse which opens on overload and
short circuits very quickly. This type of
fuse is not designed to withstand
temporary overload currents associated
with some electrical loads.
Fuse
An overcurrent protective device with a
fusible link that operates and opens the
circuit on an overcurrent condition.
High Speed Fuses
Fuses with no intentional time-delay in
the overload range and designed to
open as quickly as possible in the
short-circuit range. These fuses are
often used to protect solid-state devices.
Inductive Load
An electrical load which pulls a large
amount of current—an inrush current—
when first energized. After a few cycles
or seconds the current “settles down” to
the full-load running current.

Melting Time
The amount of time required to melt the
fuse link during a specified overcurrent.
(See Arcing Time and Clearing Time.)

Resistive Load
An electrical load which is characteristic of
not having any significant inrush current.
When a resistive load is energized, the
current rises instantly to its steady-state
value, without first rising to a higher value.
RMS Current

The unit of measure for electric
resistance. An ohm is the amount of
resistance that will allow one ampere to
flow under a pressure of one volt.

The RMS (root-mean-square) value of
any periodic current is equal to the value
of the direct current which, flowing through
a resistance, produces the same heating
effect in the resistance as the periodic
current does.

Ohm’s Law
The relationship between voltage,
current, and resistance, expressed by
the equation E = IR, where E is the
voltage in volts, I is the current in amps,
and R is the resistance in ohms.
One Time Fuses
Generic term used to describe a Class
H non-renewable cartridge fuse, with a
single element.
Overcurrent

Interrupting Rating — IR

Overload

(Breaking Capacity)

Can be classified as an overcurrent
which exceeds the normal full load
current of a circuit. Also characteristic of
this type of overcurrent is that it does
not leave the normal current carrying
path of the circuit—that is, it flows from
the source, through the conductors,
through the load, back through the
conductors, to the source again.

SCCR
See Short-Circuit Current Rating
Semiconductor Fuses
Fuses used to protect solid-state devices.
See “High Speed Fuses.”
Short-Circuit
Can be classified as an overcurrent which
exceeds the normal full load current of a
circuit by a factor many times (tens,
hundreds or thousands greater). Also
characteristic of this type of overcurrent is
that it leaves the normal current carrying
path of the circuit—it takes a “short cut”
around the load and back to the source.
Short-Circuit Current Rating (SCCR)
The maximum short-circuit current an
electrical component can sustain without
the occurrence of excessive damage
when protected with an overcurrent
protective device.
Short-Circuit Withstand Rating
Same definition as short-circuit rating.

(See Interrupting Rating)

The rating which defines a fuse’s ability
to safely interrupt and clear short
circuits. This rating is much greater than
the ampere rating of a fuse. The NEC®
defines Interrupting Rating as “The
highest current at rated voltage that an
overcurrent protective device is intended to interrupt under standard test
conditions.”

A fuse in which the element, typically a
zinc link, may be replaced after the fuse
has opened, and then reused. Renewable
fuses are made to Class H standards.

Ohm

A condition which exists on an electrical
circuit when the normal load current is
exceeded. Overcurrents take on two
separate characteristics—overloads and
short circuits.

Single-Phasing
That condition which occurs when onephase of a three-phase system opens,
either in a low voltage (secondary) or
high voltage (primary) distribution
system. Primary or secondary singlephasing can be caused by any number
of events. This condition results in
unbalanced currents in polyphase
motors and unless protective measures
are taken, causes overheating and
failure.
Threshold Current
The symmetrical RMS available current
at the threshold of the current-limiting
range, where the fuse becomes
current-limiting when tested to the
industry standard. This value can be
read off of a peak let-through chart
where the fuse curve intersects the A-B
line. A threshold ratio is the relationship
of the threshold current to the fuse’s
continuous current rating.
Time-Delay Fuse
A fuse with a built-in delay that allows
temporary and harmless inrush currents
to pass without opening, but is so
designed to open on sustained
overloads and short circuits.

Voltage Rating
The maximum open circuit voltage in
which a fuse can be used, yet safely
interrupt an overcurrent. Exceeding the
voltage rating of a fuse impairs its ability
to clear an overload or short circuit
safely.

Circuit Protection Products for the Electrical Industry

Cooper Bussmann® Fuse
Cross Reference &
Low-Peak® Upgrade
The left column represents Cooper Bussmann and
competitors’ part numbers. The right column
represents the Cooper Bussmann upgrades.
The Cooper Bussmann® fuse upgrade offers
superior performance while reducing the number of
SKUs that need to be in stock. Low-Peak® fuses
feature a high degree of current limitation, which
will provide the best component protection and may
reduce the arc-flash hazard. Listings are alphanumerical by fuse class and fuse catalog symbol.
This list is only a consolidated cross reference to
some of our most common products. For a much
more extensive database please consult the
Product Profiler competitor cross-reference. Just
visit www.cooperbussmann.com and click on the
magnifying glass icon in the upper right corner.

Because competitors’ products may differ from Cooper Bussmann products, it is recommended that each application be checked for
required electrical and mechanical characteristics before substitutions are made. Cooper Bussmann is not responsible for misapplications
of our products. Overcurrent protection is application dependent. Consult the latest catalogs and application literature, or contact our
Application Engineering Department at (636) 527-1270.
