Low-Peak® Time-Delay, Class L Fuses

O-RING SEALS
Formation of arc gas within fuse
body suppresses arcing; lowers
arcing I2t energy. O-ring seals
maximize pressure build-up during
current limiting action. Also volume
of sand is critical. Slight loss can
adversely impact on current limiting action. O-ring seals insure filler
retention. They compensate to a
degree for switchgear misalignment, and expansion and contraction of mounting surfaces
with change in load to no-load
conditions.

SAND FILLER
High grade silica-sand filler.
Accelerates response of fuse to
short-circuits by having quenching
effect upon the fuse arc.
Substantially contributes to current
limiting action.

99.9% PURE SILVER
FUSELINKS
Embody “silver-sand” design.
99.9% pure silver links; silicasand filler. The high conductivity of
silver gives low watt loss and low
operating temperature at normal
current levels; minimizes total
clearing I2t fault energy let-thru…
state-of-art fuse design. High
degree of current limitation holds
down fault currents and levels of
destructive energy. (Although other
link materials can provide current
limitation, they do not equal that
of silver.)

• All-purpose silver linked fuse for both overload and shortcircuit protection for high capacity systems (mains and large
feeders).
• Time-delay (minimum of four seconds at five times amp rating)
for close sizing.
• Current limiting action of the fuse generally affords considerable reduction in bus bracing.
• Interrupting rating of 300,000 amperes complies with
NEC Sections 110-9 and 230-65 for today’s large capacity
systems.
• O-ring seals maximize pressure build-up during current limiting
action and ensure filler retention.
• High grade silica-sand filler; accelerates response of fuse to
short-circuits by having quenching effect upon the fuse arc.
• 99.9% pure silver fuselinks. The high conductivity of silver
gives low watt loss and low operating temperature at normal
current levels; minimizes total clearing I 2t fault energy let-thru.
• Selective coordination (blackout prevention)
• Glass melamine tube.
• Silver plated end bells.
• Reducers not necessary.

• Compact branch-circuit units with high interrupting rating
and current limitation.
• With a 600 volt rating, they can be used in 120/208,
120/240 and 277/480 volt circuits.
• Length variations relative to case size make the “rejection”
type fuses.
• SC fuses with ampere ratings above 6 amps have a degree
of overload time-delay which permits them to pass temporary overloads. At 200% load, they have a minimum opening time of 12 seconds.

• Current-limiting devices designed specially for use on
welder circuits only.
• Time-current characteristics are designed to hold on the
intermittent overloading encountered in welder operation,
while providing short-circuit protection to the circuit and
equipment.
• Welder limiters have excess current capacity in the operating range as needed for this type of service.
• Because of the special characteristics of the welder limiters,
they are not intended for application on general-use circuits.

SAMI -2

• Innovative design, covers exposed terminals and contacts
of Bussmann fuseblocks.
• Fits most competitive fuseblocks.
• Buss Yellow light on indicating SAMI shows when the fuse
is open—helps trouble shoot the system and reduces
downtime.
• All versions are reusable—no need to pay for indication
every time a fuse opens.
• Indication contacts have teeth to break oxidation layer on
the existing fuse endcap to provide a clear signal path.
• Less than .6mA leakage current at 600 volt.
• Visual marking of line and load side.
• SAMI cover ends can easily be cut away if necessary, to fit
cover over existing wiring or to fit most safety switches.
• Dead front construction provides added protection against
accidental contact by maintenance personnel.
• Labels are provided with the SAMI fuse cover for writing in
circuit or fuse information.
• One cover is required for each pole.

Indicating feature requires a minimum of 90Vac or 115Vdc to illuminate lamp.

All enclosed switches are provided with a black handle; however, most handles can be substituted with a red and yellow handle if desired.
Please substitute the handle suffix code (2nd and 3rd from last characters) with the red/yellow handle catalog number suffix from page 3.12.
There is no additional price adder for changing to a red/yellow handle of equal ratings and style.
A red/yellow selector handle for an ENF161-3PBJA can be substituted for the black selector handle by using the "YJ" suffix instead of the "BJ"
suffix, new catalog #ENF161-3PYJA.

Enclosures are rated as listed, selector handles are only NEMA rated 1, 3R, 12. The overall NEMA rating of an enclosed switch with a selector handle is 1, 3R, 12.
IEC rated only.

High Speed Fuses

North American Style Fuseblocks
Modular Style
Bussmann offers a comprehensive line of fuse bases that provide the user with design and manufacturing flexibility. Two
identical half bases make up a Buss Modular fuse base.
These “split” units can be panel mounted any distance
apart to accommodate any length fuse.
Stud Type
The simpler design is the C5268 Series Modular fuse
base. With this design, the fuse terminal and cable (with
termination) are mounted on the same stud, minimizing labor
needed for installation. The stud Type Base is available in the
configuration shown in the table below. (Must order 2 pieces
per fuse, they do not come in pairs.)

High Speed Fuses

Indicator System
Indicators
Typower ZILOX fuses are available with three different indicator systems.
Visual Indicator
The indicator situated in one cover plate is clearly visible as
soon as the fuse has operated. The minimum voltage for
operating the indicator is 20V.
Type T Indicator
The indicator is situated on one cover plate with a cover
plate tag to accommodate an auxiliary switch. The minimum
voltage for operating the indicator is 20V. A special low voltage indicator (1.5V) is available on request.
Type K Indicator
This indicator is situated on the fuse body. It is covered by
an adaptor for snap-on mounting of an auxiliary switch. The
operating voltage of the indicator is 1.5V. As a matter of
safety, the factory mounted adaptor must not be removed
from the fuse.

Microswitch
The Typower ZILOX fuses with either type T indicator or
type K indicator can be equipped with a microswitch for
remote electrical indication of fuse operations. All microswitches have one normally open and one normally closed
contact. Ratings are 2A, 250Vac.

Select Fuses designed and tested to:
• IEC 60269: Part 4
• UL Recognized, Std. 248-13
Bussmann offers a full line of Ferrule Style (cylindrical and
clip-mounted) fuses, designed and tested to meet standards
and requirements in various locations around the world. Their
unique design and construction provide:
• Superior cycling capability
• Low energy let-thru (I2t)
Ferrule fuses provide an excellent solution for small UPS,
small AC drives and other low power applications where
space is at a premium.
Accessories
Ferrule fuses may be mounted in fuse clips, fuseholders,
fuseblocks or fused switches. A variety of products are available to suit most end-use requirements.

All Bussmann Ferrule fuses—except 690V—have been tested
at their rated voltage. The 690V Ferrule fuse has been tested
to the IEC 60269 standard, which requires clearing at the
rated voltage +5%.

Medium Voltage Fuses and Fuse Links

BBU Boric Acid Fuse-Features
Construction
Principle parts of the replaceable BBU
fuse unit are shown in the cross section view. Main operating parts are
the silver element, arcing rod, boric
acid cylinder, and spring. A glass
epoxy tube encloses the assembly.

ption is achieved by the action of an
arcing rod and a charged spring, elongating the arc through a boric acid
chamber upon release by the fuse
element.

When the fuse operates, the upward
motion of the spring forces the top of
the arcing rod to penetrate the upper
seal, striking the latch mechanism.
On indoor applications, this action
caused the blown fuse indicator to
actuate.
When replacing the blown fuse, the
end fittings should be removed from
the operated fuse unit, and if undamaged, clamped onto the new fuse
unit.

The use of a pure silver element and
Nichrome wire strain element makes
the BBU less susceptible to outages
caused by vibration, corona corrosion,
and aging of the fuse elements.

Application
The BBU Boric acid Fuse provides
effective protection for circuits and
equipment which operate on voltage
systems up to 34,500V. They can be
used on industrial distribution systems and all fuses are designed for
use on the following:
Power Transformers
Feeder Circuits
Distribution Transformers
Element
Melts

Vapor
Rod withdraws,
quenches
elongating arc
and vaporizing arc at first
current zero
Boric Acid

At high temperatures, boric acid
decomposes producing a blast of
water vapor and inert boric anhydride.
Electrical interruption is caused by the
steam extinguishing the arc, as the
arc is being elongated through the
cylinder.

BBU Fuse Construction
The components are housed in a
fiberglass reinforced resin tube with
plated copper contacts. Positive connection is maintained between the
arcing rod and contact with a sliding
tulip contact.

Operation
BBU Expulsion Fuses utilize the
proven performance of boric acid to
create the de-ionizing action needed
to interrupt the current. Fault interru-

Higher particle turbulence of the boric
acid causes the rate of de-ionization
in the cylinder to exceed the ionization of the electrical arc. Both high
and low current faults are interrupted
in the same manner with no foreign
material other than the boric acid
required. This enables the fuse to
interrupt short circuits within one-half
cycle and prevents the arc from
restriking after a current zero.
After interruption, the gases are
expelled from the bottom of the fuse.
The arching rod is prevented from
falling back into its original position by
a friction stop at the top of the fuse
unit.

Metal-enclosed Switchgear
Pad Mount Switches
BBU Fuse units can be used in
indoor applications, and can be used
to directly replace competitive equivalent units.

BBU End Fittings
End Fittings are required to complete
the electrical connection between the
fuse unit and the live parts and
mounting.
End fittings are positioned on the top
and bottom of the fuse unit. They
can be used over again if they remain
undamaged.
The indoor fittings accept a Muffler
attachment to limit noise and contamination to indoor equipment. The
blown fuse indicator located on the
top end fitting, provides visual indication of a faulted fuse unit.

E-RATED MEDIUM VOLTAGE FUSES:
Meets E requirements per ANSI C37.46
Meets General Purpose requirements per ANSI C37.40
FOR TRANSFORMER AND FEEDER PROTECTION
VOLTAGE RATING: 5.5 KV
INTERRUPTING RATING: 63KA Maximum Sym.
CURRENT LIMITING
CONSTRUCTION:
• Silver element in a double concentric helical configuration
• Silica filler
• Silver plated copper terminals and endcaps
• Filament wound, glass epoxy fuse tube
FEATURES:
• General Purpose Fuses. Bussmann’s medium voltage
fuses provide general purpose protection and are capable of
interrupting fault currents up to 63,000A RMS sym.
• Clip-lock and bolt-in style available in double and triple
barrel fuse designs.
• Indoor and Outdoor Usage. The filament wound, glass
epoxy fuse tube provides UV and moisture protection for the
fuse. This makes Bussmann’s medium voltage fuses suitable
for both indoor and outdoor applications.
• Open Fuse Indication. Indicator travel distance is 16mm.
• Operating Frequency: 50/60 Hz
Current-limiting medium voltage fuses are
classified into three categories:
Full Range - defined by ANSI as “a fuse capable of interrupting all currents from the maximum rated interrupting
current down to the minimum continuous current that causes 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 normal 60 cycle current
that will melt its element.
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 in one hour.” Not all currents fall within this range. It is possible to receive an overcurrent lower
than the value given by the one hour criterion.
Back-up - defined by ANSI C37.40 as “a fuse capable of
interrupting all currents from the maximum rated interrupting
current down to the rated minimum interrupting current.”
The minimum rated 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 in series with
the back-up rated fuse.

This selection table has been 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 fuse links are recommended where possible in the interests of standardization.
4. Wherever possible, 10 inch long FO1 fuse links 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 Bussmann.

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
20 mA. 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.

• Tron® HRCII-C fuses are designed to withstand inrush currents on typical motor start-ups while offering high current
limitation in the short-circuit region.
• The Tron® HRCII-C fuses can be sized close to the motor
nameplate rating.
• Closer protection is offered for many motor sizes with the
availability of these additional fuse ratings.
• Tron® HRCII-C fuses have a high degree of current limitation
greatly reducing the magnetic forces and thermal stresses
produced in today’s high capacity systems.

• Industrial duty fuses with ceramic bodies.
• The excellent current limiting characteristics of fast-acting
HRCI-J fuses limits damage to equipment and installations
by the thermal and magnetic energy associated with a
large short-circuit fault current.
• Overload characteristics limit cable damage due to low
overload currents.

• Buss DIN-Rail Adapters permit secure, positive snap-on
mounting of Buss 0 to 30 ampere fuseblocks (one, two, or
three pole) on the various size rails. (Rail mounting eliminates costly and time consuming drilling, tapping, and
screw mounting.)
• Molded from “Lexan™ 141”…a very high strength but
flexible material.
• Adapter mechanically locks into mounting hole of fuseblock
in seconds to become an integral part of the block.
• One adapter is required for Buss one and two pole 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.

Fuse Technology

Circuit Protection
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.
Overloads
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.)
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
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

210

Bussmann®

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.”
Voltage Rating
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.
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.
Ampere Rating
Every fuse has a specific ampere rating. In selecting the ampere
rating of a fuse, consideration must be given to the type of load
and code requirements. The ampere rating of a fuse normally
should not exceed the current carrying capacity of the circuit. For

Bussmann®

Fuse Technology

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 ampere rating is permitted to be
greater than the current carrying capacity of the circuit. A typical
example is the motor circuit; dual-element fuses generally are
permitted to be sized up to 175% and non-time-delay fuses up
to 300% of the motor full-load amperes. As a rule, the ampere
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 branch-circuit, 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.

This diagram shows the minimum ratios of ampere ratings of LOW-PEAK
YELLOW fuses that are required to provide “selective coordination”
(discrimination) of upstream and downstream fuses.

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

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,
60 hz) 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.

Operating Principles of Bussmann® Fuses
The principles of operation of the modern, current-limiting Buss
fuses are covered in the following paragraphs.
Non-Time-Delay Fuses
The basic component of a fuse is the link. Depending upon the
ampere 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. BUSS® LIMITRON®
and T-TRON® fuses are both single-element fuses.
Under normal operation, when the fuse is operating at or near its
ampere 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 shortcircuit 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 40,000A 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 three-thousandths 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) Shortcircuit 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).

There are many advantages to using these fuses. Unlike single-element fuses, the Bussmann® dual-element, time-delay fuses can be sized closer to provide both high performance shortcircuit 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 LOWTM
PEAK® Dual-Element Fuses, LPJ_SP, and CUBEFuse , TCF, can be sized at 150% of motor full load amperes. This closer fuse sizing may provide many advantages such as: (1)
smaller fuse and block, holder or disconnect ampere rating and physical size, (2) lower cost due to lower ampere 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.

Artistic liberty is taken to illustrate the internal portion of this fuse. The real fuse has a non-transparent tube and special small granular, arc-quenching material completely filling the
internal space.

Figure 7. The true dual-element fuse has distinct and separate overload
element and short-circuit element.

Figure 9. Short-circuit operation: Modern fuses are designed with minimum metal in the
restricted portions which greatly enhance their ability to have excellent current-limiting
characteristics – minimizing the short circuit let-through current. A short-circuit
current causes the restricted portions of the short-circuit element to vaporize and arcing
commences. The arcs burn back the element at the points of the arcing. Longer arcs result,
which assist in reducing the current. Also, the special arc quenching filler material contributes to extinguishing the arcing current. Modern fuses have many restricted portions,
swhich results in many small arclets – all working together to force the current to zero.

Spring

After
Figure 8. Overload operation: Under sustained overload conditions, the trigger spring
fractures the calibrated fusing alloy and releases the “connector”. The insets represent a
model of the overload element before and after. The calibrated fusing alloy connecting the
short-circuit element to the overload element fractures at a specific temperature due to a
persistant overload current. The coiled spring pushes the connector from the short-circuit
element and the circuit is interrupted.

Figure 10. Short-circuit operation: The special small granular, arc-quenching material
plays an important part in the interruption process. The filler assists in quenching the arcs;
the filler material absorbs the thermal energy of the arcs, fuses together and creates an
insulating barrier. This process helps in forcing the current to zero. Modern current-limiting fuses, under short-circuit conditions, can force the current to zero and complete the
interruption within a few thousandths of a second.

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.
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.

Fuse Technology

This particular plot reflects the characteristics of a 200A, 250V,
LOW-PEAK YELLOW 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 ampere ratios, these time-current curves permit close or critical analysis of coordination.
Better Motor Protection in Elevated Ambients
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 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.

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 single-phasing
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 YELLOW™
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 10,000A
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 fuseholder rating cannot be installed.

Class R Fuses
Class R (“R” for rejection) fuses are high performance, ⁄Ω¡º to 600A
units, 250V and 600V, having a high degree of current limitation
and a short-circuit interrupting rating of up to 300,000A (rms symmetrical). BUSS Class R's include Classes RK1 LOW-PEAK YELLOW™ and LIMITRON® fuses, and RK5 FUSETRON® fuses. They
have replaced BUSS 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 fuseholders 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 fuseholders for current-limiting fuses to reject
non-current-limiting type fuses.

Glossary of Terms

Ampere
The measurement of intensity of rate of flow of
electrons in an electric circuit. An ampere is
the amount of current that will flow through a
resistance of one ohm under a pressure of one
volt.
Ampere Rating
The current-carrying capacity of a fuse. When
a fuse is subjected to a current above its
ampere rating, it will open the circuit after a
predetermined period of time.
Ampere Squared Seconds, l2t
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.
Arcing Time
The amount of time from the instant the fuse
link has melted until the overcurrent is interrupted, or cleared.
Breaking Capacity
(See Interrupting Rating)
Cartridge Fuse
A fuse consisting of a current responsive element inside a fuse tube with terminals on both
ends.
Class CC Fuses
600V, 200,000A interrupting rating, branch
circuit fuses with overall dimensions of ⁄‹Ω£™∑ ≈
1⁄Ω™∑. 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 ⁄‹Ω£™∑ ≈ 1⁄Ω™∑ fuses. They are available from
⁄Ω¡ºA through 30A.
Class G Fuses
480V, 100,000A interrupting rating branch circuit fuses that are size rejecting to eliminate
overfusing. The fuse diameter is ⁄‹Ω£™∑ while
the length varies from 1ﬁΩ¡§∑ to 2⁄Ω¢∑. These are
available in ratings from 1A through 60A.
Class H Fuses
250V and 600V, 10,000A interrupting rating
branch circuit fuses that may be renewable or
non-renewable. These are available in ampere
ratings of 1 amp through 600A.
Class J Fuses
These fuses are rated to interrupt a minimum
of 200,000A ac. They are labelled
as “Current-Limiting”, are rated for 600vac,
and are not interchangeable with other classes.

Class K Fuses
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 50,000, 100,000, or 200,000 A.
These fuses are current-limiting. However,
they are not marked “current-limiting” on their
label since they do not have a rejection feature.
Class L Fuses
These fuses are rated for 601 through 6000A,
and are rated to interrupt a minimum of
200,000A ac. They are labelled “CurrentLimiting” 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.
Class R Fuses
These are high performance fuses rated ⁄Ω¡º600A in 250V and 600V ratings. All are
marked “Current Limiting” on their label
and all have a minimum of 200,000A 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.
Class T Fuses
An industry class of fuses in 300V and 600V
ratings from 1 amp through 1200A. They are
physically very small and can be applied
where space is at a premium. They are fast
acting and time-lag fuses, with an interrupting
rating of 200,000A RMS.
Classes of Fuses
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.
Clearing Time
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.
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 ⁄Ω™
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
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.
Electrical Load
That part of the electrical system which actually uses the energy or does the work
required.
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 solidstate 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.
Interrupting Capacity
See Interrupting Rating
Interrupting Rating
(Breaking Capacity)
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.”
Melting Time
The amount of time required to melt the fuse
link during a specified overcurrent. (See
Arcing Time and Clearing Time.)
“NEC” Dimensions
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.
Ohm
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.

Glossary of Terms

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 amperes, and R is the resistance in
ohms.
One Time Fuses
Generic term used to describe a Class H
nonrenewable cartridge fuse, with a single
element.
Overcurrent
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.
Overload
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.
Peak Let-Through Current, lp
The instantaneous value of peak current letthrough by a current-limiting fuse, when it
operates in its current-limiting range.
Renewable Fuse (600V & below)
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.
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.

232

R.M.S. Current
The R.M.S. (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.
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 Rating
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.
Single Phasing
That condition which occurs when one phase
of a three phase system opens, either in a low
voltage (secondary) or high voltage (primary)
distribution system. Primary or secondary single phasing 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.
Withstand Rating
The maximum current that an unprotected
electrical component can sustain for a specified period of time without the occurrence of
extensive damage.
