l

The NH DIN low voltage fuse system offered by Cooper Bussmann includes fuse links bearing the VDE mark:
Bussmann fuses are manufactured to meet the requirements of IEC 60269.

NH DIN Fuse Links with Dual Indication

Historically, the majority of NH-fuse links according to DIN 43 620 had two different types of indicator systems. The most
common type has the indicator located on the top end plate of the fuse link. In most cases this is used for visual indication,
although it can also be used to operate a micro-switch where remote indication is required. The second type of indicator is
located in the centre of the ceramic body of the fuse link.
When used in conjunction with NH open style fuse bases, the top indicator provides the end-user with effective visual
indication of operation of the fuse link. However, when used in fuse rails or fuse switch-disconnectors, it is extremely
difficult to identify the operated fuse link. This is when centre indication is required
The dual indicating NH fuse links from Bussmann incorporates the top and centre indicator systems, and is available at
500V AC for ratings from 6 to 630Amps.

Low Voltage Industrial Fuse Links
BRITISH STANDARD LOW VOLTAGE INDUSTRIAL FUSE LINK - APPLICATION INFORMATION
The Bussmann standard range of high breaking capacity fuse links for low voltage industrial and general purpose applications meet the requirements of BS88
and IEC60269. By using advanced fuse technology the current ratngs up to 400A have compact dimensions but still within the standardised dimensional and
performance requirements. These designs have been optimised for 415/240V systems. The standard range of fuse links are available from 2-1250A in the
following tag forms: OFFSET BLADED - OFFSET BOLTED - CENTRE BOLTED.
Supplementary ranges cover applications up to 690V a.c. and 500V d.c. including those with non-standard tag fixings.
Bussmann fuse links are manufactured under Quality Systems independently assessed to ISO 9001 and appropriate ratings carry the ASTA 20 endorsement.
APPLICATION DATA

Zs OHMS IMPEDANCE VALUES

CAPACITOR CIRCUITS

One of the long standing advantages of fuse protection
is that fuse selection is relatively simple and effective.

The rules for protection against indirect contact are
given in Chapter 413 of the Wiring Regulations.

The following notes cover the majority of applications.
For further information contact Bussmann technical
services on 01509 882699.

For a TN System a disconnecting time not exceeding
5s is permitted for a distribution circuit. The maximum
values of earth fault loop impedance (Zs) corresponding
to a disconnecting tme of 5s for nominal voltage to
earth (Uo) of 240V for Bussmann gG fuse links.

In capacitor circuits, for example power factor correction,
the fuse link should be chosen with a current rating
greater than 1.5 times the rated capacitor current.
This takes account of the high transient inrush current,
circuit harmonics and capacitor tolerances.

The current rating of the fuse link 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 occurence.

AMBIENT TEMPERATURE

A de-rating in terms of current of 0.5% per oC above
an ambient of 35oC is recommended.
BREAKING CAPACITY

The standardised values of Breaking Capacity are
80kA for voltages of 415V a.c. and above, and 40kA
for d.c. applications.

om

In view of the above it is recommended that the practice
of designs based upon conductor temperatures of
70oC be regarded as the norm. In accordance with
clause 512-02-01 of the Wiring Regulations the
equipment manufacturer should be consulted to
ascertain the reduction of nominal current rating of
the equipment if conductor temperatures exceeding
70oC are used. In addition an overriding factor is often
voltage drop consideration.

Ω

po

There is an increasing move away from 70oC P.V.C.
insulation to materials which are more environmentally
friendly, for example 90oC 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 70oC
in normal service.

CABLE RATINGS

l

Bussmann fuse links with gG characteristics protect
associated cables against both overload and short
circuit current, provided that the current rating of the
fuse link IN is equal or less than the current carrying
capacity of the cable Iz.

In motor circuits, the motor starter will provide the
overload protection and the fuse links will provide the
short circuit protection. The maximum size of fuse link
that can be used depends upon the type of cable used
and is determined in accordance with the Wiring
Regulations using the appropriate K factor. The following
table gives maximum sizes of fuse links that are
recommended for two popular cables with copper
conductors, 70oC P.V.C. (K=115) and 90o C thermosetting
(K=143).

DISCRIMINATION
All fuse links will give a discrimination 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 discriminate with a downstream fuse rated
at 100A.

MOTOR CIRCUITS

Co-ordination recommendations are made by the
manufacturers of motor starters in accordance with
IEC 60947-4-1. To give the desirable type 2 co-ordination
with fuse links, tests are performed with the latest gG
or gM fuse links, to BS88 or IEC60269 which have
pre-arcing I2 t values toward the bottom specified limits.
This means that Bussmann fuse links are suitable to
give type 2 co-ordination.

CIRCUIT LOADING

nt

Reference should also be made to the appropriate
Wiring Installation rules, in the UK the 16th Edition of
the IEE Wiring Regualtions for Electrical Installations
which aligns with IEC 60364.

CURRENT AND ENERGY LIMITATION
The Bussmann range of fuse links have pre-arcing I 2t
values towards the bottom limits of the standards.
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 fuse links.
TRANSFORMERS
When fuse links are used on the primary side of
transformers the normal current rating of the fuse links
should be at least twice the nominal transformer primary
current.
FLUORESCENT LIGHTING
The normal current rating of the fuse link should be
at least twice the normal full load current of the maximum
number of lights to be switched simultaneously.

Extended dual ratings of motor circuit protection fuse
links with gM characterstics are available in most
popular sizes of fuse links to extend the use of associated
equipment with appropriate economies. In the majority
of applications, gG fuse links are used. It is not essential
for gM fuse links to be used for motor circuit protection,
they simply extend the utilisation of standard equipment.
The attached table shows the recommended fuse links
at 415V. In most applications the run-up time is less
than five seconds and duty is infrequent - no more
than twice per house. The next larger rating should
be used for more arduous conditions.

Low-Peak® Time-Delay, CLASS L Fuses

SAND FILLER

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.

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; silica-sand 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.)

• 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.

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.

Notes
a)

17.5kV fuse links in 10/12 dimensions are offered, since some
switchgear in the 10/12 series is suitable for use at higher
voltages.

b)

Fuse links listed are normally for indoor use but versions
suitable for outdoor use are also available in the same ratings
and dimensions. For outdoor versions of the ‘S’ range, replace
the ‘S’ with a ‘T’ when ordering - for example ‘TDLSJ’

c)

* All the fuse link code references listed in the proceeding
tables are for striker fitted versions, for non-striker versions
please replace the letter ‘S’ with the letter ‘N’ in the code for example ‘SDLNJ’.

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.

Fused Disconnect Switch
For use with Telpower® Fuses Type TPL-B.
Ampere Ratings: 70-250 Amperes
Voltage Rating: 80 Volts DC
U.L. Withstand Rating: 100,000A
Agency Information:
U.L. Recognized (investigated to U.L. 1801) as a
disconnect switch for the interruption of load current
by means of withdrawing the fuse pullout.
Guide QPQY2, File E97649.

General Information:
• High amp version of Bussmann 15800 series
Fused Disconnect Switch.
• 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.
• For use with the following fuses only:
Main: Telpower® TPL-B 70-250 Amperes.
Alarm: Bussmann GMT-A only.
• Alarm output with wire wrap terminal or connection to
.063” thick common alarm bus.
• Hardware included:
Load: washer, split lockwasher, and 5/16 _ 18 nut.

• Thermoplastic housing material U.L. rated 94V-0, 150°C.
• Application Note: 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 ±.02 in. (± .50mm) to
allow for variation in the distance between the TP158HC
mounting flange and the line bus bar (see dimensional
data). Equipment should be designed to eliminate any
relative movement between the TP158HC mounting flange
and the line bus bar.
• Application Note: The alarm circuit is not intended for
precharging of capacitive circuits. Alarm circuit current
1 Ampere maximum.

British Standard Fuse Holders and Accessories
CAM ASTER HRC Fuse Holders - Introduction

A patented range of fully shrouded HRC Fuse Holders designed to
accomodate offset bolted tag HRC fuse links to BS88: Parts 1 & 2;
IEC 60269-1 & 2. All Camasters are rated at 690Vac.
The compact dimensioned 32A Fuse Holder, type CM32FC and
CM20F accept the A1 size fuse link NITD 2 to 32 Amps. The standard
32A Fuse Holder, type CM32F and CM20F accept the A2 size fuse
link AAO 2 to 32 Amp. The 63A unit, type CM63F accepts the A3 size
fuse link BAO 40 to 63 Amp and the 100 Amp unit,type CM100F
accepts fuse link type OSD 80 to 100 Amps, which has compact A3
fixing centres.

s.

co

m

The Fuse Holders are supplied as front connecting as standard but
can be readily converted to front/back stud or double back stud
connection types at the point of installation, using the appropriate
size back stud accessories.

nt

CAMASTER Fuse Holders are offered with the following features:
• Advanced patented design incorporating a high level of innovation

ne

with enhanced performance characteristics.
• Camaster Fuse Holders fully comply with the requirements of BS88

po

section 2.2 (IEC60269-2-1, section 2) and the 16th edition of the
IEE Wiring Regulations (BS7671).

on
l

in
ec

om

• The fuse carriers are fitted with a ‘cam’ action for ease of removal

from the fuse base. The design ensures high contact pressure
between the fuse carrier contacts and the base contacts, with a
corresponding enhanced electrical performance level.

• Camaster Fuse Holders have a unique channel and guide

arrangement which prevents any tilting of the fuse carrier when it is
being inserted or removed, eliminating any likelihood of inadvertent
contact with live metal.
• Fixing screws to the fuse carrier are held in captive hinges,

providing ease of fixing and preventing loss during installation.
The hinges also act as pressure plates thereby reducing the contact
resistance between the fuse link tags and the carrier contact.
• Cable terminations fully meet the requirements of sub-clause 7.1.7

terminals of IEC60947: Part 1 Low Voltage Switchgear and
Controlgear.
• Camaster Fuse Holders, as standard, provide both bolted panel

and DIN rail mounting features. When DIN rail mounted all ratings of
fuse holder give equal height and depth above and below the DIN rail.
• Non removable full shrouding of live parts within the fuse base

provided by the use on hinged shields which cannot be omitted
during installation and are designed so that insertion of the fuse
carrier can only be made with them correctly positioned.
• Neon clip-in indicator accessories are available, the neon being lit

when the fuse link has operated. (Minimum system operation 90V).
• The fuse carrier has a marking label for ease of circuit identification.
• Ganging can be readily achieved by the use of standard

accessories, providing improved safety related to isolation and
protection of 2 and 3 pole electrical circuits.

SAFE LOC HRC Fuse Holders - Introduction

The patented Safeloc fuse holders provide a simple, safe range,
designed to accommodate the compact range of offset blade tag
fuse links to BS88 part 6 and IEC 60269-2-1 section IV.
The combination offers significant savings in volume and cost as
well as a reduction in fitting time and power loss. They provide a
safe and easy method of protecting a wide range of electrical
equipment such as lighting, heating, motor and control equipment
circuits.
The NNS fuse holder accomodates the NSD 2-32A range of
compact HRC fuse links whilst the slightly larger ENS fuse holder
accomodates the ESD 2-63A range of compact HRC fuse links.
Both holders are available in front connection or back stud
arrangements or combinations of these.

m

SAFELOC Fuse Holders are offered with the following features:

co

• Compact fuse link and fuse holder dimensions.
• Fuse holders employ a unique slide/snap carrier action for positive

nt

s.

and secure insertion and removal of the fuse link. This provides
positive, stress free fitting of fuse links and locks the fuse link in
position ensuring safe insertion and withdrawal from the base.
• The direct contact between fuse link blades and the plated base

ne

contacts provides low watts loss with increased reliability.
• The compact range of fuse links (i.e. NSD & ESD) fitted into the

po

Safeloc fuse holders, have an excellent ability to protect induction
motor circuits.

electric shock is obtained by fully insulated and shrouded fuse
holder base contacts.

• The fuse base utilises glass filled, high impact resistant,

thermoplastic polyester and incorporates a 35mm DIN rail
mounting facility as well as a single screw fixing.

Notes on Motor Circuits

All of the compact range of fuse links have an excellent ability to
protect induction motor circuits. The unique design of the Safeloc
Fuse Holders has enabled the design of dual rated fuse links which
offer protection for motor ratings up to 30kW.
Type gM fuse links for the protection of motor circuits have dual
rated characteristics. For example, an ESD63M100 has a
continuous current carrying capability of 63A, coupled with the time
current characteristic and the capabilities of a 100A fuse link.

Glossary of Terms

Cartridge Fuse
A fuse consisting of a current responsive
element inside a fuse tube with terminals on
both ends.

on
l

Class G Fuses
480V, 100,000 ampere 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 1 amp
through 60 amps.
Class H Fuses
250V and 600V, 10,000 ampere interrupting
rating branch circuit fuses that may be
renewable or non-renewable. These are
available in ampere ratings of 1 amp through
600 amps.
Class J Fuses
These fuses are rated to interrupt a minimum of
200,000 amperes AC. They are labelled
as “Current-Limiting”, are rated for 600 volts AC,
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 amps. These fuses are currentlimiting. However, they are not marked
“current-limiting” on their label since they do
not have a rejection feature.

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.

m

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.”

co

Classes of Fuses
The industry has developed basic physical
specifications and electrical performance
requirements for fuses with voltage ratings of
600 volts 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.

in
ec

Class CC Fuses
600V, 200,000 ampere 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¡º amp through 30 amps.

Fuse
An overcurrent protective device with a fusible
link that operates and opens the circuit on an
overcurrent condition.

s.

Breaking Capacity
(See Interrupting Rating)

Class T Fuses
An industry class of fuses in 300 volt and 600
volt ratings from 1 amp through 1200 amps.
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 200,000 amps RMS.

nt

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

ne

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.

Class R Fuses
These are high performance fuses rated ⁄Ω¡º600 amps in 250 volt and 600 volt ratings. All
are marked “Current Limiting” on their label
and all have a minimum of 200,000 amp
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.

po

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.

Class L Fuses
These fuses are rated for 601 through 6000
amperes, and are rated to interrupt a minimum
of 200,000 amperes AC. They are labelled
“Current-Limiting” and are rated for 600 volts
AC. 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.

om

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.

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.

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.
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.

Glossary of Terms

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.

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.

Semiconductor Fuses
Fuses used to protect solid-state devices.
See “High Speed Fuses”.

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.

265

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.

m

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.

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.

co

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.

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.

Withstand Rating
The maximum current that an unprotected
electrical component can sustain for a
specified period of time without the
occurrence of extensive damage.

s.

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.

available today, demonstrating the sort of applied

Previously, according to DIN 43 620, in most cases

have been applied together, reliability often has been
