For other power factor
values, the total clearing
integral can be calculat-
ed as a multiple of the
clearing integrals, the
correction factor K and
the correction factor X.
The ac voltage rating of Cooper Bussmann® fuses is given in
volts rms. Fuses tested to IEC are tested at 10% above their
rated voltage. British Style BS 88 fuses are tested at 5%
above its rated voltage. UL recognition tests are performed at
the rated voltage.

When fuses are connected in parallel it is recommended that
the applied voltage does not exceed 0.9 U (the rated volt-
age 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 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.
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.
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 maxi-
mum permissible load current.
Series Connection
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
Furthermore, it is important that a fuse should not be applied
in the non-continuous/dashed portion of the associated
time-current curve.
to 0.9 U (the rated voltage of the fuse).
N
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.
Mounting Guidance
The recommendations below have to be followed when
mounting a Cooper Bussmann fuse with end plate threaded
holes.
DC Operation
Depending upon the short-circuit time constant and the mag-
nitude 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 short-circuit currents
result in faster fuse openings and thus permit a fuse to be
operated at a higher dc voltage.

The Cooper Bussmann Paul P. Gubany Center in St.
Louis is certified by Britain’s prestigious ASTA
(Associated Short Circuit Testing Authority) to
perform short testing of its own devices designed to
operate to ASTA requirements which are closely tied
to IEC requirements. The Gubany Center is the only
testing facility available in North or South America
for this product certification.

Fig. 2: 70-100A
The Gubany Center has equipment capable of
generating 300,000A of current at 600Vac three-
phase, and 100,000A at 170Vdc, under carefully
controlled conditions. It offers a wider range of
current voltage and frequency configurations than
any other facility of its kind in the world, and is built
to exceed the short circuit capacity of today’s high
power electrical distribution systems.

Cooper Bussmann Named First in
Fuses by Readers of Plant
Services Magazine
Cooper Bussmann has been named as the vendor
offering the highest value in electrical fuses in a
recent fill-in-the-blank survey of nearly 40,000
qualified readers of Plant Services Magazine. A full
70 percent of survey respondents said Cooper
Bussmann was their number one choice. The
nearest competitor weighed in at only 7 percent. The
63 percent spread was the widest of all 63 product
categories, ranging from aerial work platforms to
welding equipment. According to Plant Services
editors, the products chosen are those “that deliver
the combination of functionality, durability and low
maintenance that add up to the lowest estimated
life-cycle cost”—those offering the very best value in
their product category.
