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. 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%. Power Losses Watts loss at rated cur- rent is given in the electri- cal characteristics. The curve allows the calcula- tion 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 . Cut-Off Current A fuse operation relating to short-circuits only. When a fuse operates in its current-limiting range, it will clear a short-cir- cuit 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.

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. Rated Current Rated current is given in amperes rms. Cooper Bussmann fuses can continuously carry the rated current. Melting Characteristic The melting char- acteristic shows the virtual melting time in seconds as a function of the prospective current in amperes rms. The fuses are spe- cially constructed for short-circuit pro- tection against high level fault currents. Loading and opera- tion of the fuse in the non-continu- ous/dashed section of the melt curve must be avoided. The curve can also be read as the real melting time as a function of the RMS value of the pre-arc current. Clearing Integrals The total clearing I 2t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I 2t is found by multiplying by correction factor, K, given as a function of applied work- ing voltage, Eg, (rms). 104 103 1 224 6 8 2 102 24 6 8 103 101 Prospective Current In Amperes RMS Virtual Pre-Arcing Time In Seconds 10–4 K 1.5 1.0 0.5 0.4 0.3 0.2 100 200 300 400 500 600 660 Eg 1.0 0.9 0.8 0.7 COS /H9272 X UL 1.4 1.2 103 200 300 400 500 600 660 Eg Kp 1.0 0.8 0.4 0.5 0.6 0.3 0.2 0.1 30 40 50 60 70 80 90 100% Ib

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. 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 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 buss-bar by means of nut and washer: Thread Torque (N•m)* Configuration Max Min 5⁄16” – 18, M8 25 20 3⁄8” – 16, M10 45 40 3⁄8” – 24 45 40 1⁄2” – 13, M12 65 50 1⁄2” – 20 65 50 *1 N•m = 0.7375 lb-ft 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 I t.I t is the melt- ing current corresponding to the time “t” of the overload dura- tion as read from the time-current curve of the fuse. The guidelines in the table below determine the acceptability of the selected fuses for a given Imax. Frequency of Occurrence Overloads (> 1 sec) Impulse Loads (< 1 sec) Less than once per month I max < 80% x It Imax < 70% x It Less than twice per week I max < 70% x It Imax < 60% x It Several times per day I max < 60% x It — 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 maxi- mum 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 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. Consult Cooper Bussmann for additional information and application assistance when fuses have to operate under dc conditions. Load Current Versus Conductor Cross Section Reduction of permissible load current when the conductor cross section is less than that given in IEC Publication 269-1 & 4 valid for Cooper Bussmann semiconductor fuses.

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. 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.

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 .
