Notes:
(1) These fuses have only been tested at a rated maximum interrupting current of 44,000A RMS symmetrical due to test station limitations. All other fuses have a rated maximum interrupting
current of 50,000A RMS symmetrical.
(2) Current ratings shown above are achieved by using a parallel combination of two fuses (order two fuses). To facilitate equal sharing of the interrupting duty, the two fuses should be
resistance matched (±2%) and be mounted such that current paths to and from each fuses are symmetrical.
(3) Tabulated maximum total I
2
t values are at the nominal voltage of the fuse. Values for 17.2kV fuses at 15.5kV are reduced by approximately 12%, while values for 23kV fuses at 25.5kV are
increased by approximately 13%.
(4) Maximum total I
2
t values are reduced for currents below 50,000A. For example, at 10,000A, maximum total I
2
t values are approximately 15% less than the published values.
(5) Peak arc voltages quoted are for 50,000A currents at the rated maximum voltage listed. Reduced voltages and currents will reduce the peak arc voltage. Consult the factory for information.
