Electrical Characteristics of Trans-Guard
®
SX Fuses
Notes:
1. Designs have a 50,000 amps RMS. Symmetrical Rating (except 5A 17.2kV which was tested at 44kA maximum).
2. Fuses rated 75A and below are 2.25" in diameter. Higher ratings are 3.3" in diameter.
3. Tabulated Maximum Total I
2
t values are for currents of 50,000 amperes at the nominal voltage of the fuse. Fuses which have a Rated Maximum Voltage higher than their Nominal Voltage
Rating will have a higher I
2
t let-through when applied at voltages up to these higher values. For example, Maximum Total I
2
t values are increased by approximately 30% when 8.3kV fuses
are applied at 10kV and approximately 25% when 15.5kV fuses are used at 17.2kV.
4. Maximum total I
2
t values are reduced for currents below 50,000A. For example, at 10,000A, I
2
t values are approximately 15% less than the published values.
5. Maximum continuous currents at different ambient temperatures: These may be determined by derating the fuses by .2% per degree C over 60° C (for example at 80° C the derating would
be 20 x .2 = 4%, making the maximum continuous current of a 20 A fuse 22.5 x .96 = 21.6A) or rerating the fuses by .2% per degree C under 60° C (for example, at 40° C the rerating
would be 20 x .2 = 4%, making the maximum continuous current of a 20 A fuse 22.5 / .96 = 23.4A). The long time melting current of the fuses (approximately one hour and longer) due to
different ambient temperatures is the same as described above for “Maximum Continuous Currents”. See time current characteristics for melting characteristics in this time region.
6. Peak arc voltages quoted are for 50,000A currents at the rated maximum voltage listed. Reduced currents and voltages will reduce the peak arc voltage.
