Electrical
Characteristics
Total Clearing I²t
The total clearing I²t at
rated voltage and at power
factor of 15% are given in
the electrical
characteristics. For other
voltages, the clearing I²t is
found by multiplying by
correction factor, K, given
as a function of applied
working voltage, Eg, (rms).
