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, E g , (RMS).
