Total Clearing I2t The total clearing I2 t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I2 t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (RMS).
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%.
Watts loss at rated current is given in
the electrical characteristics. The curve
allows the calculation 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 .
