Total Clearing I²t
The total clearing I²t at rated voltage and at power factor 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)
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%.
Power Losses
Watts loss at rated current is given 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.
