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%.
Total Clearing I2t:
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).

Power Losses:
Watts loss at rated current is
given in the electrical char
acteristics. 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.
