Total Clearing I 2 t
The total clearing I 2 t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other voltages, the clearing I 2 t is found by multiplying by correction factor, K , given as a function of applied working voltage,
E g
, (RMS).
Arc Voltage
This curve gives the peak arc voltage,
U
L
, which may appear across the fuse during its operation as a function of the applied working voltage, E g
, (RMS) at a power factor of 15%.

Power Losses
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, K p
, is given as a function of the RMS load current, I b
, in % of the rated current .
