Total Clearing I2t
The total clearing I2t at rated voltage and at power
factor of 15% are given in the electrical characteris-
tics. For other voltages, the electrical I2t is found by
multiplying by correction factor K, given as a func-
tion 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 func-
tion of the applied working voltage Eg (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 Kp, is given as a
function of the RMS load current lb, in % of the
rated current.
