Arc Voltage
This curve gives the peak
arc voltage, UL, which may
appear across the fuse dur-
ing its operation as a func-
tion of the applied working
voltage Eg, (rms) at a
power factor of 15%.

voltage and at power factor
of 15% are given in the elec-
trical characteristics. For
other voltages, the clearing

allows the calculation of
the power losses at load
currents lower than the
rated current. The correc-
tion factor, Kp, is given as
a function of the RMS load
current, Ib, in % of the
rated current.
