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%.

rated voltage and at power
factor of 15% are given in
the electrical characteris-
tics. For other voltages, the
clearing I

tiplying by correction fac-
tor, K, given as a function
of applied working voltage,
Eg, (rms).
