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%.
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 correc-
tion factor, Kp, is given as
a function of the RMS load
current, Ib, in % of the
rated current.

t
The total clearing I
2
t at
rated voltage and at power
factor of 15% are given in
the electrical characteris-
tics. For other voltages, the
clearing I
2
t is found by mul-
tiplying by correction factor,
K, given as a function of
applied working voltage,
Eg, (rms).
