Electrical Characteristics
Total Clearing I
The total clearing I
voltage and at power factor of
15% are given in the electrical
characteristics. For other volt-
ages, the clearing I
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 cur-
rent is given in the elec-
trical characteristics. The
curve allows the calcula-
tion 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, Ib,
in % of the rated current.
