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 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, K p , is given as
a function of the RMS load
current, I b , in % of the
rated current.
