Arc Voltage
This curve gives the peak arc
voltage, U L , which may
appear across the fuse dur-
ing its operation as a function
of the applied working volt-
age, E g , (rms) at a power
factor of 15%.
Power Losses
Watts loss at rated current is
given in the electrical char-
acteristics. The curve
allows the calculation of the
power losses at load cur-
rents lower than the rated
current. The correction fac-
tor, K p , is given as a func-
tion of the RMS load cur-
rent, I b , in % of the rated
current.
