Electrical Characteristics
Total Clearing I²t
The total clearing I²t at rated 1.5
voltage and at power factor
K
of 15% are given in the elec- ^1.0
trical characteristics. For
other voltages, the clearing
I²t is found by multiplying by ^0.5
correction factor, K, given as
a function of applied working ^0.3
voltage, Eg, (rms).

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