Electrical Characteristics
Total Clearing I²t

K
The total clearing I²t at rated _1.0
voltage and at power factor
of 15% are given in the
electrical characteristics. For _0.5
other voltages, the clearing
I²t is found by multiplying by _0.3
correction factor, K, given as _0.2
a function of applied working
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.
