Electrical Characteristics
Total Clearing I
2
t
The total clearing I
2
t at
rated voltage and at power
factor of 15% are given in
the electrical
characteristics. For other
voltages, the clearing I
2
t is
found 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 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, K
p
, is
given as a function of the
RMS load current, I
b
, in %
of the rated current.
