Electrical Characteristics
Total Clearing I

t
The total clearing I
2
t at rated voltage and
at power factor of 15% are given in the
electrical characteristics. For other volt-
ages, the clearing I
2
t is found by multi-
plying 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 .
