Electrical Characteristics
Total clearing I2t
Arc Voltage
Power Losses
The total clearing I2t at rated voltage and
at power factor of 15% are given in the
electrical characteristics. For other voltages, the clearing I2t is found by multiplying by correction factor, K, given as
a function of applied working voltage,
Eg, (RMS).
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%.
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.

The partial dotted curves
are for fuses designed to
give part range protection
(aR protection). Loading
or operation above the
curve indicated at A on
the curves must in general
be avoided. Please see
technical guidance
170K…
for further information.
Curves that are not dotted
are for fuses designed to
give full range protection.
