Electrical Characteristics

Total Clearing I2t

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 .

Arc Voltage

This curve gives the peak
arc voltage, UL, which may 300 appear across the fuse
during its operation as a
function of the applied
working voltage, Eg, rms at a power factor of 100

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.
