Electrical Characteristics

Total Clearing I2t

The total clearing I2t at rated

voltage and at power factor

of 15% are given in the elec-

trical 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

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.
