Electrical Characteristics

voltage and at power factor of

15% are given in the electrical

characteristics. For other volt-

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 dur-

ing its operation as a function

of the applied working volt-

age, Eg, (rms) at a power

factor of 15%.

Power Losses

Watts loss at rated current is

given in the electrical charac-

teristics. 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.
