Square Body – Flush End Contact

690V (IEC)

1000-4000A

The total clearing I

at power factor of 15% are given in the

electrical characteristics. For other volt-

ages, the clearing I

plying 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 loss-

es at load currents lower than the rated

current . The correction factor, Kp , is

given as a function of the RMS load cur-

rent, Ib , in % of the rated current .
