Catalogue numbers

Dimensions (mm) - Size 000

Dimensions (mm) - Size 230

Time-current curve - Size 000, 25 A to 250 A

Cut-off curve - Size 000, 25 A to 250 A

Total clearing I2t

The total clearing I2t at rated voltage and at a power factor of 15 percent 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 appear across the fuse during its operation as a function of the applied working voltage, Eg, (RMS) at a power factor of 15 percent.

Watts losses
Watts loss at rated current is given in the electrical characteristics. The curve allows the calculation of the watts 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 percent of the rated current.
