Electrical characteristics

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 volt- ages, the clearing I2t is found by multiplying by correction factor, K, given as a function of applied working voltage, Eg, (RMS).

2) FM, FMM

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.

2) ET, FE, EET, FEE, FM, FMM

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.
