Electrical Characteristics

Total Clearing I2t The total clearing I2t at rated voltage and at power factor of 15% are given in the electrical characteristics. For other volt- ages,the clearing I2t is found by multi- 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 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 .
