For conductor cross section according to IEC 60269-1, the fuses with a rated current higher than 125A must be derated. Please contact Bussmann for application assistance.

For other voltages, the clearing I[2] t 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%. ## **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 . **==> picture [455 x 118] intentionally omitted <==** **----- Start of picture text -----**
