Total Cleaning I²t
Arc Voltage
Power Loss
The total clearing I²t at rated voltage and at
power factor of 15% 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).
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%.
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.

Conditions for operation in service
Where the following conditions apply, fuses complying with this standard are deemed capable of operating satisfactorily without
further qualification.
Normal temperature: -5℃ to 40℃;
The altitude of the site of installation of the fuses does not exceed 2000m above sea level;
The air is clean and the relative humidity does not exceed 50 % at the maximum temperature of 40℃;
Higher relative humidities are permitted at lower temperatures, e.g. 90 % at 20℃;
Under these conditions, moderate condensation may occasionally occur due to variation in temperature.
For operation conditions other than above, please contact manufacturer.
