Electric intensity

The voltage for electrical strength and power frequency sinusoidal is 2000V without breakdown and flash over when lasts 1minute

Overload Capacity

It can last 1 minute at the rated current of two times

Wave form Distortion

No additional waveform distortion

Protective function

it offers the protections against over voltage,over current,phase shortage and phase-sequence(The single-phase offers no protection against the phase shortage and phase-sequence)and mechanical failure

Response speed

≤1s(in the condition that the external voltage changes is 10%)
