MNS electromagnetic voltage release device

Action characteristics:

The release and circuit breaker are combined together. When there is no voltage supply, the circuit breaker cannot be closed. When the supply voltage rises to 85% Ue, the circuit breaker is ensured to be closed normally; When the supply voltage drops to 35% Ue, the circuit breaker assembled with it is triggered to trip; When the supply voltage is zero or drops within the rated range, prevent the circuit breaker from closing again;
