Yueqing Yijin Electronics Co., Ltd.
DZ47 miniature circuit breaker accessories
MNs electromagnetic voltage loss
The accessories of this series of circuit breakers are auxiliary functional components specially designed by our company for DZ47-60 (C45), NB7, DZ158-125 (NC) and other series of circuit breakers
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;

product overview
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;
