Beiyuan BB1-63 miniature circuit breaker accessories

MNs electronic voltage loss
The accessories of this series of circuit breakers are auxiliary functional components specially designed by our company for the Beiyuan BB1 series circuit breakers, which achieve functions such as line working status indication and trip alarm
The combination of a release and a circuit breaker triggers the release of the assembled circuit breaker when the supply voltage drops to 35% Ue; When the supply voltage rises to 85% Ue, ensure that the circuit breaker closes normally; When the supply voltage is zero or drops within the rated range, the circuit breaker opens.
