DZ47 miniature circuit breaker accessories
MV overvoltage
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
When the main circuit voltage is (85%~110%) e, the release should be able to maintain long-term operation of the circuit breaker. When the voltage of the main circuit rises to 270V ± 5%, the release device combined with the circuit breaker should act to drive the circuit breaker to open.
