Yueqing Yijin Electronics Co., Ltd.
C9N miniature circuit breaker accessories
MV+MN overvoltage and undervoltage
The accessories of this series of circuit breakers are auxiliary functional components specially designed by our company for the C9N series circuit breakers
When the main circuit voltage is (85%~110%) Ue, the release should be able to maintain long-term operation of the circuit breaker. When the voltage of the main circuit rises to (280V ± 5%) or falls to (170V ± 5%), the release combined with the circuit breaker should act to drive the circuit breaker to open. Undervoltage protection interval: (35%~70%)Ue
