Yueqing Yijin Electronics Co., Ltd.
AB 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 A * * and other series circuit breakers, which achieve remote tripping control and indication of the on/off status of the line
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
