Yueqing Yijin Electronics Co., Ltd.
Shanghai Liangxin NDB1 small circuit breaker accessories
MX+OF passive shunt+auxiliary 110V~400V
The accessories of this series of circuit breakers are auxiliary functional components specially designed by our company for NDB1 series circuit breakers, which achieve remote tripping control and indication of the on/off status of the line
At 70%~110% of the rated control power supply voltage, the release should reliably operate to disconnect the circuit breaker. When the release is opened, 11 and 12 are connected, and the external safety signal light is on; When the release is closed, 11 and 14 are connected, and the external warning signal light is on; When the release is closed and the external button is connected, the mechanism of the release trips and drives the circuit breaker to trip and disconnect.
