Yueqing Yijin Electronics Co., Ltd.
Beiyuan BB1-63 miniature circuit breaker accessories
MN undervoltage
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
When the main circuit voltage drops to (170V ± 5%), the product will activate and drive the circuit breaker to open; When the applied voltage is greater than 85% Ue, the product should be able to close. The applied voltage value should not exceed 110% Ue, and the undervoltage protection interval is: (35%~70%)Ue
