Yueqing Yijin Electronics Co., Ltd.
Beiyuan BB2A-63, BB2S-63 miniature circuit breaker accessories
MN2A undervoltage
The accessories of this series of circuit breakers are auxiliary functional components specially designed by our company for the Beiyuan BB2A series circuit breakers, which achieve remote tripping control and indication of the on/off status of the line
When the main circuit voltage drops to (170V ± 5%), the product activates and drives 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
