Yueqing Yijin Electronics Co., Ltd.
EA9/CDB9/NDB2 miniature circuit breaker accessories
MV+MN three-phase four wire overvoltage and undervoltage
The accessories of this series of circuit breakers are auxiliary functional components specially designed by our company for Schneider EA9, Delixi CDB9, and Liangxin NDB2 series circuit breakers, achieving remote trip control and on/off status indication 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
