Vacuum Circuit Breaker Indoor High Voltage HVD11Y 1.14KV 630A VCB from Hubei JUCRO Electric

HVD11-1.14KV 630A permanent magnet vacuum circuit breaker mechanism is mainly used in 1140V or 660V three stage electrical distribution system. Vacuum circuit breakers can operate under a nominal current range, often breaking short-circuit current, more suitable for use in coal mine feed systems, consists of mining and high voltage flameproof distribution. Also can be used for large capacity engines to start infrequently.
