ZW43-12 permanent magnet outdoor MV vacuum circuit breaker 12KV HV VCB

KEY WORDS:High pressure vacuum switch

DETAILS

ZW43-12(G)/M630-20 series permanent magnet outdoor vacuum circuit breaker is three phase, rated voltage 12kv,AC 50HZ outdoor high-voltage VCB. Magnet switch is mainly used as 10kv /11KV /12KV substation outlet switches and  three-phase AC electric power system.

Magnetic switch is consider of three parts: the vacuum switch body, single stable permanent magnetic actuator and intelligent controller, it has a wide range of complex and flexible action program setting mode, with high reliability and security is with control and protection functions of the new"mechatronics" smart high-voltage switchgear.

Product Description
