1.Overview
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.
Applicable place: Magnet switch is mainly used as 10kv substation outlet switches and 10kv three-phase AC electric power system,for closing and opening the load current, breaking an over-current and short-circuit current of line protection switch.
