Product Description

Yueqing OEM 3 phase automatic high voltage circuit breaker

Product Structure

ZW43-12(G)/M630-20 series permanent magnet outdoor vacuum circuit breaker is three phase, rated voltage 12kv,AC 50HZ outdoor high-voltage switchgear. 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.Breaker in line with GB1984-2003 (HIGH-VOLTAGE AC CIRCUIT BREAKERS), DL/T402-2007(HIGH-VOLTAGE AC CIRCUIT BREAKERS ORDERING TECHNOLOGY) and DL/T403-2000(12KV-405 HIGH-VOLTAGE VACUUM CIRCUIT BREAKER ODERING TECHNOLOGY) and other technical standards.

Product feature

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 hifh reliability and securitym is with control and protection functions of the new"mechatronics" smart high-voltage switchgear.
