AC 690V 2000A Low Voltage Circuit Breakers Three Pole Main Breaker Switch 50Hz

Product Introduction of AC 690V 2000A Low Voltage Circuit Breakers Three Pole Main Breaker Switch 50Hz

TANW1 series intelligent universal circuit breaker (hereinafter referred to as circuit breaker) is a new generation developed by our company, adopting advanced technology. It is suitable in distribution network (4 pole is suitable in 3-phase-4-wire or 3-phase-5 wire system) with AC 50Hz, rated voltage 400, 600V, rated current 630-6300A, for distribution and protecting circuit and power unit from the faults of overload, undervoltage, short circuit, single phase ground. The circuit breaker has a function of intelligent protection, accurate selective protection, to improve power distribution reliability avoiding unnecessary outage.

The circuit breaker conforms to international and national standards of IEC60947-2, GB14048.2

The circuit breaker has passed China Compulsory Product Certification——CCC Certification issued by China Quality Certification Center (CQC)
