Product Description

Timetric Indoor Solid Sealed Vacuum Circuit Breaker Introduction

Indoor Solid Sealed Vacuum Circuit Breaker is a three-phase AC 50Hz, rated voltage of 12kV indoor switching equipment, can be used for industrial and mining enterprises, power plants and substations, electrical facilities for control and protection, and suitable for frequent operation places. Using the integration of the operating mechanism and the circuit breaker body, the design can be used as a fixed installation unit, but also can be equipped with a special propulsion mechanism, to form a handcart unit for use. The main loop part can be used as a whole solid sealing pole, in order to achieve the circuit breaker miniaturization, high reliability, maintenance-free, can be used with KYN28A-12(GZS) and other middle mobile switchgear, fixed type can also be used for XGN series fixed type switchgear.
