Zn12 (Zn72) 40.5 Indoor Ac 50hz Hv Vacuum Circuit Breaker

In order to keep pace with the never-ending demands of customers, we are involved in exporting, manufacturing and supplying a superior quality collection of ZN12 (ZN72) 40.5 Indoor AC 50HZ HV Vacuum Circuit Breaker in Tianjin, China. ZN12 (ZN72) -40.5 Indoor Vacuum Circuit Breaker 35KV three-phase AC 50HZ applied to power system, the circuit breaker for the ceramic structure, using the longitudinal magnetic field contacts, is small, the proliferation of breaking arc generated when current distribution in the contact on the same local melting phenomenon does not occur, but also has a low arc energy voltage (20-200V) and low chopping current (4-5A), and operate with high reliability organizations.

Adopt solid insulation structure, use of advanced solid epoxy sealing technology, the first time, the vacuum interrupter. A leading electrical circuit. insulation and other support to become an integrated combination of solid seal pole. Successfully from a fundamental solution of the vacuum breaker gas environment, tolerance issues, make it more broad. Integrated solid-pole closure of the fluent use of a self-ventilation technology, cleverly solved the structure of solid insulation caused by heat dissipation.
