VACUUM CIRCUIT BREAKER

Introduction

Rated voltage 12kV ZW8-12 series vacuum circuit breaker three-phase AC 50Hz outdoor high voltage switch equipment, mainly used for breaking closing rural network, city network and small-scale power system load current, overload current, short circuit current. The overall structure of the product for three-phase box-type. Type three-phase vacuum interrupter placed in a metal box, the use of SMC insulating materials and white insulation and ground insulation, reliable performance, high dielectric strength.

ZW8-12G is formed by the ZW8-12 circuit breaker and isolating switch combination, a combination of circuit breakers can be used as the disconnect switches.
