Product Description

General

ZW8-12 serues vacuum circuit breaker is high voltage outdoor switch-gear with rated voltage 12KV,three-phase AC50Hz,which is mainly useed for making and breaking load current, over-current,short-circuit current rural network, city network and miniature power system..The overall structure of this product is three-phase co-box type,three-phree- vacuum explosion chamber in the metal box,the performance is reliable and the insulation strength is higher by making use of SMC insulation material phase to phase insulation and to earthing.ZW8-12G is formed with ZW8-12 circuit breaker and isolation knife,called combined circuit breaker,may use for breaking switch.The operating device of this series product is CT23 spring loaded operation mechanism,divides ingo two kinds of motor operation operation and manuall operation.
