Product Description

Good quality 11KV 630A vacuum circuit breaker with factory price

General Description
ZW8-12 Series outdoor high voltage vacuum circuit breaker is main switch equipment of rated voltage 12KV, three phases AC50Hz system, to switch on/off loading current, over-current, and short circuit in rural or urban power network. The structure of breaker is of three-phase assembled in a tank, three-phase vacuum arc-extinguishing chamber enclosed in metal tank, insulation material between phases and phase to each made of SMC, reliable performances, and high insulating strength.

ZW8-12G consists of ZW8-12 breaker and isolator, called combined breaker, can be used as sectionalizer.

The operating mechanism for this series breaker is CT23 spring charging mechanism, motor or hand operating type.

Application and feature

It is equipped with CT23 type spring energy-stored operating mechanism. Energy-stored, opening and closing can be achieved by motor or by manual.

Applying ambient conditions

Ambient temperature: The max, temperature should be+40 degrees. The mix. temperature The height above sea level should be no higher han 1000m.

Wind preesure should be on more than 7000Pa it isequivalent to wind speed of 34m/s The air filthy should be win in III degree. Frequently violent vibration should be forbidden.
