Product Overview

The disconnector is composed of the support frame, base, post insulators, contacts, and terminal pads. The post insulators and conductive parts are mounted on the base, with an included angle of 50° between the two post insulators. The base is fixed on the support frame, which is tilted at 25°. The support frame is equipped with a shaft connected to the operating mechanism. It can be fitted with a CS17G manual operating mechanism or motor-operated mechanisms such as CJ6.
