Indoor Vacuum Circuit Breaker VD4

Description

The VD4 are a synthesis of the renowned technology in designing and constructing vacuum interrupters embedded in resin poles, and of excellency in design, engineering and production of medium voltage circuit - breakers. Embedding the interrupter in resin makes the circuit - breaker poles particularly sturdy and protects the interrupter against shocks, accumulation of dust and humidity. The vacuum interrupter houses the contacts and makes up the interrupting chamber.
