The VD4 medium voltage circuit-breakers use vacuum interrupters embedded in resin poles. 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.
