Medium voltage vacuum circuit-breakers 12…24 kV – 630…3150 A – 16…40 kA. The new VD4 is a synthesis of the renowned technology in designing and constructing vacuum interrupters embedded in resin poles and of excellence in design, engineering, and production of circuit-breakers. 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. The ABB 630A 20kA VD4 VCB is typically used for protecting electrical circuits in industrial and commercial installations
