VD4 medium voltage circuit breakers use vacuum interrupters embedded in the poles. This construction method makes the poles particularly sturdy and protects the interrupter from shocks, dust and condensation. VD4 circuit breakers are the best choice for the majority of modern electricity distribution applications and are used in transformer and distribution substations to control and protect motors, transformers, capacitor banks and for protecting cables.
