| A multipolar type circuit breaker has a plurality of breaker element assemblies corresponding to AC source pole number. Each assembly comprises a contact operating mechanism for ON and OFF operations of a movable contactor connected to a load side terminal with respect to a fixed contactor connected to a current source side terminal. A trip mechanism forms an electric current path between the movable contactor and the load side terminal an interlinks with the contact operating mechanism for releasing its normal ON position latch with respect to the movable contactor upon incoming of a excessive curent to arbitrarity trip ON state. The assemblies are housed in a single housing in a mutually parallel and aligning relation. The contact operating mechanisms in all assemblies are operated by a single handle extending transversely to them within the housing. The tripping operation of the trip mechanism in any of the assemblies is synchronously transmitted at a high speed to other assemblies through a single interlinking rod also extending transverse to all the assemblies and holds the handle at a neutral position between its ON and OFF positions. | ||||||
