ARC-PROOF MOLDED CASE CIRCUIT BREAKER

摘要

An industrial rata multi-phase molded case circuit breaker is fitted with an exhaust gas barrier and line lug cover at the line end thereof to redirect the arc exhaust gases exiting from the line end. An electric circuit is prevented between the different phases of a multi-phase electric power distribution system connected with the line end of the circuit breaker. Furthermore, an electric circuit is further prevented between the exiting arc exhaust gases and the electrical distribution bus bars to which the multi- phase electric circuit breaker is connected.
