Exhaust arc gas manifold

摘要

An industrial rated molded case circuit breaker fitted with an exhaust arc gas manifold arranged over ventilation slots of the circuit breaker and disposed at a line end thereof to redirect the arc exhaust gases exiting the ventilation slots. The exhaust arc gas manifold is fixedly attached to the circuit breaker to prevent an electric fault from occurring between the different phases of a multi-phase electric power distribution system connected to the line end of the circuit breaker. An electric fault is further prevented between the exiting arc gases and the line terminals attached to the circuit breaker thereof.
