A shield structure on the line side of a circuit breaker has several adjacent channels for carrying ionized gases and cables electrically connected to a line terminal assembly. The shield structure has a main portion and a stepped portion which directs the channels and, thus, the cables and the ionized gases to the rear of the circuit breaker. The main portion has sidewalls, a top wall, and inner walls which form compartments, and which communicate with the walls of the circuit breaker to enclose a pole unit for each of the line terminal assemblies. In each compartment of the main portion of the shield structure, a hanging barrier is disposed between the entrances to the channels for the cables and those for the ionized gases, and cooperates with a flexible member associated with the line terminal assembly to separate the vented ionized gases from the cable line connection, and a hanging lug with an aperture, abuts a tube leading into the line terminal assembly to contain the ionized gases in an area between the barrier and the lug to direct the flow of ionized gases into the channels and to separate the gases from the cable connection. A second embodiment of the present invention has transverse channels for receiving the cables in the top of the circuit breaker.
A circuit interrupter for an electrical distribution system having a rear area, a line side with line terminal means and cable means connected to a power source, and a load side with load terminal means, comprising:
A device used in conjunction with a circuit interrupter having an interior, a rear area, a line side, and cable means electrically connected to terminal means on said line side of said circuit interrupter and which said circuit interrupter experiences a current interruption, ultimately resulting in the formation of ionized gases in said interior of said circuit interrupter, said device comprising:
