Patent ID: 8138439

Claim:
An electrical switching apparatus comprising: a circuit interrupter comprising: a first housing including a number of first gas vents structured to provide a number of ionized gas flows, a number of first terminals, a number of second terminals, a number of separable contacts, each of said number of separable contacts being electrically connected between a corresponding one of said number of first terminals and a corresponding one of said number of second terminals, and an operating mechanism structured to open and close said number of separable contacts; and a limiter comprising: a second housing including a number of gas ports, a number of second gas vents and a number of gas channels, each of the number of gas channels being between a corresponding one of the number of gas ports and a corresponding one of the number of second gas vents, a number of third terminals, a number of fourth terminals, and a number of limiter devices, each of said number of limiter devices being electrically connected between a corresponding one of said number of third terminals and a corresponding one of said number of fourth terminals, wherein said limiter is coupled to said circuit interrupter, wherein each of the number of third terminals is electrically connected to the corresponding one of the number of second terminals, and wherein each of the number of gas ports is structured to receive a corresponding one of the number of ionized gas flows from a corresponding one of the number of first gas vents for passage through a corresponding one of the number of gas channels to the corresponding one of the number of second gas vents.
