ARC CHAMBER EMPLOYING A NUMBER OF GASSING INSERTS TO FORM A NUMBER OF GAS FLOW CIRCULATION PATHS AND ELECTRICAL SWITCHING APPARATUS INCLUDING THE SAME

摘要

An electrical switching apparatus includes separable contacts, an operating mechanism structured to open and close the separable contacts, and an arc chamber. The arc chamber includes a slot motor having a core and a housing with an opening therein, an arc chute, and a number of gassing inserts disposed in the opening of the housing. The number of gassing inserts and the housing are structured to form a number of gas flow circulation paths. The number of gas flow circulation paths are structured to drive an arc into the arc chute.
