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.
