摘要： A circuit interrupter including a housing, separable main contacts within the housing, and an operating mechanism within the housing and interconnected with the contacts. An arc extinguisher assembly is disposed within the housing. Also provided within the housing is a slot motor assembly having a cavity region within which the contacts are substantially located. The slot motor assembly electro-magnetically interacts with current flowing between the contacts, and includes magnetic plates positioned in a slot motor housing. The slot motor housing has a tendency to move an arc existing between the contacts toward the arc extinguisher assembly. The slot motor assembly also includes an insulation member positioned within the cavity region and between the magnetic plates and the slot motor housing.

摘要： An improved circuit breaker and arc chute has a shield apparatus that includes a number of plate-like shield members that have elongated openings formed therein to receive portions of arc plates therethrough. The portions of the arc plates that pass through the shield member are received in receptacles of a support apparatus that supports the arc plates. The arc plates are themselves configured to retain the shield members against the support apparatus to protect the support apparatus from damage in the event of an electrical arc. Advantageously, the retention of the shield members between portions of the arc plates and portions of the support apparatus enables the shield members to be held in place without the use of adhesives or separate fastening systems.
