    摘要： A circuit interrupter includes a movable contact assembly having a movable contact, a stationary contact assembly, and an operating mechanism. The stationary contact assembly includes a conductor, a first stationary contact disposed on the conductor, and a second stationary contact disposed on the same such conductor proximate the first stationary contact. The first stationary contact has a first contact surface disposed a first distance from the conductor. The second stationary contact has a second contact surface disposed a second distance from the conductor. The second distance is smaller than the first distance. The operating mechanism is structured to move the movable contact assembly and cause the movable contact to engage or disengage from at least the first contact surface of the first stationary contact.

    摘要： A circuit breaker includes fixed and movable contacts, an operating mechanism including a movable arm carrying the movable contact, an arc chute including a plurality of spaced apart first and second arc plates, and a slot motor. A slot motor structure is disposed about the contacts and a portion of the movable arm. An insulative housing at least substantially covers and insulates the slot motor structure from the movable arm and contacts. The insulative housing includes a base and a pair of arms disposed therefrom. Each of the arms includes a first portion disposed proximate the first arc plates and a second smaller portion disposed proximate the second arc plates. A space extending from the first portion, not occupied by the second portion, is generally occupied by a portion of the second arc plates. The second portion forms a debris shield between the second arc plates and the operating mechanism.
