Assignee:

Eaton Corporation - Cleveland OH

International Classification:

H01H 9/30
H01H 33/20

US Classification:

335201, 218148

Abstract:

A circuit breaker includes a conductor, a fixed contact connected to the conductor, and an arc runner disposed on the conductor adjacent the fixed contact. The arc runner includes a first portion abutting the fixed contact and a second portion disposed in a recess of the circuit breaker housing. The arc runner is adapted to draw an arc from the fixed contact. A circuit breaker operating mechanism cooperates with a movable contact for opening and closing the fixed contact and the movable contact. An arc chute is adjacent the arc runner. A trip unit cooperates with the operating mechanism to trip open the fixed and movable contacts.

International Classification:

US Classification:

Abstract:

A solenoid type magnetic trip assembly for a molded case circuit breaker includes an armature biased against an adjustable stop by a tension spring to set the initial gap for the magnetic trip, so that the spring bias remains constant for the full range of the initial gap. The armature includes an elongated armature element mounted by a frame to slide longitudinally along a pair of guide rails. The frame defines a trip surface axially aligned with the elongated armature element which engages a trip arm on a trip bar to trip the circuit breaker in response to a predetermined level of overcurrent. A bimetal providing a thermal trip function is cantilevered from a support spaced from the trip bar by the armature, but has a terminal portion at the free end projecting toward the trip bar and through which the elongated armature element of the armature extends. A radially enlarged slug on the free end of the elongated armature element of the armature is subjected to a magnetic force opposite to the force generated by load current tending to pull the armature into the solenoid coil. This opposing force increases as the initial gap increases, placing the slug closer to the magnetic frame, so that a greater range of trip currents can be selected despite limited room for armature travel.

Abstract:

A guard assembly is for an electrical enclosure. The electrical enclosure includes a housing, an electrical switching apparatus, and a handle. The guard assembly includes: a shaft including a first end and a second end, the first end being structured to be coupled to the handle, the second end being structured to be coupled to the electrical switching apparatus; and a sleeve assembly structured to move between a retracted position and an extended position, the sleeve assembly including a sleeve member, the sleeve member including: a base located proximate the first end of the shaft, and a cover portion extending from the base toward the second end of the shaft, the shaft extending at least partially through the cover portion. Responsive to the sleeve assembly moving from the retracted position toward the extended position, the sleeve member moves away from the second end of the shaft.
