Abstract:

A circuit breaker includes an enclosure with a first side and a second side opposite and distal from the first side. A number of separable contacts are enclosed by the enclosure. An operating mechanism is structured to open and close the separable contacts. A plurality of terminals are electrically interconnected with the number of separable contacts. The terminals protrude through the second side of the enclosure. A number of phase barrier apparatus is disposed on the second side of the enclosure. Each of the number of phase barrier apparatus includes a plurality of separate phase barrier members, each of which is disposed about a corresponding one of the terminals, and a number of interlocking members. Each of the number of interlocking members interlocks with an adjacent pair of the separate phase barrier members.

US Classification:

335 23, 335 35, 335167

Abstract:

A magnetic trip mechanism is provided for an electrical switching apparatus. The magnetic trip mechanism includes a magnetic member, an armature having opposing first and second ends and first and second sides, an armature restraint and a biasing element. The armature moves among first and second positions corresponding to separable contacts of the electrical switching apparatus being tripped open and closeable, respectively. The armature restraint includes first and second portions. In the first position, the first side of the armature engages the magnetic member. In the second position, the second side of the armature engages the second portion of the armature restraint. The armature restraint and the biasing element comprise a sub-assembly, which is removably coupled to the magnetic member. After being removably coupled to the magnetic member, the biasing element is chargeable to bias the armature away from the first position toward the second position.

Abstract:

A heater assembly is provided for an electrical switching apparatus. The heater assembly includes a heater element and an elongated bimetal. The heater element includes first and second ends, an intermediate portion disposed therebetween and an aperture disposed proximate the first end. The elongated bimetal includes opposing first and second ends, and is movable between first and second positions corresponding respectively to the separable contacts of the electrical switching apparatus being closeable, and to the first end of the elongated bimetal cooperating with a trip bar to cause an operating mechanism to open the separable contacts. The second end of the elongated bimetal is coupled to the intermediate portion of the heater element. When the elongated bimetal is disposed in the first position, the first end of the elongated bimetal extends beyond the upper surface of the first end of the heater element into the aperture of the heater element.

US Classification:

200401, 335 35, 335173

Abstract:

A push-to-trip assembly is provided for an electrical switching apparatus, such as a circuit breaker. The push-to-trip assembly includes a push-to-trip actuator having first and second ends and being movable among a first position corresponding to the circuit breaker separable contacts being closeable, and a second position corresponding to the second end cooperating with a trip bar to cause the circuit breaker operating mechanism to trip open the separable contacts. The first end is accessible from the exterior of the housing to actuate the push-to-trip actuator from the first position to the second position. A biasing element biases the push-to-trip actuator away from the base toward the first position. At least one cover stop of the push-to-trip actuator engages a corresponding portion of the housing cover to stop movement of the push-to-trip actuator. An overtravel restraint proximate the second end of the push-to-trip actuator restrains movement of the trip bar.

H01H 71/02

Abstract:

A molded case circuit interrupter advantageously employs a circuitry component that is situated adjacent a rear exterior surface of the molded case of the molded case circuit interrupter. Previous circuit interrupters have sometimes employed a non-conductive backsheet of a nominal thickness of 0.062 inches that was adhered to the rear surface of the molded case circuit interrupter in order to electrically isolate screws, posts, and the like that were mounted to and that were exposed on the rear portion of a molded case thereof. The disclosed and claimed concept provides a circuitry component in place of or in addition to the back sheet, with the circuitry component including flexible ribbons having electrical conductors that extend through holes formed in the molded case and that are electrically connected with electronic components that are situated within the interior of the molded case.

Abstract:

A guide member is for an electrical switching apparatus. The electrical switching apparatus includes a primary cover, a secondary cover structured to move between a closed position and an open position, a first printed circuit board, a second printed circuit board spaced from the first printed circuit board, and a cable member electrically connecting the first and second printed circuit boards. The guide member includes a body having a base coupled to the primary cover, a ramp engaging the cable member when the secondary cover is in the closed position, the ramp having first and second opposing end portions, the first end portion extending from the base, and a number of guide portions each extending from the ramp and engaging the cable member when the secondary cover moves between the closed position and the open position in order to minimize twisting and folding of the cable member.
