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.

Circuit breaker with a front panel

Circuit breakers are configured with line terminal geometry that drives the current from a terminal input in a direction that can reduce electromagnetic forces and that can also or alternatively include an arc chute assembly that can reduce repulsive electromagnetic forces to improve the operating level of withstand current (Icw).

Cover apparatus

A debris barrier is for an electrical switching apparatus. The electrical switching apparatus includes separable contacts and an arc chute. The separable contacts generate debris when tripping open in response to an electrical fault. The arc chute has a plurality of splitter plates each having an edge portion and a distal portion located opposite and distal the edge portion. The debris barrier includes a first leg, a second leg, and a middle portion connecting the first leg and the second leg. The middle portion is coupled to one of the separable contacts. At least one of the first leg and the second leg has a first barrier portion and a second barrier portion extending therefrom. The first barrier portion is located proximate the distal portion. The second barrier portion extends from the first barrier portion toward the edge portion in order to redirect the debris toward the edge portion.

Electrical switching apparatus and debris barrier therefor

A thermal trip assembly is for an electrical switching apparatus. The electrical switching apparatus includes a housing, separable contacts enclosed by the housing, an operating mechanism for opening and closing the separable contacts, and a number of shunts. The thermal trip assembly includes a load conductor, a bimetal adapted to cooperate with the operating mechanism to open the separable contacts in response to a trip condition, and a bypass heater element structured to be electrically connected to the shunts. The bypass heater element directs the flow of electric current to at least partially bypass the bimetal.

Electrical switching apparatus and thermal trip assembly therefor

A multi-purpose mounting assembly is provided. The multi-purpose mounting assembly is structured to be disposed in an electrical switching apparatus housing assembly. The multi-purpose mounting assembly includes a body defining a first mounting assembly and a second mounting assembly. The first mounting assembly includes a first mounting construct. The second mounting assembly includes a second mounting construct. The first mounting construct is structured to support a first electrical component. The second mounting construct is structured to support a second electrical component.

Multi-purpose mounting for an electrical switching apparatus

Electrical switching apparatus and strain relief assemblies therefor are described herein. In one exemplary, non-limiting embodiment, a strain relief assembly includes a cover and a base, each of which include a number of grooves structured to receive a number of wires. Each groove has a first side and a second side, where the second side is located opposite the first side. Furthermore, located on the first side and/or the second side are a number of protrusions. The grooves and the protrusions serve to secure the number of wires within the strain relief assembly such that, if a force is applied to an end of the wire, the protrusions work to retain the wires with the assembly.

Electrical switching apparatus and strain relief assembly therefor

Front panel of a circuit breaker

Molded case circuit breakers (MCCBs) have an MCCB body with at least one switch printed circuit board (PCB) holding between 1-4 recessed switches. The switch PCB has a bottom primary surface and an opposing top primary surface and a cover residing over the switch PCB and attached to the MCCB case body so that an outer end portion of the 1-4 switches held by the switch PCB extends through the cover.

An electrical switching apparatus housing assembly for an electrical switching apparatus assembly is provided. The electrical switching apparatus housing assembly including a body assembly and a movable door member. The body assembly includes a number of outer sidewalls. The outer sidewalls define an enclosed space. The outer sidewalls include a top sidewall. The top sidewall includes a limited opening to the enclosed space. The movable door member is movably coupled to the top sidewall. The door member is movable between an open, first position, wherein the door member is not disposed in the limited opening, and a closed, second position, wherein the door member is disposed in the limited opening.

Hidden/sliding door system for field-installed accessory access

A circuit breaker including a pair of separable contacts and an arc chamber is provided. The separable contacts include a fixed contact having an upper surface. The arc chamber includes magnetic members disposed on either side of the separable contacts. The magnetic members have a lower surface below the fixed contact upper surface.

Arc chamber for bi-directional DC

An arc runner assembly for use in a circuit interrupter provides a pair of arc runners that are situated at opposite sides of a stationary contact of the circuit interrupter. If used in a DC application, the arc runner assembly is configured to communicate a positive DC arc along one of the arc runners in a first direction away from the stationary contact and is further configured to communicate a negative DC arc along the other arc runner in another direction away from the stationary contact. The arc runner assembly additionally includes a support that is electrically engaged with a conductor of the circuit interrupter on a surface opposite that on which the stationary contact is disposed. The improved arc runner assembly advantageously facilitates extinction of electrical arc and extinguishes both positive and negative DC arcs in a DC application.
