An arc shield apparatus for an electrical switching device. Arc shield apparatus includes a body having an abutting portion including a first side configured to abut against a lateral side of a contact arm of an electrical switching device, and a second side opposite from the first side, an aperture passing between the first and second side, the aperture configured to receive a spring tab of the contact arm therein, and an arc shield including a first shield portion extending from the first abutting portion, the first shield portion including a first contact surface configured to abut against a contact arm edge, and a second shield portion configured to shield at least some of the spring tab and spring hook. Shielded contact arm assemblies and methods of protecting a contact arm of an electrical switching device during an arcing event, are disclosed, as are other aspects.

Contact arm shields, shielded contact arm assemblies, and contact arm protection methods

A slot motor apparatus for a circuit breaker is disclosed. The slot motor has first and second legs connected by a thin web, and an extending portion extending rearward from the rear faces of the legs. Slot motor-arc plate assemblies having an arc plate assembly received at least partially overtop of the extending portion are also disclosed, as are assemblies having the arc plate assembly received very close to the rear faces of the slot motor legs. Circuit breakers, slot motor-arc plate assemblies, slot motor covers, and methods of operating the slot motor-arc plate assemblies are disclosed, as are other aspects.

Slot motor, slot motor cover, slot motor&#x2014;arc plate assembly, and methods of operation

An electrical contact is disclosed. The electrical contact includes a first element of a first material having one or more aperture, and a second element of a second material, the second element being positioned in at least one aperture of the one or more aperture of the first element, wherein the second material is different from the first material. Electrical contact devices, assemblies, and methods are provided, as are other aspects.

Electrical contact apparatus, assemblies, and methods

Certain exemplary embodiments comprise a bimetal restraint adapted to restrain a bimetal of a circuit breaker from deformation beyond a predetermined threshold during a short circuit event. In certain exemplary embodiments, the bimetal restraint can be adapted to act as a shunt during the short circuit event to transfer electrical energy from an electrical energy source to a load side of the circuit breaker.

Devices, systems, and methods for shunting a circuit breaker

Certain exemplary embodiments comprise an electrical bypass conductor adapted for installation in a circuit breaker. The electrical bypass conductor can be adapted to be operatively electrically coupled to a load side of the circuit breaker. The electrical bypass conductor adapted to transfer electrical energy from a source of electrical power to the load side of the circuit breaker during a short circuit event.

Certain exemplary embodiments comprise a circuit breaker mounting plate that can comprise a prong adapted to receive a clip. The prong can define a first longitudinal axis that extends in a first direction and in an opposing second direction. The prong can be adapted to receive a spring. The clip can comprise a latch. The latch can be adapted, via the spring, to releasably attach a circuit breaker to the circuit breaker mounting plate.

System and method for mounting a breaker

Certain exemplary embodiments comprise a device comprising: a trip mechanism adapted to engage an operating mechanism of an alternating current circuit breaker, said trip mechanism comprising: a bi-metal element arranged lengthwise into a first end zone, a central zone, and a second end zone, a load bus coupled to said first zone, said second end zone adapted to engage an armature latch that is adapted to trip on operating mechanism of the circuit breaker; and an electromagnetic element coupled to the load bus.

Systems, methods, and device for actuating a circuit breaker

An improved magnetic armature for magnetically activated circuit breakers. The armature being configured to provide a consistent engagement length between the armature and the contact operating mechanism of a circuit breaker. The armature also being configured to reduce the air gap distance between the armature and the magnetic yoke of a circuit breaker.
