A device for reversed operation of a first handle is provided. The first handle is of a circuit breaker. The device includes a housing that is attachable to the circuit breaker, and a lever that is rotatably attached to the housing. The lever includes a body, and an arm and a second handle each extending away from the body. The lever is movable in a first direction relative to the housing in response to a force at the second handle, such that when the housing is attached to the circuit breaker and the lever moves in the first direction relative to the housing, the first arm is configured to press against and move the first handle of the circuit breaker in a second direction relative to the housing, the second direction being away from the first direction.

An electrical contact apparatus having low silver content and defined thickness and length geometry. The electrical contact apparatus has a contact body made of a silver-containing alloy having SC&#x2264;60 wt. %, and having L/T&#x2265;5.4, wherein L is a longest contact length dimension of the contact body, T is a maximum contact thickness dimension of the contact body, SC is the silver content in wt. %, and L/T is a contact dimension ratio. Electrical contact assemblies, circuit breaker electrical contact subassemblies, and methods of operating a circuit breaker electrical contact subassembly are disclosed, as are other aspects.

Low-silver, low-profile electrical contact apparatus and assembly

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.
