A surge protection device has a housing that is formed from a first lateral portion, a middle portion, and a second lateral portion that are connected together with a plurality of fasteners. The surge protection device includes an electronic apparatus having a neutral wire and further includes a housing that advantageously includes a strain relief that causes the neutral wire to frictionally engage the housing with sufficient friction to resist a predetermined tension applied to the free end or other portion of the neutral wire at the exterior of the housing from damaging an electrical connection between the neutral wire and a circuit board within an interior region of the surge protection device.

Surge protection device

A circuit breaker assembly includes a circuit breaker including a housing and a handle extending from the housing, with the handle being movable between an on position and an off position. The assembly includes a handle mechanism connected to the housing of the circuit breaker. The handle mechanism includes a base, a slider slidably connected to the base and including first and second spaced apart arms with the handle of the circuit breaker at least partially between the first and second arms, and a spring on the slider. The slider is movable between a first position with the handle in the on position and a second position with the handle in the off position. The handle engages the spring with the handle in the on position and the slider in the first position.

A transfer assembly is for an electrical switching apparatus. The electrical switching apparatus has a first housing, separable contacts internal the first housing, and an operating handle having an ON position and an OFF position. The transfer assembly includes a rotary handle, a number of transfer components each structured to cooperate with the rotary handle, one of the transfer components being structured to engage the operating handle in order to allow the rotary handle to move the operating handle between the ON position and the OFF position, and a support assembly. The support assembly includes a second housing and a support member coupled to and located internal with respect to the second housing, the second housing being structured to be coupled to the first housing, the rotary handle being coupled to the second housing. Each of the transfer components is coupled to the support member.

A rotary motion switching apparatus is usable with a circuit interrupter and employs an attachment system in order to resist removal of the rotary motion switching apparatus from the circuit interrupter. The attachment system has three connectors that are engaged with an exterior surface of a housing of the circuit interrupter. The portions of the housing that are engaged by the three connectors are pre-existing portions of the exterior surface of the housing of the circuit interrupter.

Rotary motion switching apparatus usable with circuit interrupter

A rotary motion switching apparatus is usable with a circuit interrupter and employs an attachment system having a pair of connectors that are received in a pair of openings formed in a housing of a circuit interrupter and that are affixed to the housing within the openings in order to resist removal of the rotary motion switching apparatus from the circuit interrupter. The openings are pre-existing in the housing of the circuit interrupter and are provided to enable access by tools with terminals of the circuit interrupter to which load wires and the like are connectable. The connectors thus secure the rotary motion switching apparatus to the circuit interrupter by using openings that are already formed in the circuit interrupter and thus the rotary motion switching apparatus is usable without requiring a modification to the housing or to the molds that are employed to form the housing.

A rotary motion switching apparatus is usable with a circuit interrupter that is situated in a NEMA box or other box and employs an attachment system. An access port that is formed in a wall of the NEMA box or other box permits a shaft having a handle at an end thereof to be connected with the rotary motion switching apparatus. The rotary motion switching apparatus includes a universal joint on a rotational component that enables operation of the handle and shaft without binding on the wall of the NEMA or other box even if the access port in the box is offset from an axis of rotation of the rotational component.

A transfer assembly is for a switching assembly mounted in an electrical enclosure. The switching assembly has an electrical switching apparatus, a shaft, and a handle member coupled to the shaft. The electrical switching apparatus is structured to move between an ON position and an OFF position. The transfer assembly includes a body structured to be coupled to the electrical switching apparatus, and a cam assembly structured to move between a FIRST position and a SECOND position. The cam assembly includes a rotary member coupled to the body and structured to be coupled to the shaft, and a driving member cooperable with the rotary member. When the cam assembly moves between the FIRST position and the SECOND position, the driving member drives the electrical switching apparatus between the ON position and the OFF position.
