Abstract: A terminal connector assembly is provided for an electrical switching apparatus, such as a circuit breaker. The terminal connector assembly includes an electrically conductive member having opposing connecting and terminal portions, and a housing having a divider. The connecting portion is electrically connected to a power conductor of the circuit breaker. The divider includes first and second sides and an aperture extending therebetween. A plurality of walls extend perpendicularly outwardly from the first side of the divider to form a cavity, and a plurality of projections extend outwardly from the second side of the divider to engage and align the housing and the electrically conductive member with respect to the molded casing of the circuit breaker. The connecting portion of the electrically conductive member extends through the aperture of the divider and outside of the housing. The remainder of the electrically conductive member is disposed within the cavity.

Abstract: A circuit breaker includes a molded housing having a base and a cover forming a recess. A cylindrical steel pivot pin is disposed in the recess of the housing. Fixed and movable separable contacts are disposed within the molded housing. An operating mechanism is disposed within the molded housing for moving the separable contacts between an open position and a closed position. The operating mechanism includes a cradle having a latch portion and a generally U-shaped pivot portion which pivotally engages the cylindrical steel pivot pin. A trip mechanism cooperates with the operating mechanism to trip open the separable contacts. The trip mechanism includes a portion which engages the latch portion of the cradle when the separable contacts are in the closed position.

Abstract: A whole house surge protector is provided in a single unit in association with a 4-wire wiring system with surge suppression between each of two hot conductors and respective neutral and ground conductors and also between the two hot conductors. The unit is in an insulating housing securable merely by a threaded nipple directly with a load center for protection on a multiplicity of circuit branches.

Abstract: A multiple outlet receptacle, such as one having four outlets in respective quadrants, is provided with a surge suppression circuit including a metal oxide varistor edgewise between the front and back of the device, other electronic elements, including dual status indicators, connected with an outer ring like contact plate and secured within portions of the insulating housings. Features for compactness and ease of assembly are provided. A pilot light indicator may alternatively be provided in receptacles without a surge suppressor utilizing some of the same components and assembly features.

Abstract: A multiple outlet locking receptacle has a molded insulating body which includes a housing portion and a mounting flange portion formed integrally therewith. The housing portion has a front face thereon. The receptacle includes multiple groups of internal contact elements disposed in the housing portion of the body rearwardly of the front face thereon. The multiple groups of contact elements define multiple electrical outlets adapted for receiving multiple outlet plugs. Multiple arrays of plug blade receiving apertures are defined in the front face of the receptacle body housing portion. The multiple arrays of apertures are aligned with the multiple groups of internal contact elements and have arcuate configurations for accommodating insertion of the blades of the multiple outlet plugs through the apertures into electrical contact with the internal contact elements and then rotation of the blades relative to the internal contact elements into locking relation therewith.

Abstract: The pivot shaft which couples the contact arm to the side support plates of a molded-case type circuit breaker is provided with a pair of spacer members that hold the contact arm in precise centered position relative to the support plates and prevent the contact arm from shifting laterally along the pivot shaft during trip and reset operations of the circuit breaker. The movable contact thus swings along a fixed predetermined arcuate path when the circuit breaker is tripped and subsequently reset. The toggle assembly is also simplified and reduced in size and cost by employing a single, upper toggle link and pivot shafts that are each anchored in place by an integrally-formed shoulder at one end and a force-fitted lock washer at the other end.

Abstract: A circuit interrupter characterized by a multipole circuit breaker having line and load terminals and conductor means extending between the terminals for each pair of pole terminals, separate pairs of contacts serially connected in the conductor means, receiver means for sensing a control signal from an external source and sending a corresponding power signal to an operator means to effect opening of one of the pair of contacts.

Abstract: A circuit breaker structure having improved insulation means between the conductors which support the stationary and movable contacts to reduce or eliminate arc restriking conditions.

Abstract: A circuit breaker interlocking mechanism characterized by a pair of circuit breakers connected to different power supply sources in comprising a locking member pivotally mounted between the circuit breakers for preventing one circuit breaker from being actuated when the other is in a preselected operating position.

Abstract: A circuit breaker having an improved compact thrust transmitting spring for opening the contacts in a minimum of time.

Abstract: A circuit interrupter characterized by an insulating housing containing a circuit interrupter mechanism, calibration means operatively connected to the mechanism for adjusting operation of the contacts, the housing having a hole aligned with the calibration means, and a plastic plug in the hole, whereby a tamper-proof circuit interrupter is provided.
