Abstract:

A latch kit comprising a member with at least one hook end, a tension member, and a hook plate. The hook plate is connected to the member by a tension member. The kit is intended to be used in conjunction with an industrial circuit breaker which is secured in a cell by a catch plate.

US Classification:

218154, 218120, 218140

Abstract:

The present invention provides improved and more efficient methods and apparatus for maintaining and/or adjusting over-travel gaps and contact wipe portions in operating rod assemblies of circuit interrupters. According to one embodiment of the invention, a circuit interrupter comprises a fixed electrical contact; a moveable electrical contact; an operating rod assembly comprising at least one contact spring for imparting a corresponding opening or closing force to the contacts; a moveable contact stem operatively coupled between the moveable electrical contact and the operating rod assembly for positioning the moveable electrical contact into or out of engagement with the fixed electrical contact; and an adjustment member adjustably disposed on an opposite end of the circuit interrupter relative to the moveable electrical contact from the at least one contact spring; wherein motion of the operating rod assembly causes the moveable electrical contact to move into or out of engagement with the fixed electrical contact via motion of the moveable contact stem and wherein the moveable electrical contact moves into or out of engagement with the fixed electrical contact with application of force imparted by the contact spring, and wherein the adjustment member is capable of adjusting the force imparted by the contact spring when moving the moveable electrical contact into or out of engagement with the fixed electrical contact.

International Classification:

H02B 11/00

US Classification:

200 5023, 361606, 361609

Abstract:

An interlock assembly for a circuit breaker housing assembly and a circuit breaker extraction device wherein the interlock assembly has a first and second component. The first component is coupled to a circuit breaker housing assembly and the second component is coupled to a circuit breaker extraction device. The first component includes a rail obstruction assembly that is structured to move between a first position, wherein the movable rail obstruction element blocks a circuit breaker wheel from traveling over a circuit breaker housing assembly rail, and a second position, wherein the movable rail obstruction element is spaced from the circuit breaker housing assembly rail so that a wheel may travel over the circuit breaker housing assembly rail. The second component is structured to engage the first component when the circuit breaker extraction device is brought adjacent to the circuit breaker housing assembly and to move the movable rail obstruction element from the first position to the second position.

International Classification:

H01H 3/38

US Classification:

218154, 218140

Abstract:

A mechanism assembly is for a vacuum circuit interrupter including a vacuum housing including a stationary contact and a moveable contact, and an operating mechanism including a drive rod. The mechanism assembly cooperates with the drive rod to open and close the contacts. The mechanism assembly includes a housing having a pair of first longitudinal openings and a pair of second longitudinal openings, the first longitudinal openings defining a first plane, the second longitudinal openings defining a different second plane. A first trunnion member is pivotally and translationally mounted with respect to the first longitudinal openings. The first trunnion member is coupled to the moveable contact. A second trunnion member is pivotally and translationally mounted with respect to the second longitudinal openings. The drive rod is pivotally connected to the second trunnion member.

International Classification:

H01H 523

US Classification:

200401

Abstract:

A molded case circuit breaker having current limiting capabilities is dimensionally optimized for relatively smaller frame size circuit breakers. The handle yoke is supported with rollers thereby allowing the crossbar to be disposed in the space normally utilized for the handle yoke pivot axis. A clinch joint arcer assembly with a plurality of arcing contact arms, each pivotally connected by a clinch joint to a pivotally mounted main contact arm permits additional main contact arms to be provided in the same space normally occupied by the arcing contact arms alone. Additionally, arcing contact spring housings protect the arcing contact springs from deterioration due to corrosive ionizing gases generated during interruption. A positive off link assembly prevents the operating handle from being placed on an OFF position when the main contacts are welded together and transfers the force applied to the operating handle to the upper link to allow the weld to be broken. Lastly, a reversible barrier in one of the sidewalls allows in one position circuit breaker auxiliaries, located in the outside pole compartments, to communicate with the operating mechanism and the operating handle.

International Classification:

H01H 902

US Classification:

335202

Abstract:

A compact power circuit breaker has a molded insulative casing providing the structural support and electrical isolation for the pole mechanisms mounted in cavities in the casing and the operating mechanism mounted to the front of the casing. A grounded barrier between the pole mechanisms and the operating mechanism protects the operator actuating push buttons controlling the operating mechanism and accessible through a molded insulative cover. Preferably, the grounded barrier is sandwiched between a rear section of the molded casing containing the pole cavities and a forward section to which the operating mechanism is secured. The grounded barrier is connected to an electrically conductive pan extending under the molded insulative casing which also houses electrically grounded linkages coupling the operating mechanism to the vacuum interrupters of the pole mechanisms. A vented air gap between the rear section of the molded insulative casing and the grounded barrier minimizes erosion of the molded insulative casing in the event of an arc penetrating the casings to the grounded barrier.
