Publication number: 20020030570Abstract: An operating mechanism controls and trips a separable contact structure arranged in a protected circuit. The mechanism includes a frame, a drive member pivotally coupled to the frame, a spring pivotally connecting the drive member to a drive connector, an upper link pivotally seated on the drive connector, a lower link member pivotally coupled to the drive connector, a crank member pivotally coupled to the lower link member for interfacing the separable contact structure, and a cradle member pivotally secured to the frame and pivotally securing the upper link. The cradle member is configured for being releasably engaged by a latch assembly, which is displaced upon occurrence of a predetermined condition in the circuit such as a trip condition. The mechanism is movable between a tripped position, a reset position, an off position, and an on position. Spacers are operatively positioned between movable members, and protrusions are operatively formed on the enclosure of the contact structure.Type: ApplicationFiled: September 20, 2001Publication date: March 14, 2002Inventors: Roger N.

Patent number: 6340925Abstract: A circuit breaker operating mechanism for separating a pair of electrical contacts within an electrical circuit breaker includes a lower link operatively connected to one of the electrical contacts. An upper link includes first and second legs extending from a central portion. The first leg is pivotally secured to the lower link, and the second leg includes a cam surface formed thereon. A roller is in intimate contact with the cam surface, and the cam surface is configured such that movement of the upper link relative to the roller causes the upper link to pivot about the central portion. Pivoting of the upper link about the central portion moves the lower link causing the second contact to move away from the first contact. A mechanism spring is configured to provide a force for separating the electrical contacts when the operating mechanism is tripped. A toggle handle includes a void disposed therein, and an end of the spring is secured to the operating handle within the void.Type: GrantFiled: July 14, 2000Date of Patent: January 22, 2002Assignee: General Electric CompanyInventors: Roger N.

Patent number: 6211757Abstract: A trip actuator (66) includes a trip spring (106) to bias the trip arm (104) in a clockwise direction about trip arm pivot (120). In the latched and ready to operate state, the clockwise moment about the axis of the latch pivot (132) created by force “F” opposes the counterclockwise moment created about the axis of the latch pivot (132) created by the horizontal component “fx” of force “f”, to hold the latch (110) in the upright position against the force of the trip arm (104). When a trip (triggering) signal is provided to the flux shifter (102), the flux shifter (102) releases the plunger (130). With the force “F” removed, the trip arm (104) will drive the latch pin (134), causing the latch (110) to rotate counterclockwise about the latch pivot (132). As the latch (110) and trip arm (104) rotate, the latch pin (134) slides off the latch surface (126), fully releasing the trip arm (104) and allowing the trip paddle (96) to move the secondary latch tab (50).Type: GrantFiled: March 6, 2000Date of Patent: April 3, 2001Assignee: General Electric CompanyInventors: Roger N. Castonguay, James L. Rosen, Dave Christensen, Girish Hassan

Patent number: 6172584Abstract: Compliant assembly (110) includes a reset drive (112) mechanically cooperating with a plunger link (120) having a slide interface latch (130) via an intermediate plunger reset spring (142), plunger link (120) also being proximate to plunger (84) to both accept strikage from or become in mechanical cooperation with plunger (84) and to reset plunger (84) from the protruded position to the retracted position. Further, in the detailed embodiment, reset drive (112) also mechanically cooperates with slide link (132) via an intermediate slide reset spring (60), slide link (132) also being proximate slide (86) to reset slide (86) from the unlatched or released position (after, for example, a trip event causes plunger (84) to protrude into contact with plunger link (120) thereby releasing slide interface latch (130) from slide latch seat (90) of slide (86)) to the latched or set position.Type: GrantFiled: December 20, 1999Date of Patent: January 9, 2001Assignee: General Electric CompanyInventors: Roger N.
