Publication number: 20060071741Abstract: A circuit breaker including a housing, separable contacts, a cradle rotatably mounted within the housing, an alarm switch mounted within the housing, and an interface lever disposed between the cradle and the alarm switch. The cradle is adapted to rotate about a first axis in a first direction when the circuit breaker moves to a tripped position in which the separable contacts are separated from one another. The alarm switch includes an actuation lever movable in an actuation direction, wherein movement of the actuation lever in the actuation direction causes the alarm switch to activate an alarm device electrically connected thereto. When the cradle rotates in the first direction, the cradle exerts a first force against the interface lever that causes the interface lever to exert a second force against the actuation lever that causes the actuation lever to move in the actuation direction.Type: ApplicationFiled: September 14, 2005Publication date: April 6, 2006Inventors: Erik Bogdon, Joseph Humbert, Douglas Marks, Craig Rodgers, Dominic Martelli

Patent number: 6812423Abstract: A circuit breaker includes separable contacts, a trip mechanism having an armature mechanism responsive to selected conditions of current flowing through the contacts, and an operating mechanism for opening and closing the contacts. The operating mechanism includes an open position, a closed position, a tripped open position, a lock, a first link and a second link having a base and a pair of legs. The lock is pivotally mounted to and substantially between the legs of the second link. The first link is pivotally mounted to the second link. The first link and the second link have an unbroken state in the closed position and a broken state in the tripped open position. The lock maintains the unbroken state in the closed position and responds to the armature mechanism to release the first link and the second link to the broken state in the tripped open position.Type: GrantFiled: October 24, 2003Date of Patent: November 2, 2004Assignee: Eaton CorporationInventors: Craig A. Rodgers, Lance Gula, Robert M. Slepian

Patent number: 6700082Abstract: A plunger mechanism provides for automatic tripping of a circuit breaker upon the opening of a cover of electrical equipment connected adjacent to the circuit breaker. One end of the plunger mechanism protrudes from the circuit breaker's housing adjacent to the cover, and the other end of the plunger mechanism engages the latch within the trip mechanism of the circuit breaker. Upon opening the cover, the plunger is depressed by the cover, rotating the latch, thereby tripping the circuit breaker.Type: GrantFiled: December 20, 2002Date of Patent: March 2, 2004Assignee: Eaton CorporationInventors: Jeffrey S.

Publication number: 20040032702Abstract: An adapter mechanism is configured to permit a previously known accessory device that had been configured to be used in conjunction with a previously known circuit breaker to be operatively connected with a different type of circuit breaker. The adapter mechanism includes a first interface that is engageable with a handle of the circuit breaker as well as a second interface that is engageable with a movable arm or a latch mechanism of the circuit breaker. The adapter mechanism further includes a support member upon which the first interface is rotatably disposed, with the support member being formed with a plurality of clips that permit the support member and thus the adapter mechanism to be removably mounted on the circuit breaker.Type: ApplicationFiled: August 16, 2002Publication date: February 19, 2004Inventors: Jeffery Gibson, Craig A.

Publication number: 20040000469Abstract: A circuit breaker includes a handle having OFF, ON and intermediate positions, and an extension. A blocking disk has a spring, and first, second and third surfaces. The handle and disk are co-pivotally mounted. The extension engages the third surface for rotation therewith. A pivot lever includes a first end adapted for engagement with a movable contact arm, and a second end adapted for engagement with the first and second surfaces. The first surface blocks the second end as the handle moves from OFF toward the intermediate position, and releases the second end to the second surface at the intermediate position. The first end blocks movement of the movable contact arm when the first surface blocks the second end, and releases the movable contact arm when the first surface releases the second end, thereby moving a movable contact toward a fixed contact in response to the bias of a spring.Type: ApplicationFiled: June 27, 2002Publication date: January 1, 2004Inventors: Jeffrey S.
