Patent number: 6985059Abstract: A circuit breaker includes a crank for coupling a rotary arm breaker mechanism to the cradle. The crank has a protrusion which cooperates with a handle yoke to restrict movement of the operating handle when the contacts of the circuit breaker are welded. The crank protrusion is arranged such that it does not interfere with the handle under normal operating conditions.Type: GrantFiled: September 10, 2003Date of Patent: January 10, 2006Assignee: General Electric CompanyInventors: Ananthram Subramanian, Ronald Ciarcia, Narender Macha, Luis Brignoni, Paul Douglas Lafferty

Patent number: 6980071Abstract: A trip system for a circuit breaker having a support frame, a trip unit, a crossbar, and a trip bar, is disclosed. The trip unit is responsive to an electric current for generating a trip force, the crossbar is directly coupled to the trip unit and to the support frame, and the trip bar is directly coupled to the support frame. The electric current at the trip unit generates a trip force that acts upon the trip bar to trip the circuit breaker. The crossbar remains substantially stationary during the tripping action.Type: GrantFiled: September 24, 2003Date of Patent: December 27, 2005Assignee: General Electric CompanyInventors: Navin Kumar, Christian Daehler, Ronald Ciarcia, Narender Macha, Anantharam Subramanian, Luis A.

Patent number: 6952149Abstract: A circuit breaker includes a housing, an operating mechanism, and a cassette. The cassette includes a separable current path having a movable contact arm, two arc receptors each disposed for receiving an electrical arc in response to a short circuit overcurrent condition, and two slot motors each disposed proximate the movable contact arm for magnetically driving the movable contact arm to a blown open position in response to a short circuit overcurrent condition. The slot motors each have two side legs opposing each other and defining a space therebetween for receiving the movable contact arm, each side leg having a magnetic core and an insulative layer and being biased toward the interior of the side walls of the cassette, wherein each side leg is restrained from being magnetically attracted toward the movable contact arm during a short circuit condition.Type: GrantFiled: May 13, 2003Date of Patent: October 4, 2005Assignee: General Electric CompanyInventors: Ronald Ciarcia, Ananthram Subramanian, Macha Narender, Luis Brignoni, Samuel Kim

Patent number: 6933814Abstract: A molded case, cassette type circuit breaker for a multi-pole electrical distribution circuit includes a number of cassettes equal to the number of poles in the multi-pole electrical distribution circuit and a pin disposed through each cassette. The pin is formed from a dielectric material. The pin may be further disposed through a portion of an operating mechanism for aligning the cassettes and the operating mechanism. Each cassette may include a rotor, a pair of electrical contacts, and a contact arm supported in the cassette by the rotor. In this embodiment, the pin may be a cross pin that extends between each rotor. The dielectric material may include phenolic, melamine, silicone, epoxy, polyester, fiberglass and the like. Alternatively, the pin includes a steel bar coated with the dielectric material, where the dielectric material may include, for example, epoxy, silicon, Teflon, and the like. A pair of end caps may be disposed over end surfaces of the rotor.Type: GrantFiled: May 13, 2003Date of Patent: August 23, 2005Assignee: General Electric CompanyInventors: Ronald Ciarcia, Luis Brignoni, Narender Macha, Anantharam Subramanian, Samuel Stephen Kim
