Patent number: 7800007Abstract: A circuit breaker subassembly is disclosed. The subassembly includes a base, an operating mechanism, a one-piece non-conductive rotor disposed within the base, and a plurality of sets of contact arms supported by the rotor. The rotor is disposed in operable connection with the operating mechanism and includes a rotational degree of freedom relative to the base with portions of the rotor disposed between each set of the plurality of sets of contact arms to define separation portions. The operating mechanism includes a frame disposed within the base, a cradle in pivotal connection with the frame, an upper link in pivotal connection with the cradle, and a lower link having a first end and a second end, the first end in pivotal connection with the upper link and the second end in pivotal connection with the rotor at the separation portions.Type: GrantFiled: June 26, 2007Date of Patent: September 21, 2010Assignee: General Electric CompanyInventors: Narayansamy Soundararajan, Girish Hassan Mruthunjaya, Yatin Vilas Newase

Patent number: 7342474Abstract: A circuit breaker configured to be remotely operated is disclosed. The circuit breaker includes a set of main contacts configured to connect between an electrical source and an electrical load, an operating mechanism in operable communication to open and close the main contacts, and a remotely operable drive system configured to open and close the main contacts separate from actuation of the operating mechanism. The drive system includes a motor responsive to first and second control signals, a primary drive responsive to the motor, and an opening spring responsive to the primary drive, the main contacts being responsive to the opening spring. In response to the first control signal, the primary drive moves to charge the opening spring, and in response to the second control signal and the main contacts being closed, the primary drive moves to allow the opening spring to discharge thereby resulting in the main contacts opening independent of the motor.Type: GrantFiled: November 16, 2005Date of Patent: March 11, 2008Assignee: General Electric CompanyInventors: Roger Castonguay, Joseph G. Nagy, Narayansamy Soundararajan, Dennis Zuffelato, Craig Benjamin Williams, Heather Pugliese

Patent number: 7189935Abstract: A contact arm assembly having a contact arm module is disclosed. The contact arm module includes a set of contact arms, two side plates, a pivot pin, and a set of springs. Each contact arm includes a pivot hole, two contacts, and two spring holders. The two side plates are disposed on an opposing side of the set of contact arms, each side plate having a pivot hole, and first and second support anchors. A first spring support is disposed at the first support anchors of each side plate, and a second spring support is disposed at the second support anchors of each side plate. The pivot pin is disposed through the pivot holes of the set of contact arms and the pivot holes of the two side plates. The set of springs are disposed between one of the first and second spring supports and one of the spring holders of the set of contact arms.Type: GrantFiled: December 8, 2005Date of Patent: March 13, 2007Assignee: General Electric CompanyInventors: Girish Hassan, Narayansamy Soundararajan, Yatin Vilas Newase

Patent number: 7019606Abstract: A circuit breaker configured to be remotely operated by a controller is disclosed. The circuit breaker includes a set of main contacts, an operating mechanism, a remotely operable drive system configured to open and close the main contacts separate from actuation of the operating mechanism, and a control circuit in operable communication with the main contacts. The drive system includes a motor, and a primary drive responsive to the motor and in operable communication to open and close the main contacts. The control circuit indicates a closed main contact state in response to the operating mechanism being in an on position and the main contacts being closed, and an open main contact state in response to the operating mechanism being in an on position and the main contacts being held open via the drive system.Type: GrantFiled: March 28, 2005Date of Patent: March 28, 2006Assignee: General Electric CompanyInventors: Craig B. Williams, Henry H. Mason, Jr., Roger Castonguay, Joseph G. Nagy, Heather Pugliese, Narayansamy Soundararajan, John Dougherty
