Patent number: 11342729Abstract: A power panel of an electrical distribution system including a bus stack with a plurality of conductive bars spaced from one another and a plurality of insulators, an electrical accessory is coupled to the plurality of bus bars, and each insulator includes a main body and a safety feature that extends from the main body. The safety features from adjacent insulators extend towards one another to define a gap sized to prevent insertion of a foreign object therein. The gap is further sized to permit insertion there through of a conductive component to establish an electrical connection between multiple bus bars and the electrical accessory.Type: GrantFiled: September 14, 2020Date of Patent: May 24, 2022Assignee: ABB SCHWEIZ AGInventors: Shawn Couceiro Fonseca, Justin Daniel Dubrosky, Dennis James Rehmer

Patent number: 10366853Abstract: A collapsible link device includes a side frame, a carrier, a main contact arm, a plurality of collapsible links, and a release mechanism. The carrier is pivotably coupled to the side frame. The main contact arm is pivotably coupled to the carrier and includes a first end including a first electrical contact. The plurality of collapsible links are pivotably coupled to the side frame and the carrier. The release mechanism is pivotably coupled to at least one of the collapsible links and the carrier. The plurality of collapsible links are movable between an uncollapsed position in which the first electrical contact contacts a second electrical contact and a collapsed position that results from the first electrical contact separating from the second electrical contact.Type: GrantFiled: January 5, 2018Date of Patent: July 30, 2019Assignee: ABB SCHWEIZ AGInventors: Andrew Matthew Candelora, Amit Bose, Dhirendra Kumar Tiwari, Katherine Marjorie Coughlin, Shawn Couceiro Fonseca

Patent number: 9576761Abstract: A circuit breaker crossbar assembly includes a crossbar having a first and second segment, the first and second segment each operatively coupled to a respective moveable contact arm assembly. Also included is a coupling segment disposed between the first and second segment, the crossbar and the coupling segment rotatable about an axis. Further included is at least one support assembly operatively coupled to the coupling segment. The support assembly includes a bushing coupled to the coupling segment and rotatable with the crossbar and the coupling segment. The support assembly also includes a support bracket configured for affixation to a stationary structure and disposed adjacent to the bushing, the bushing rotatable relative to the support bracket. The support assembly further includes a fixing bracket engaged with the support bracket and disposed adjacent to the bushing, the bushing rotatable relative to the fixing bracket.Type: GrantFiled: May 20, 2015Date of Patent: February 21, 2017Assignee: GENERAL ELECTRIC COMPANYInventors: Christie Marie Barbera, Shawn Couceiro Fonseca, Linda Yvonne Jacobs, Dhirendra Kumar Tiwari, Nagesh Venkata Tumu
