Patent number: 10068735Abstract: A lever assembly is for an operating mechanism of an electrical switching apparatus. The electrical switching apparatus includes a number of pairs of separable contacts structured to move from a CLOSED position to a TRIPPED OPEN position in response to a trip condition. The operating mechanism has an enclosure member and a number of biasing elements coupled to the enclosure member. The biasing elements are structured to move the separable contacts from the CLOSED position to the TRIPPED OPEN position. The lever assembly includes a lever member structured to engage the enclosure member, and a component located on the lever member. The component is structured to extend through each of the biasing elements in order to lengthen each of the biasing elements when the separable contacts are in the CLOSED position.Type: GrantFiled: April 15, 2016Date of Patent: September 4, 2018Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Frank Joseph Stifter, Jr., David Curtis Turner, William George Eberts, Kenneth Martin Fischer, Edward Anthony Prince

Patent number: 10020154Abstract: An operating mechanism including a number of biasing elements and a number of linkage members is provided. The linkage members are operatively coupled to each other and each are movable between a second configuration, an initial tripped configuration, a rebound configuration, and a final tripped configuration. The biasing elements are operatively coupled to the number of linkage members and bias the number of linkage members to the final, first configuration. A stop member is coupled to one of the linkage members. The stop member moves with the associated linkage member. The stop member is positioned to contact a stop surface when the linkage members are in the rebound configuration. Contact between the stop member and the stop surface substantially arrests the motion of the linkage members.Type: GrantFiled: September 8, 2016Date of Patent: July 10, 2018Assignee: EATON INTELLIGENT POWER LIMITEDInventors: Raymond Lee Jurek, David Curtis Turner, Jack Edward Devine, Bradley Patrick Rizzo, Brian Scott Jansto

Patent number: 9842715Abstract: Electrical switching apparatus and strain relief assemblies therefor are described herein. In one exemplary, non-limiting embodiment, a strain relief assembly includes a cover and a base, each of which include a number of grooves structured to receive a number of wires. Each groove has a first side and a second side, where the second side is located opposite the first side. Furthermore, located on the first side and/or the second side are a number of protrusions. The grooves and the protrusions serve to secure the number of wires within the strain relief assembly such that, if a force is applied to an end of the wire, the protrusions work to retain the wires with the assembly.Type: GrantFiled: December 4, 2015Date of Patent: December 12, 2017Assignee: EATON CORPORATIONInventors: Jack Edward Devine, David Curtis Turner, Stephanie Feejin Lee, Bradley Patrick Rizzo, Mark Anthony Janusek, Richard Paul Malingowski, James Patrick Sisley
