Patent number: 9679724Abstract: A contact assembly for an electrical component includes: a bus member; and a switching assembly structured to move between first and second positions. The switching assembly includes: a stationary contact extending from the bus member, a movable contact engaging the stationary contact when the switching assembly is in the first position and disengaging the stationary contact when the switching assembly moves toward the second position, and a switching device coupled to the bus member. When the switching assembly is in the first position, the switching device and the stationary contact are electrically connected in parallel with the bus member and the movable contact. When the switching assembly moves from the first position toward the second position, the switching device disconnects power after the movable contact disengages the stationary contact in order that electrical disconnection between the bus member and the movable contact occurs within the switching device.Type: GrantFiled: July 13, 2015Date of Patent: June 13, 2017Assignee: EATON CORPORATIONInventors: Michael Howard Abrahamsen, Daniel Garett Sims, Matthew Stephen Weidemeier, Robert Kirkland Smith, Hongbin Wang
