Patent number: 11984282Abstract: A circuit breaker, in particular of a power breaker, having a busbar which is mounted so as to be movable between a closed position and an open position. The busbar, a trip device and a hand lever are coupled by means of the mechanism in such a way that, when the hand lever is moved from the first position into the second position, the busbar is moved from the open position into the closed position. Upon tripping of the trip device, the busbar is moved from the closed position into the open position, and the hand lever is moved from the second position into the first position if it is not blocked. When the hand lever is moved from the second position into the first position, the busbar is moved from the closed position into the open position regardless of whether the busbar is blocked in the closed position.Type: GrantFiled: January 3, 2022Date of Patent: May 14, 2024Assignee: Ellenberger & Poensgen GmbHInventors: Hubert Harrer, Hendrik-Christian Koepf, Klaus Loos, Klaus Werner, Juergen Zeberl
