摘要： 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.

摘要： An electrical switching system of a circuit breaker, with a first busbar extending in a longitudinal direction, which carries a first contact and a second contact spaced apart therefrom in the longitudinal direction, and which has a first power connection, and with a second busbar extending in the longitudinal direction, which carries a first counterpart contact and a second counterpart contact spaced apart therefrom in the longitudinal direction, and which has a second power connection. The second busbar is mounted so as to be movable in a transverse direction perpendicular to the longitudinal direction, wherein the first busbar partially overlaps the second busbar along the longitudinal direction. In the longitudinal direction, the contacts and the counterpart contacts are arranged between the two power connections in the overlap region.

摘要： A circuit breaker housing for holding a switching device unit and a number of connection contacts for a connection line and/or a busbar. The housing has a first housing part and a second housing part. In the joined, assembled state, the housing parts form a front side and a rear side opposite said front side and at least one connection side and end faces located opposite one another. A holding chamber for a connection module having one of the connection contacts is provided on the front side and/or on at least one of the connection sides.
