ABSTRACT:
In order to provide a bearing for an already prepositioned switching shaft, fitted with coupling levers, of a low-voltage circuit breaker in the region where the switching forces act, a bearing assembly is provided. The bearing assembly includes a bearing body which is mounted on the housing front wall of the switch pole, surrounding the switching shaft in the form of a half shell. The bearing body includes a subregion which projects between two coupling levers, which are at a distance from one another and are connected to a movable switching contact. It thus forms side guide surfaces for the coupling levers. Such a bearing assembly can be arranged in both the end regions of the switching shaft in multipole circuit breakers.
