Abstract (en)

A DC circuit breaker is provided. The DC circuit breaker comprises a first housing and a second housing, wherein the first housing and the second housing jointly define an accommodation space, and a stationary contact assembly and a mechanism assembly are arranged in the accommodation space, the mechanism assembly being able to move between an on position and an off position. The mechanism assembly comprises a center plate and a moving contact assembly. The center plate is rotatably supported, at both sides of the center plate, by the first housing and the second housing respectively. The moving contact assembly is rotatably installed on the center plate by a moving shaft arranged on the center plate. The moving contact assembly is configured to rotate relative to the center plate during a rotation of the center plate relative to the first housing and the second housing. An elastic component of the mechanism assembly is configured to act between the moving contact assembly and the first housing.
