Abstract (en)

A moving contact member of circuit breaker, which belongs to the technical field of low-voltage apparatuses, comprises: an insulating support, a pair of fixing plates, a grid plate base, a set of grid plate, a revolving support shaft, a set of parallel conductors, a flexible conductive connecting wire, and a conductive block, wherein, the moving contact member further comprises a fixing support, which is mounted on the insulating support or grid plate base, accompanied with the set of parallel conductor; at least one conductor in the set of parallel conductors is in the fixing support and at a position consistent with the other conductors; the set of grid plates are arranged on either the grid plate base or the insulating support. The advantages of the present invention include: the temperature rise during short circuit on the moving contacts and fixed contacts can be reduced and the performance of short-time current tolerance of the circuit breaker can be improved; the moving contact can be kept small, and the overall volume of the circuit breaker can be controlled effectively; the fixing support is simple in structure and easy to install, which is favorable for economical efficiency and industrial applicability.
