Locking mechanism for the mounting of two electrical appliances and an apparatus containing such a mechanism.

摘要

The device is moved between an inactive position and a position for locking a mounting device (19) in a mounting position. A plate (27), a blade (30) and a rail (33), retain the locking device in the locking position in an irreversible manner. The device (19) has a support arm (20) moving inside a flange (15) and a circuit breaker case between the inactive position and a mounting position of the breaker and a differential block. An independent claim is also included for an electrical apparatus.
