Abstract

A motor drive includes a device for safe fitting of the motor drive with a circuit breaker. In at least one embodiment, the device includes a first cover, whose position can be altered, for example by being guided in slotted links, in such a way that only the receiving opening provides a free space for receiving the handle, owing to the overlap by the first cover, and therefore it is only possible for the circuit breaker to be fitted on the motor drive when the handle is in the corresponding position.
