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.
Claims19
A motor drive comprising:
- a device for safe fitting of the motor drive with a circuit breaker, the device including
- at least one first cover, to prevent fitting of the motor drive with the circuit breaker in the event that a handle of the circuit breaker is in an incorrect position;
- and
- at least one receiving opening, to allow a handle of the circuit breaker to be received when the handle is in a correct position and to couple the motor drive to the handle of the circuit breaker, a position of the at least one first cover of the device being alterable in such a way that only the at least one receiving opening provides a free space for receiving the handle owing to an overlap by the at least one first cover, the circuit breaker being only being fittable on the motor drive when the handle is in the correct corresponding position.
