ELECTRICAL DEVICE AND SYSTEM COMPRISING AN ELECTRICAL MACHINE AND AN ELECTRICAL DEVICE

An electrical device includes a housing including a receiving space in which electrical components of the device are arranged, a cover device including a first cover element and a second cover element, and a sensor unit including a magnetic element and a magnetic sensor, which is configured to provide a detection signal when the magnetic element is detected to be absent. The first cover element has a cut-out, and the second cover element is arranged such that the second cover element, in a first position, covers the cut-out and, in a second position, allows access to the cut-out. The cover device is arranged such that the cover device, in a first position, closes the receiving space when the second cover element is in the first position, and in a second position, allows access to the first sub-receiving space and the second sub-receiving space.
