An electrical device, comprising:

• a housing including a receiving space in which electrical components of the electrical device are arranged, the receiving space having a first sub-receiving space and a second sub-receiving space;
• a cover device comprising a first cover element having a cut-out therein, and a second cover element, wherein the second cover element is arranged with respect to the first cover element in such a way that the second cover element, in a first position, covers the cut-out and, in a second position, allows access to the cut-out, wherein the cover device is arranged with respect to the housing in such a way that the cover device, in a first position, closes the receiving space when the second cover element is in the first position, and allows access to the first sub-receiving space of the receiving space through the cut-out and closes the second sub-receiving space of the receiving space when the second cover element is in the second position, and that the cover device, in a second position, allows access to the first sub-receiving space and the second sub-receiving space;
• and
• a sensor unit comprising a magnetic element and a magnetic sensor, which is configured to provide a detection signal when the magnetic element is detected to be absent, wherein the sensor unit is arranged and designed to detect an absence of the magnetic element in the second position of the second cover element and in the second position of the cover device,
• wherein a fuse is arranged in the first sub-receiving space.
