Abstract:
1. A fuse box for an electrical cut-off device, this electrical cut-off device comprising a closed enclosure of the electrical cut-off device containing at least one pair of fixed electrical contacts associated with at least one moving electrical contact coupled with an operating device and a receiving area to receive the fuse box, the fuse box comprising a closed enclosure of the fuse box containing at least one fuse provided with connection areas arranged so as to be connected to the fixed electrical contacts of the electrical cut-off device through connection openings provided respectively in the fuse box and in the electrical cut-off device, the fuse box and the electrical cut-off device having complementary fit-in shapes so as to be assembled together so that the fuse box is a separate element being mountable on the electrical cut-off device and is entirely removable, the fuse box comprising a handle arranged so as to move the fuse box into at least one passive position where it is connected to the electrical cut-off device but not locked and the electrical cut-off device is in an open position, and an active position where the fuse box is connected and locked to the electrical cut-off device, and the electrical cut-off device is able to be switched from the open position to a closed position and vice-versa, wherein the handle is arranged so as to move the fuse box into an intermediate position, located between the passive and the active positions where the fuse box is partly removed from the electrical cut-off device, such position corresponds to a disconnected position of the electrical cut-off device where the electrical cut-off device cannot be closed, wherein the fuse box comprises at least one connection element located inside the enclosure and connected, on one side, to one of the connection areas of the fuse and intended to be connected, on the other side, to one of the fixed contacts of the electrical cut-off device through the connection opening when the fuse box is in the active position, and the enclosure of the fuse box comprises at least one translucent section located in front of the connection element to see the connection element so as to visualize the electrical cut-off between the connection element and the fixed electrical contact of the electrical cut-off device when the fuse box is in its intermediate position.
