An electrical device assembly and method to attach an isolated single stud fuse assembly to an electrical device are disclosed. The electrical device assembly consists of multiple studs, one or more of which is replaced with the isolated single stud fuse. A conductive copper landing zone receives an electrically isolated steel stud. When the landing pad assembly is orbital riveted into a plastic housing of the electrical device, the stud is locked into the housing permanently. Electrical devices such as disconnect switches and power distribution modules, both of which include multiple studs, are good candidates for being adapted with the single stud fuse assembly.

A protective device to be integrated into a high-voltage cable of a high-voltage on-board power supply includes a cut-out for interrupting at least one electrical conductor of the high-voltage cable in a fault scenario, a shielding element for forming a cable shield with a shielding conductor of the high-voltage cable, and a housing to be arranged between two high-voltage-cable sections of the high-voltage cable. In the housing, the cut-out and the shielding element are arranged, and the housing has contacts for connecting the cut-out to conductor sections of the at least one conductor and for connecting the shielding element to shielding-conductor sections of the shielding conductor. At least a part of the housing is capable of being non-destructively detached from the high-voltage-cable sections, in order to enable an exchange of at least the cut-out in the case of a defect of the cut-out.

Disclosed are a fuse, a fuse box, and a fuse device capable of preventing insertion of wrong products into the box or device and persistent electric arc. In certain aspects, the fuse includes a pair of electro-conductive terminals, a fuse element having a fusion portion provided between the electro-conductive terminals, and an insulating housing mounted so as to cover at least a part of the fusion portion and the electro-conductive terminals, wherein a notch is provided on a lower-end side of the insulating housing, the notch is located between the pair of electro-conductive terminals and at a position that does not interfere with the shape of the fusion portion provided between the pair of electro-conductive terminals, and the notch is formed in a manner that a protrusion provided in a fuse box for housing the fuse can be fitted therein.

Disclosed herein are efficient mechanical fuse devices that are capable of functioning at high current levels. These devices comprise mechanical features configured such that the fuse devices have a non-triggered state, which allows current to flow through the device, and a triggered state, which does not allow current to flow through the device. In some embodiments, the devices are configured such that a certain pre-determined current level flowing through the device will generate a sufficient electromagnetic field to cause the mechanical elements to transition the fuse device into the triggered state and thus interrupt a connected electrical circuit, device or system. In some embodiments, these devices can also comprise hermetically sealed components. In some embodiments, the fuse devices can comprise pyrotechnic features.
