A fuse includes an integrated measuring function. In an embodiment, the fuse includes a fuse housing which in turn has a first receiving space delimited by a pressure body and a second receiving space which is spatially separated from the first receiving space and is delimited by a protective body, the first and second receiving spaces being arranged one behind the other in a direction of longitudinal extent. A fusible conductor is accommodated and mounted in the first receiving space and a measuring device is accommodated and mounted in the second receiving space. The measuring device has a current transformer and an electronic assembly which is electrically conductively connected to the current transformer. The current transformer and the electronic assembly are arranged one behind the other in the direction of longitudinal extent.

The present disclosure provides a high-temperature thermal pellet composition that maintains structural rigidity up to a transition temperature of about 240° C. The composition comprises at least one organic compound (e.g., triptycene or 1-aminoanthroquinone). The pellet can be disposed in a housing of a thermally-actuated, current cutoff device, such as a high-temperature thermal cutoff device (HTTCO). Also provided are material systems, which include the pellet composition and a high-temperature seal that provides substantial sealing up to at least the transition temperature. Methods of making such high-temperature pellet compositions and incorporating them into a thermally-actuated, current cutoff device are also provided.

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.

A fuse assembly having an end cap that includes a recessed retention body. The recessed retention body can include first and second retention walls and an engagement surface. The first and second retention walls can extend at least in a generally outwardly direction from the retention surface to an outer surface of the end cap, and extend between first and second ends of the first end cap in a direction that is generally parallel to a central longitudinal axis of the fuse assembly. The engagement surface can have one or more walls that downwardly and outwardly extend in divergent directions from an apex of the engagement surface and toward a corresponding one of the first or second retention walls. The apex can be positioned at a central location between the first and second retention walls, and extends in a direction that is generally parallel to the central longitudinal axis.
