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.

Exemplary embodiments of the present disclosure of a fuse may include a fuse body having a first portion and a second portion. The first and second portions may be configured to mate together thereby forming an internal cavity. A first inner termination and a second inner termination may be at least partially attachable to the first and second portions of the fuse body at respective first and second ends. A fusible element may be disposed in the cavity of the fuse body and extendable from the first inner termination at the first end of the fuse body to the second inner termination at the second end of the fuse body. The fusible element may be attachable to the first inner termination at a first connection and the second inner termination at a second connection. The first and second connections may be inspectable when the fuse is in an assembled state.

A fuse and a production method therefor. The fuse includes upper and lower insulating layers provided with terminal electrodes, and a fuse element between the upper and lower insulating layers. The fuse further includes a functional layer provided between the fuse element and the insulating layers. The functional layer includes a substrate and an arc extinguishing material uniformly or substantially uniformly distributed in the substrate; the arc extinguishing material includes a sealed cavity; the substrate includes low temperature co-fired ceramic powder, aerosol silicon oxide, silicon oxide, inert resin, phosphoric acid, and phosphate ester polyester; the content of the arc extinguishing material is 1-50 wt %. The fuse overcomes the shortcomings of phenomena such as deformation, bending, and defects occurring to a fuse element caused by the shrinkage mismatch of the fuse element with a buffer layer and an arc extinguishing layer in a sintering process.

A power fuse for protecting an electrical load subject to transient load current cycling events in a direct current electrical power system is provided. The power fuse includes at least one fuse element assembly that includes an elongated planar substrate, a plurality of fusible weak spots, and a conductor. The weak spots are formed on the substrate and are longitudinally spaced from one another on the substrate. The conductor is separately provided from the substrate and the weak spots. The conductor includes a solid elongated strip of metal having no stamped weak spot openings therein and therefore avoiding thermal-mechanical fatigue strain in the conductor when subjected to the transient load current cycling events. The solid elongated strip of metal includes coplanar connector sections that are mounted to respective ones of the weak spots and obliquely extending sections bent out of plane of the connector sections to extend above the substrate.

A thermal fuse may comprise an electrode and a conductor separated by a phase change material. The electrode may be formed from a conductive material that generates hydrogen when exposed to water or hydrogen peroxide. The phase change material may release water or hydrogen peroxide at or above an activation temperature.
