A fused tap for an elbow connector that properly insulates and houses an interruption device or fuse to provide protection on underground distribution power lines. The interruption device is replaceable without the need of replacing the entire assembly. The fused tap provides flexibility in installation for existing and new underground distribution lines and/or feeders.

Fuse assemblies, systems and methods of manufacture include reinforcement materials and arc absorbent materials to provide overcurrent protection for 1500 VDC power systems without enlarging the body of the fuse.

A photovoltaic in line connector assembly has an integral fuse, and is double molded to provide electrical insulation, protection and strain relief. The assembly can be integrated with, or added to, a wiring harness for a photovoltaic installation, thereby providing one fuse per solar panel. The assembly may include zero, one, or two connectors that are male, female, or one of each.

A current-limiting fuse for an electronic apparatus, such as, for example, a transformer. The fuse can be withdrawable under a liquid insulating medium, such as oil, and is capable of being replaceable in the field. The fuse can include a fuse element that is encased within an electrically insulative sheath. Additionally, a plurality of contact blades can extend from a lower portion of the fuse and be securely engaged with contact clips that are in electrical communication with one or more components of the electronic apparatus. The contact blades can be positioned within a dielectric insulating medium while a reminder of the fuse between the contact blades and the enclosure can be positioned within an air gap. Further, the contact blades can accommodate seating of the fuse within the enclosure and/or an associated canister.

An electrical fuse includes a housing, first and second terminal assemblies coupled to the housing, and at least one fuse element assembly extending internally in the housing and coupled between the first and second terminal assemblies. A filler surrounds the at least one fuse element assembly, and the filler includes sodium silicate sand and at least one reinforcing structure suspended within the filler.

A fuse including a fuse body defining an inner cavity and having at least one fuse body aperture formed therethrough, a fuse element including a first terminal and a second terminal, a first endbell and a second endbell coupled to the fuse element, the first endbell having at least two grooves formed in a surface thereof and having a first O-ring seal disposed in at least one of the grooves, the second endbell having at least two grooves formed in a surface thereof and having a second O-ring seal disposed in at least one of the grooves, an adhesive securing the first and second endbells to the fuse body, an arc quenching material disposed within the inner cavity and contacting at least a portion of the fuse element, and end caps coupled to the fuse body, the end caps sealing a portion of the fuse element within the fuse body.

Provided herein are protection devices, such as fuses. In some embodiments, a fuse may include a hollow body having first and second ends, each of the first and second ends having an end surface and a side surface extending from the end surface. The fuse may further include a fusible element disposed within a central cavity of the hollow body, the fusible element extending between the first and second ends. The fuse may further include an inner cap formed over at least one of the first and second ends. The inner cap may include a center portion in contact with the fusible element, and a plurality of spring legs extending from the center portion, wherein the plurality of spring legs is in contact with the side surface of the first and/or second ends. The fuse may further include endcaps surrounding the first and second ends.
