Fuse, including at least one fuse blade, formed in a sheet having two opposite main faces extending along a longitudinal axis of the fuse blade, each fuse blade comprising a portion having a reduced section defining a plane transverse to the fuse blade. The fuse also includes arc guards made of a preformed elastic material and associated in pairs, the arc guards of the same pair being each located opposite one another on a respective main face of the same fuse blade. For at least a first pair of arc guards, a layer of adhesive is interposed between the fuse blade and an internal face of each arc guard of this pair, the internal face being oriented towards one of the main faces of the fuse blade, so as to fix each arc guard on the fuse blade.

A compact fusible disconnect switch device includes a magnetic arc deflection assembly including at least a pair of magnets disposed about a switch contact assembly. The magnetic arc deflection assembly facilitates reliable connection and disconnection of DC voltage circuitry well above 125 VDC with reduced arcing intensity and duration. Multiple pairs of magnets may apply magnetic fields in directions opposing one another to deflect electrical arcs in different directions at more than one location in the switch contact assembly to facilitate high voltage DC operation.

Provided herein are approaches for securing an electrical protection device (e.g., a fuse). In one approach, an apparatus includes a conductor and a terminal coupling the conductor to the fuse, wherein the terminal includes an end cap having a cavity for receiving and securing the conductor, and a set of contact elements extending from a base member. The base member may be coupled to the end cap, and a body of the fuse may be coupled to the base member. In some approaches, a fuse blade of the fuse is disposed between the set of contact elements. In some approaches, the apparatus further includes a cover adjacent the terminal, wherein the cover is configured to engage the contact elements to increase a contact force and electrical connection between the set of contact elements and the fuse blade.

A fuse including a fuse body, a fuse element including a first terminal end extending from a first end of the fuse body, and a second terminal extending from a second end of the fuse body, wherein at least one of the first terminal end and the second terminal end extending out of the respective first and second ends of the fuse body include a strain relief feature, and wherein the strain relief feature is configured to flex in response to thermal fluctuation of the fuse or the surrounding components to which it is attached.

The present invention provides a fuse manufacturing method and a fuse that facilitate an assembling work of the fuse. Disclosed is a method of manufacturing a fuse including a fuse element including a pair of terminal portions and a fusing portion between the terminal portions, a casing for accommodating the fuse element, and a cap for closing openings at both ends of the casing. In this fuse manufacturing method, the fuse element is positioned in the casing such that the terminal portion of the fuse element protrudes from the opening of the casing, and a holding plate for holding the fuse element is inserted between a peripheral portion of the opening of the casing and an abutment piece provided at the terminal portion of the fuse element. Further, in this method, the opening of the casing is closed by the cap so as to cover the holding plate.
