Abstract: A high voltage fuse adapter system and method. A fuse adapter system includes an indicator-end adapter configured to circumferentially enclose an indicator-end terminal of a high voltage IEC rated fuse, including a hollow portion having an inner diameter that surrounds the indicator-end terminal, the hollow portion including at least one axially extending slot compressible around the indicator-end terminal, and an indicator portion, a piston and needle enclosed within the indicator portion, the piston and needle coupled to a striker of the high voltage IEC-rated fuse such that upon extension of the striker, the piston at least partially actuates the needle outside of the indicator-end adapter, a non-indicator-end adapter configured to circumferentially enclose a non-indicator-end terminal of the high voltage fuse, and a pair of end caps enclosing the indicator-end adapter and the non-indicator end adapter to form an adapted fuse configured to fit in an UL-style fuse mounting.

Abstract: A fuse element capable of surface-mounting and capable of increased ratings while maintaining high-speed blowout property; and a fuse device using the same. A fuse element blown by self-generated heat caused when a rate-exceeding current flows therethrough constitutes a current path of a fuse device and has a low melting point metal layer and a high melting point metal layer laminated onto the low melting point metal layer; when the current flows therethrough, the low melting point metal layer erodes the high melting point metal layer and blowout occurs.

Abstract: Fuse assemblies in the form of fuse blocks and fuse holders include embedded permanent magnet arc suppression features that facilitate higher voltage operation of fusible circuit protection without increasing the size of the fuse assemblies. The embedded magnets apply an external magnetic field upon an overcurrent protection fuse and produce an arc deflection force to enhance arc quenching capability of the fuse without increasing its form factor.

Abstract: A compact, high breaking capacity fuse that includes a top insulative layer, at least one intermediate insulative layer, and a bottom insulative layer arranged in a vertically stacked configuration. The at least one intermediate layer may have a hole formed therethrough that defines an air gap within the fuse. A first conductive terminal may be formed on a first end of the fuse and a second conductive terminal may be formed on a second end of the fuse. At least one fusible element may connect the first terminal to the second terminal, thus providing an electrically conductive pathway therebetween. A portion of the at least one fusible element may pass through the air gap defined by the hole in the at least one intermediate insulative layer.

Abstract: A fuse holder, particularly for interlocked sockets and electrical apparatuses in general, includes a tray which is inserted in a seat and is adapted to accommodate a fuse. The tray is movable along a rectilinear path, having at least two positions: an active position, in which the fuse is active, and an extracted position, in which the fuse can be removed from the tray. The seat includes two elastic contact members which provide an electrical and mechanical connection of the fuse in the active position.

Abstract: A surface-mount fuse for protecting a circuit, includes a substrate having first and second surfaces, each surface having first, second, third, and forth ends, the substrate also having first, second, third, and fourth sides. The fuse also includes a metal strip evenly attached to the first surface of the substrate with a layer of adhesive material, the layer of adhesive material being disposed between the metal strip and the first surface of the substrate, the metal strip having a first connection region, a second connection region, and a non-linear fuse link therebetween. The fuse further includes first and second wire leads aligned substantially with and along the first and second connection regions, respectively, the first wire lead being conductively connected to the first connection region and horizontally projecting away from the first connection region, the second wire lead being conductively connected to the second connection region and horizontally projecting away from the second connection region, for connecting the fuse to the remainder of the circuit. The layer of adhesive material can include a polymeric material therein. One alternative for the wire leads can include clip leads or other terminal leads. The fuse also includes a protective layer disposed on the fuse link, the protective layer being in contact with and surrounding the upper and side surfaces of the fuse link of the metal strip. A method of making the same is also disclosed herein.
