The invention provides a fuse that has a simple structure without having a flap included in a conventional fuse but can prevent a terminal of a different fuse from entering from an opening of an insulating housing. A fuse includes a pair of conductive terminals (10), a fuse element (30) including a fusing part (20) provided between the conductive terminals (10), and an insulating housing (40) covering the fusing part (20) and at least part of the conductive terminals (10) and having an open bottom end. The insulating housing (40) has an open end (50) provided, on an inner wall surface thereof, with a projection (60).

A self-powered wireless fuse switch is disclosed that is a plug-in replacement for a fuse found in the electrical system of vehicles. The self-powered wireless fuse adds remote-controlled switching capabilities for short and long-range control of power to subsystems of a vehicle electrical system. The wireless fuse switch includes a wireless control module having an internal power supply and an internal transceiver that receives commands from a remote control unit. A separate fuse module includes an outer housing and fuse blades that extend from the outer housing and interface with a fuse socket of the vehicle to selectively allow or interrupt power from the vehicle to the subsystem of the vehicle electrical system. The fuse module includes a fusible link, a relay controller and a relay in the outer housing. The fuse module receives power from and communicates with the wireless control module.

Provided is a current fuse that can improve the rating while also preventing explosive scattering of metal in association with arc discharge and enabling reliable cutting off of a circuit. The current fuse (1) includes an insulating substrate (2), a main fuse element (3) disposed on the insulating substrate (2), and a sub-fuse element (4) disposed on the insulating substrate (2) and having a higher melting point than the main fuse element (3). The main fuse element (3) and the sub-fuse element (4) are connected in parallel.

Method of manufacturing a high voltage power fuse having a dramatically reduced size facilitated by silicated filler material, a formed fuse element geometry, arc barrier materials and single piece terminal fabrications. The method includes: connecting a full-range fuse element assembly including first and second metal strip fuse elements defining a plurality of weak spots therein and being connected in parallel to one another, the first metal strip fuse element configured to uniquely respond to a short circuit current condition and the second metal strip fuse element configured to uniquely respond to an overload current condition and a set of arc barriers at selected locations to surround respective cross sectional portions are disclosed.

The invention relates to a safety device (1), comprising: a fusible member (2) having a first segment (3), a second segment (4), and a connecting segment (5), which connects the first segment (3) to the second segment (4). The safety device (1) further comprises a separation element (6), configured to suppress a light arc between the first segment (3) and the second segment (4). The first segment (3) of the fusible member (2) extends along a first side of the separation element (6), the second segment (4) of the fusible member (2) extends along a second side of the separation element (6) located opposite the first side, and the connecting segment (5) of the fusible member (2) extends along a third side of the separation element. It is thus achieved that a light arc between the first segment (3) and the second segment (4) of the fusible member (2) cannot exist even if the spatial distance between the first and the second segment (3, 4) of the fusible member (2) is so minimal that it allows a skipping of a light arc.

In one embodiment, a method of manufacturing a high voltage power fuse includes inserting a housing over a first assembly leg of an assembly frame, assembling a first terminal fabrication to the first assembly leg of the assembly frame, assembling a second terminal fabrication to a second assembly leg of the assembly frame, connecting a full-range fuse element assembly in a gap between the first terminal fabrication and the second terminal fabrication, sliding the housing over the connected full-range fuse element assembly, securing the housing in position to enclose the full-range fuse element assembly, and applying a silicated filler material to the assembled housing, full-range fuse element, and first and second terminals to establish a mechanical bond between the silicated filler material and the assembled housing, full-range fuse element, and first and second terminals.

An embodiment of a fuse module has been disclosed. The fuse module includes a housing, a fuse element unit disposed within the housing, and a pair of terminal blades between which the fuse element unit is electrically connected. Each terminal blade has a pair of connection portions.

A touch-safe fuse module includes a built-in slidable handle movable between extended and retracted positions relating to a housing of the fuse module. In the extended position, the handle assists with removal of the fuse from a base housing assembly by improving mechanical leverage to apply extraction force to the housing. Fuse modules having high current ratings may be effectively removed by hand without separately provided tools.
