The invention of the present application provides a fuse that is easily attached directly or indirectly to a battery. A fuse fixed to a battery post BP or a coupling post of a base member coupled to the battery post BP includes: a fuse element including an input terminal fixed to the battery post BP or the coupling post, an external output terminal, and a fusion portion provided between the input terminal and the external output terminal; a housing including an exposure window through which the fusion portion is exposed, the housing accommodating the fuse element; and a cover member that covers the exposure window. The cover member includes a protruding portion protruding toward a battery BT side including the battery post BP or a base member side, and the protruding portion is able to abut on a part of the battery BT or a part of the base member.

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.

A high-capacity miniature cartridge fuse is provided. A fuse includes a cylindrical housing, a fusible wire, and first and second deep-drawn ferrules fabricated from aluminum alloy. The aluminum is plated with nickel. The ferrule includes a side wall and an end wall. The side wall surrounds the first or second end of the housing, and has a thickness of approximately 0.50 mm or less. The end wall includes a boss extending toward an interior of the housing, and has a thickness greater than the thickness of the side wall.

A fusible switch disconnect device includes a housing adapted to receive at least one fuse therein, and a switchable contact for connecting the fuse to circuitry. A tripping mechanism and control circuitry are provided to move the switchable contact to an open position in response to a predetermined electrical condition.

The invention refers to a fuse switch module (1) that comprises a casing (2) having an aperture (3) and a cover (4) for closing and opening the aperture (3), and a rotatable fuse cartridge (11) for receiving a fuse (8). The fuse cartridge (11) is rotatable between a switch module closed position in which a fuse (8) is connected with fixed contacts (5,6) to enable current circulation, and a switch module open position in which current circulation through the fixed contacts (5,6) is impeded. The cover (4) and the fuse cartridge (11) are engaged when the cover (4) is closing the aperture (3) and when the fuse cartridge (11) is in the switch closed position, thus, the cover (4) is locked by the fuse cartridge (11) and opening of the cover (4) is impeded while current is circulating through the switch module.

The invention concerns a fuse box, comprising a busbar (6) and at least one fuse (8) connected to the busbar, each fuse including two opposite end portions (8A, 8B) and a central portion (82), at least the central portion of each fuse and a section of the busbar being encapsulated in a plastic coating layer. The central portion (82) includes a part (84) of reduced cross-section. The two end portions (8A, 8B) include two respective electrical connectors (81A, 81B), and at least the two electrical connectors (81A, 81B) of each fuse (8) are not encapsulated in the plastic coating layer, so that a new fuse (12) can be connected between the two electrical connectors (81A, 81B) in replacement of a blown fuse (8).

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. Methods of manufacture are also disclosed.
