The present invention provides a fuse that can be easily manufactured and has an improved yield. A fuse includes an input terminal portion, a bus bar portion through which a current input from the input terminal portion flows, and a terminal portion connected to the bus bar portion through a fusible portion, where a fusible portion unit including the fusible portion and the terminal portion is provided in plurals, each of the fusible portion units is a separate body from the bus bar portion and is individually attached to the bus bar portion.

In one embodiment, a fuse assembly comprises a fuse element, an inner chamber comprising arc-quenching liquid, and an outer chamber housing the inner chamber. At least a portion of the fuse element is housed inside the inner chamber. The inner chamber is configured to rupture during an arc event. The outer chamber comprises filler material.

A protective element includes a fuse element, an insulating case, a first terminal, and a second terminal, and also includes an insulating member disposed close to or in contact with the fuse element and having an opening portion or a separation portion formed therein, a shielding member configured to move downward to divide the fuse element, a pressing unit configured to press the shielding member downward, and a locking member configured to restrain downward the shielding member, wherein the shielding member has a convex portion that protrudes toward the fuse element, the convex portion has a tip end disposed at a lower end portion of the convex portion and extends in a width direction, the tip end has a first inclined blade which extends downward as nearing one side in the width direction, and the first inclined blade overlaps a region half the length of the fuse element in the width direction.

A fuse (1) includes a fuse element (10) having a fusible portion (13) provided between opposed inner edges (11a, 12a) of flat plate portions (11, 12), and an insulating housing (50) covering the inner edge sides of the flat plate portions and the fusible portion in a state in which outer edge (11c, 12c) sides of the flat plate portions are protruded outward from slits at respective end walls (55, 58) of the insulating housing (50). The outer edge sides of the flat plate portions are formed as terminal portions (21, 22) each having a thickness twice as large as the thickness of the flat plate portion, and protrusions (11b, 12b) provided on upper and lower edges of the flat plate portions abut against inner surfaces of the end walls (55, 58) of the insulating housing (50).

A fuse cutout assembly cover including an insulator cover end for positioning over a cutout assembly insulator and including a shield end for shielding a cutout upper contact assembly. An intermediate portion between the insulator cover end and the shield end can have detents for retaining the cover in place on the fuse cutout assembly. The fuse cutout cover can include a plurality of hole and slot arrangements to provide multiple access sites for an installation tool such as a shotgun stick or other hot stick tool. Methods of manufacturing fuse cutout assembly covers are also disclosed.

A pressure-compensated fuse assembly may include a first chamber housing a first fluid and a plurality of solid particles. Additionally, the fuse assembly may include a second chamber housing a second fluid. Further, the fuse assembly may include a pressure compensator disposed between the first chamber and the second chamber. The pressure compensator may be configured to transfer pressure from the second fluid in the second chamber to the plurality of solid particles in the first chamber.
