Generally, to fuse is to combine two objects via the process of fusion.
Fuses are often characterized as "fast-blow" or "slow-blow," according to the time they take to respond to an overcurrent condition. Fast-blow fuses (sometimes marked 'F') open quickly when the rated current is reached. Ultrafast fuses (marked 'FF') are used to protect semiconductor devices that can tolerate only very short-lived overcurrents. Slow-blow fuses (often marked 'T') can tolerate a transient overcurrent condition, but will open if the overcurrent condition is sustained.
Fuses are often sold in standardised packages to make them easily interchangeable. Cartridge fuses are cylindrical and are made in standard lengths such as 20mm, 1" and 1.25". Low-power fuses have a glass body so that the fuse wire can be inspected. High-power fuses have a stronger ceramic body filled with sand.
Blade fuses, with a plastic body and two prongs that fit into sockets, are used in automobiles.
Old electrical consumer units (also called fuse boxes) were fitted with fuse wire that could be replaced from a supply of spare wire that was wound on a piece of cardboard. Modern consumer units contain magnetic circuit breakers instead of fuses.

Fuse is also a music television network like MTV, formerly called MuchMusic USA until it was sold in early 2003. The format is still very similar to the original MuchMusic in Canada, based in Toronto. Like MTV, Fuse now has studios headquartered on Times Square in New York City.

FUSE is also an Acronym for Field Upgradeable Systems Environment, which is a Reconfigurable Computer operating system (RCOS) provides a consistent and easy to use high level interface to FPGA based Reconfigurable Computing products from, among other Nallatech, see " class="external">http://www.nallatech.com
