Fuse is a protective device used in electrical systems to prevent overcurrent damage. It features a metal wire or strip that melts when excessive current flows, interrupting the circuit. Common in industrial applications like machinery, power distribution, and control panels, fuses ensure safety by isolating faults. Types include cartridge, blade, and thermal fuses, each suited for specific voltage and current ratings.
