Fusible links consist of mechanical and electrical devices.

A mechanical fusible link is a device consisting of two strips of metal soldered with each other with a fusible alloy that is designed to melt at a specific temperature, therefore permitting the two pieces to separate. Mechanical fusible hyperlinks are utilized as the triggering device in fire sprinkler systems and mechanical automatic door release mechanisms that close fire doors in warehouses, etc. Some higher-safety safes also utilize fusible link-primarily based relockers as a defense against torches and heat-creating tools. Mechanical fusible links come in a variety of designs and various temperature ratings.

An electrical fusible link is a kind of electrical fuse that is constructed merely with a brief piece of wire typically 4 American wire gauge sizes smaller sized than the wire that is being protected. For instance, an AWG 16 fusible link may be utilized to shield AWG 12 wiring. Electrical fusible hyperlinks are common in high-current automotive applications. The wire in an electrical fusible link is encased in higher-temperature fire-resistant insulation to reduce hazards when the wire melts.
