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 developed to melt at a specific temperature, thus 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 make use of fusible link-primarily based relockers as a defense against torches and heat-producing tools. Mechanical fusible links come in a variety of designs and different temperature ratings.

An electrical fusible link is a kind of electrical fuse that is constructed simply with a brief piece of wire typically four American wire gauge sizes smaller than the wire that is becoming protected. For instance, an AWG 16 fusible link might be utilized to shield AWG 12 wiring. Electrical fusible links are typical in higher-current automotive applications. The wire in an electrical fusible link is encased in higher-temperature fire-resistant insulation to decrease hazards when the wire melts.
