Fusible links include mechanical and electrical devices.

A mechanical fusible link is a device consisting of two strips of metal soldered together with a fusible alloy that is developed to melt at a particular temperature, therefore allowing the two pieces to separate. Mechanical fusible links are utilized as the triggering device in fire sprinkler systems and mechanical automatic door release mechanisms that close fire doors in warehouses, and so on. Some high-safety safes also utilize fusible link-primarily based relockers as a defense against torches and heat-creating tools. Mechanical fusible links come in a selection of designs and different temperature ratings.

An electrical fusible link is a type of electrical fuse that is constructed merely with a brief piece of wire usually four American wire gauge sizes smaller sized than the wire that is being protected. For example, an AWG 16 fusible link might be used to protect 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.
