Fusible Link5421924
Fusible links include 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, 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, and so on. Some high-safety safes also make use of fusible link-based relockers as a defense against torches and heat-producing 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 simply with a short piece of wire usually 4 American wire gauge sizes smaller than the wire that is being protected. For instance, an AWG 16 fusible link might be utilized to shield AWG 12 wiring. Electrical fusible links are common in higher-current automotive applications. The wire in an electrical fusible link is encased in high-temperature fire-resistant insulation to reduce hazards when the wire melts.
