Fusible Link1846850
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, thus allowing 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 selection of styles and various temperature ratings.
An electrical fusible link is a kind of electrical fuse that is constructed simply with a brief piece of wire usually 4 American wire gauge sizes smaller sized than the wire that is being protected. For instance, an AWG 16 fusible link may be used to protect 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.
