Fusible Link6122705
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 designed to melt at a specific temperature, thus permitting 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 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 sized than the wire that is being protected. For example, an AWG 16 fusible link may be used to protect AWG 12 wiring. Electrical fusible links are common in high-present automotive applications. The wire in an electrical fusible link is encased in high-temperature fire-resistant insulation to decrease hazards when the wire melts.
