Fusible Link7049415
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 particular 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 higher-security 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 styles and different temperature ratings.
An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire usually four American wire gauge sizes smaller sized than the wire that is being protected. For instance, an AWG 16 fusible link may be utilized to protect AWG 12 wiring. Electrical fusible hyperlinks are common in high-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.
