Fusible Link9083380
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 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, etc. Some higher-safety safes also make use of fusible link-based relockers as a defense against torches and heat-creating tools. Mechanical fusible hyperlinks come in a variety of styles and various temperature ratings.
An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire typically 4 American wire gauge sizes smaller 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 higher-temperature fire-resistant insulation to decrease hazards when the wire melts.
