Fusible Link2184746
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 designed to melt at a particular temperature, therefore 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, and so on. 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 selection of designs and various temperature ratings.
An electrical fusible link is a type of electrical fuse that is constructed simply with a brief piece of wire usually 4 American wire gauge sizes smaller than the wire that is becoming protected. For instance, an AWG 16 fusible link might be used to shield AWG 12 wiring. Electrical fusible links are typical in high-present automotive applications. The wire in an electrical fusible link is encased in higher-temperature fire-resistant insulation to reduce hazards when the wire melts.
