Fusible Link9767852
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, 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-security safes also make use of fusible link-primarily based relockers as a defense against torches and heat-creating tools. Mechanical fusible links come in a variety of designs and various temperature ratings.
An electrical fusible link is a kind of electrical fuse that is constructed merely with a short piece of wire typically four American wire gauge sizes smaller than the wire that is being protected. For example, 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 decrease hazards when the wire melts.
