Fusible Link704749
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 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 higher-security safes also utilize fusible link-primarily based relockers as a defense against torches and heat-creating tools. Mechanical fusible links come in a selection of styles 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 4 American wire gauge sizes smaller than the wire that is becoming protected. For example, an AWG 16 fusible link may be utilized to shield AWG 12 wiring. Electrical fusible links are typical in higher-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.
