Fusible Link2743642
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 developed to melt at a particular temperature, thus 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, and so on. Some high-safety safes also utilize fusible link-based relockers as a defense against torches and heat-creating tools. Mechanical fusible links come in a selection of styles and different temperature ratings.
An electrical fusible link is a kind of electrical fuse that is constructed merely with a brief piece of wire typically 4 American wire gauge sizes smaller than the wire that is being protected. For instance, an AWG 16 fusible link might 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.
