Fusible Link596115
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 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, etc. Some high-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 kind of electrical fuse that is constructed simply with a brief piece of wire usually four American wire gauge sizes smaller sized than the wire that is becoming protected. For example, an AWG 16 fusible link might be utilized to protect AWG 12 wiring. Electrical fusible hyperlinks are common in higher-current automotive applications. The wire in an electrical fusible link is encased in higher-temperature fire-resistant insulation to decrease hazards when the wire melts.
