Fusible Link3470076
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, 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, etc. Some high-safety safes also utilize fusible link-primarily based relockers as a defense against torches and heat-producing tools. Mechanical fusible links come in a variety of designs and different 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 than the wire that is becoming protected. For example, an AWG 16 fusible link might be utilized to shield AWG 12 wiring. Electrical fusible hyperlinks are common in high-current automotive applications. The wire in an electrical fusible link is encased in high-temperature fire-resistant insulation to reduce hazards when the wire melts.
