Fusible Link1543782
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 developed to melt at a particular temperature, thus permitting 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-creating tools. Mechanical fusible hyperlinks come in a selection of designs and different temperature ratings.
An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire usually 4 American wire gauge sizes smaller sized than the wire that is being protected. For instance, an AWG 16 fusible link might be used to shield AWG 12 wiring. Electrical fusible hyperlinks are common in higher-present automotive applications. The wire in an electrical fusible link is encased in high-temperature fire-resistant insulation to reduce hazards when the wire melts.
