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 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 make use of fusible link-based relockers as a defense against torches and heat-creating tools. Mechanical fusible links come in a selection of designs and various temperature ratings.An electrical fusible link is a type of electrical fuse that is constructed simply with a short 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 used to protect AWG 12 wiring. Electrical fusible hyperlinks are typical in high-current automotive applications. The wire in an electrical fusible link is encased in higher-temperature fire-resistant insulation to reduce hazards when the wire melts.View much more video clips regarding elsie fusible links.
