Fusible Link6194917
Fusible links include mechanical and electrical devices.
A mechanical fusible link is a device consisting of two strips of metal soldered together with a fusible alloy that is designed to melt at a specific temperature, therefore 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 higher-security safes also utilize fusible link-based relockers as a defense against torches and heat-producing tools. Mechanical fusible hyperlinks come in a selection of styles and different temperature ratings.
An electrical fusible link is a kind 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 being protected. For instance, an AWG 16 fusible link might be utilized to shield 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 reduce hazards when the wire melts.
