Fusible Link2600413
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 developed to melt at a specific temperature, thus 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 higher-safety safes also utilize fusible link-primarily 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 kind of electrical fuse that is constructed merely 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 protect AWG 12 wiring. Electrical fusible links are typical in higher-present automotive applications. The wire in an electrical fusible link is encased in high-temperature fire-resistant insulation to decrease hazards when the wire melts.
