Fusible Link7748721
Fusible links consist of 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, thus 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 high-security safes also utilize fusible link-based relockers as a defense against torches and heat-creating tools. Mechanical fusible hyperlinks come in a variety of designs and different temperature ratings.
An electrical fusible link is a type of electrical fuse that is constructed merely with a brief piece of wire typically four American wire gauge sizes smaller than the wire that is being protected. For example, an AWG 16 fusible link may be utilized to shield AWG 12 wiring. Electrical fusible hyperlinks are typical in high-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.
