Fusible Link7336737
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 developed to melt at a particular temperature, therefore 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, and so on. Some high-security safes also make use of fusible link-based relockers as a defense against torches and heat-producing tools. Mechanical fusible links come in a variety of designs and various temperature ratings.
An electrical fusible link is a type of electrical fuse that is constructed simply with a brief piece of wire typically 4 American wire gauge sizes smaller sized than the wire that is being 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 decrease hazards when the wire melts.
