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 particular temperature, therefore 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, 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 different temperature ratings.An electrical fusible link is a kind of electrical fuse that is constructed simply with a brief piece of wire typically 4 American wire gauge sizes smaller than the wire that is becoming protected. For instance, an AWG 16 fusible link may be used to shield AWG 12 wiring. Electrical fusible links are common in high-current automotive applications. The wire in an electrical fusible link is encased in high-temperature fire-resistant insulation to reduce hazards when the wire melts.More articles concerning 2TGJ2 now offered for you in one click!
