Electrical fusible link

An electrical fusible link is a type of electrical fuse that is constructed simply with a short piece of wire typically four American wire gauge (AWG) sizes smaller than the wire that is being protected. For example, an AWG 16 fusible link might be used to protect 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.^[2][3]
