What Is a Fusible Link?
A fusible link is a type of overcurrent protection device used in electrical circuits and electronic devices.
Typically, it consists of a thin wire or strip made of conductive material, designed to break when the current exceeds a predetermined threshold. By breaking the circuit, it interrupts the flow of current, thereby protecting the circuit or device from overcurrent.
Fusible links are used in various applications such as electronic devices, electrical wiring, and automotive electrical systems, serving to prevent damage to equipment due to overcurrent and the risk of fire from component overheating. When selecting a fusible link, factors such as current capacity, tripping characteristics, and size are taken into consideration.
