Fuses and Fuse Links are essential protective devices used to safeguard electrical circuits from overcurrent and short circuits. A fuse contains a metal element that melts when current exceeds safe levels, interrupting the circuit. Fuse links are the replaceable elements inside fuses, ensuring cost-effective and easy maintenance. Widely used in power distribution, industrial equipment, automotive, and household systems, they provide reliable protection, compact design, and quick fault response.
Description
Fuses and Fuse Links are critical electrical protection devices designed to prevent damage caused by overloads and short circuits. A fuse interrupts excessive current flow by melting its internal element, while a fuse link is the replaceable melting element housed inside the fuse body. Together, they ensure safety, reliability, and cost-effective maintenance in electrical and electronic systems.
