The fuse is actually to tighten the fuse system from the moving contacts at the top of both sides of the melt pipe and the moving contacts below, and after pushing the upper ones into the place where the duck's beak protrudes, the phosphor copper sheets made of these are held by Chutian with the moving contacts, and the old and old ones are stuck in the duck's beak. If the short-circuit current passes through the fuse and breaks the fuse, with the help of the upward and downward moving contact spring of the fuse, the fuse will fall quickly, disconnect the circuit, and remove the obstacle line or obstacle device.
