Fuse is mainly composed of two parts: the melt and the fuse tube or fuse holder on which the melt is installed. 1) Melt Melt is an important part of the fuse, often made into filaments or sheets. There are two kinds of melt materials, one is low melting point materials, such as lead, zinc, tin and tin-lead alloys; The other is high-melting materials, such as silver and copper. 2) Fuse tube The fuse tube is the protective shell of the melt, and has the effect of extinguishing the arc when the melt is fused.
