The basic composition of the fuse
- Sep 10, 2018 -

General fuse consists of three parts: one is the melt part, it is the core of the fuse, the role of cutting off the fuse, the same type, the same specification fuse melt, the same material, geometrical size to the same, the resistance value as small and consistent, the most important is the fusing characteristics to be consistent, household fuses commonly used lead-antimony alloy made The second is the electrode part, usually has two, it is the melt and the circuit connection important component, it must have the good electrical conductivity, should not have the obvious installation contact resistance; The third is the stent part, the fuse is generally thin and soft, the role of the stent is to fix the melt and make three parts become rigid overall easy to install, use,

It must have good mechanical strength, insulation, heat resistance and flame retardancy, in use should not produce fracture, deformation, combustion and short-circuit phenomena.
