Series RT14 fuses with cylindrical caps are applicable in distribution units with rated voltage up of 380V a. c. and rated current up to 100A for overload and short-circuit protection. The series consists of fuse-links with cylindrical caps of high rupturing capacity and fuse holders
The two ends of the fuse-elements are welding connected to the cylindrical caps. Near the hottest part of the fuse-element a proper amount of low melting point alloy is applied making the fuse-link having lower action temperature and power dissipation. Thus the fuse-link may adapt to overload and hardly any aging occurs.
The fuse-holder is the assembly of fuse-base and fuse-carrier. The base is the fixed part of the fuse-holder, which is composed of electric contacts parts coordinated with the fuse-link and connecting terminals. The fuse-carrier is a movable part of the fuse-holder used to load. unload and carry the fuse-link. Two styles of screw fixing and rail mounting of fuse-holder are available.
