RT14系列圓筒形帽熔斷器適用于額定電壓交流380V，額定電流至100A的配電裝置中作過載保護(hù)和短路保護(hù)。

本系列熔斷器由高分?jǐn)嗄芰A筒形帽熔斷體和熔斷器支持件組成。
熔斷體
熔斷體的熔體兩端焊接在圓筒形端帽上，接近熔體的最熱部位配置適量易熔合金，以使熔斷體有較低的動(dòng)作溫度和耗散功率，使熔斷體能適應(yīng)過載而幾乎不老化。
熔斷器支持件
熔斷器支持件是熔斷器底座和載熔件的組合。底座由插座、接線端子和絕緣座等部件組成;載熔件是用來(lái)裝卸和載運(yùn)熔斷體的熔斷器可動(dòng)絕緣部件。
熔斷器支持件有螺釘固定和電器安裝軌等安裝形式。
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
Fuse-link
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.
Fuse-holder
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.
