    RT14系列圆筒形帽熔断器

    RT14系列圆筒形帽熔断器适用于额定电压交流380V,额定电流至100A的配电装置中作过载保护和短路保护。

    本系列熔断器由高分断能力圆筒形帽熔断体和熔断器支持件组成。
    熔断体
    熔断体的熔体两端焊接在圆筒形端帽上,接近熔体的最热部位配置适量易熔合金,以使熔断体有较低的动作温度和耗散功率,使熔断体能适应过载而几乎不老化。
    熔断器支持件
    熔断器支持件是熔断器底座和载熔件的组合。底座由插座、接线端子和绝缘座等部件组成;载熔件是用来装卸和载运熔断体的熔断器可动绝缘部件。
    熔断器支持件有螺钉固定和电器安装轨等安装形式。
    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.
