产品简述
DW15-630万能式断路器(以下简称断路器)及DWX15-630万能式限流断路器(以下简称限流断路器)主要用于交流50Hz,额定电流至630A,额定工作电压380V的配电网络中,用来分配电能和保护线路及电源设备的过载、欠电压、短路,也可用来保护电动机的过载、欠电压和短路或用于660V的配电网络中,用作上述保护。此外断路器还可以用于1140V的配电网络,作上述保护。
断路器(限流断路器)除固定式结构外,还具有抽屉式结构,在正常条件下可作为线路的不频繁转换和电动机的不频繁起动之用。由于断路器具有二段或三段保护特性,可以对电网作选择性保护。抽屉式断路器(抽屉式限流断路器)在主回路和二次回路中均采用了插入式结构,省略了固定式所必须的隔离器,做到一机二用,提高了使用的经济性,同时给操作与维护带 来了很大的方便,增加了安全性、可靠性。特别是本抽屉座的主回路触刀座,可与NT3型熔断器触刀座通用,这样在应急状态下可直接插入熔断器供电。
限流断路器由于具有限流特性,特别适用于可能出现大短路电流的网络。
断路器按GB14048.2设计,制造与检验。
