摘　　要：根据低压电器的特性,主要分析了常用低压电器的组合类型和组合原则,其中包括熔断器(FU)+接触器(KM)+过热负荷继电器(KR)组合、断路器(QF)+KM+KR组合、QF+KR组合、FU+QF+KR组合。通过对FU与QF进行比较,并提供了按样本资料偏于安全的实用组合方法。This paper mainly analyzed the general combination type and principle based on the characteristic of low voltage electric devices,separately including FU（fuse）＋KM（contactor）＋KR（overheating load relay）,QF （circuit breaker）＋KM＋KR,QF＋KM,FU＋QF＋KM combinations,comparison between fuse and QF,as well as practically combination method in view of safety purpose based on device catalog and manual.
