        一般選用原則:
        根據(jù)用途選擇斷路器的型式及極數(shù)。
        根據(jù)最大工作電流選擇斷路器的額定電流。
        根據(jù)需要選擇脫扣器的類型,附件的種類和規(guī)格。
        具體要求是:
        ① 斷路器的額定工作電壓≥線路額定電壓。
        ② 斷路器的額定短路通斷能力≥線路計算負載電流。
        ③ 斷路器的額定短路通斷能力≥線路中可能出現(xiàn)的最大短路電流(一般按有效值計算)。
        ④ 線路末端單相對地短路電流≥1.25倍斷路器瞬時(或短延時)脫扣整定電流。
