中電氣設備選擇不(bu)當造成的(de)(de)常見(jian)錯誤：生產過(guo)程(cheng)中交(jiao)(jiao)流(liu)接觸器的(de)(de)體積選擇不(bu)當，不(bu)同(tong)組的(de)(de)插座控制電路安裝了相同(tong)體積的(de)(de)交(jiao)(jiao)流(liu)接觸器，三相負載的(de)(de)差異不(bu)完全考慮過(guo)的(de)(de)。在平衡狀態下，不(bu)能在所有正常模型中選擇某些組的(de)(de)輸出交(jiao)(jiao)流(liu)接觸器的(de)(de)電流(liu)水平。基本上，電流(liu)水平是通過(guo)一個步驟選擇的(de)(de)，該步驟會導致交(jiao)(jiao)流(liu)接觸器在高溫天氣下運行(xing)期間燒斷(duan)。
