（2）額定電流
斷路器的額定電流與過電流脫扣器的額定電流應(yīng)大于線路計算負(fù)荷電流。當(dāng)按線路的計算電流選擇時，應(yīng)能滿足下式：
（4-10-6）
式中 ——低壓斷路器的額定電流，A；
——線路的計算電流或?qū)嶋H電流，A。
如果環(huán)境溫度低于+40℃，則電器產(chǎn)品溫度每低1℃，允許電流比額定電流值增加0.5%。但增加總數(shù)不得超過20％。
10.5 低壓斷路器
斷路器的保護(hù)定值
（1）長延時脫扣器的電流整定值，動作時間可以不小于10s；長延時脫扣器只能作過載保護(hù)。
（2）短延時脫扣器的電流整定值，動作時間約為0.1～0.4s；短延時脫扣器可以作短路保護(hù)，也可以作過載保護(hù)。
（3）瞬時脫扣器的電流整定值，其動作時間約為0.02s。瞬時脫扣器一般用作短路保護(hù)。
10.5 低壓斷路器
（3）瞬時過電流脫扣器的整定電流
瞬時脫扣器的動作時間為0.02s左右。
瞬時或短時過電流脫扣器的整定電流應(yīng)能躲開線路的尖峰電流。
1）負(fù)載是單臺電動機(jī)，整定電流按下式計算
