（2）額定電流
斷路器的額定電流與過(guò)電流脫扣器的額定電流應(yīng)大于線路計(jì)算負(fù)荷電流。當(dāng)按線路的計(jì)算電流選擇時(shí)，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(jì)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(guò)20％。
10.5 低壓斷路器
斷路器的保護(hù)定值
（1）長(zhǎng)延時(shí)脫扣器的電流整定值，動(dòng)作時(shí)間可以不小于10s；長(zhǎng)延時(shí)脫扣器只能作過(guò)載保護(hù)。
（2）短延時(shí)脫扣器的電流整定值，動(dòng)作時(shí)間約為0.1～0.4s；短延時(shí)脫扣器可以作短路保護(hù)，也可以作過(guò)載保護(hù)。
（3）瞬時(shí)脫扣器的電流整定值，其動(dòng)作時(shí)間約為0.02s。瞬時(shí)脫扣器一般用作短路保護(hù)。
10.5 低壓斷路器
（3）瞬時(shí)過(guò)電流脫扣器的整定電流
瞬時(shí)脫扣器的動(dòng)作時(shí)間為0.02s左右。
瞬時(shí)或短時(shí)過(guò)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(tái)電動(dòng)機(jī)，整定電流按下式計(jì)算
