一般来说，具有过载长延时、短路短延时和短路瞬动三段保护功能的断路器，能实现选择性保护，大多数主干线(包括变压器的出线端)都采用它作主保护开关。不具备短路短延时功能的断路器(仅有过载长延时和短路瞬动二段保护)，不能作选择性保护，它们只能使用于支路。具有三段保护的断路器，偏重于它的运行短路分断能力值，而使用于分支线路的断路器，应确保它有足够的极限短路分断能力值。 无论是哪种断路器，虽然都具备Icu和Ics这两个重要的技术指标。但是，作为支线上使用的断路器，可以仅满足额定极限短路分断能力即可。现在出现的较普遍的偏颇是宁取大，不取正合适，认为取大保险。但取得过大，会造成不必要的浪费(同类型断路器，其H型—高分断型，比S型—普通型的价格要贵1.3倍～1.8倍)。因此支线上的断路器没有必要一味追求它的运行短路分断能力指标。而对于干线上使用的断路器，不仅要满足额定极限短路分断能力的要求，同时也应该满足额定运行短路分断能力的要求，如果仅以额定极限短路分断能力Icu来衡量其分断能力合格与否，将会给用户带来不安全的隐患。
