ABB框架断路器按其使用范围分为高压断路器和低压断路器,高低压界线划分比较模糊,一般将3kV以上的称为高压电器。 低压断路器又称自动开关,俗称"空气开关"也是指低压断路器,它是一种既有手动开关作用,又能自动进行失压、欠压、过载、和短路保护的电器。它可用来分配电能,不频繁地启动异步电动机,对电源线路及电动机等实行保护,当它们发生严重的过载或者短路及欠压等故障时能自动切断电路,其功能相当于熔断器式开关与过欠热继电器等的组合。而且在分断故障电流后一般不需要变更零部件,已获得了广泛的应用。 ABB***式断路器又称框架式断路器:能接通、承载以及分断正常电路条件下的电流,也能在规定的非正常电路条件下接通.
