采用额定动作电流不超过500mA的剩余电流断路器,可以在出现引燃火灾所需的能量前,就发出警报或断开电路排除故障。为防止电弧性接地故障引起的电气火灾,在线路上装用带剩余电流保护功能的断路器是一项重要的防火灾措施。其剩余电流保护功能对建筑物的电弧性接地故障引起的电气火灾进行防范。为切断建筑物内的电弧性大多接地故障,在电源进线端也应装用剩余电流断路器。GB50096《住宅设计规范》,规定了每幢住宅楼的总电源进线断路器,应带有剩余电流保护功能的明确规定。因多数用户不懂得用电安全知识,又无专业电工进行维护管理,住宅电气火灾发生较多。据近年统计,我国住宅电气火灾占电气火灾总数的一半以上,所以这一规定是十分必要的。
在进线处安装带过载保护、短路保护、剩余电流保护于一体的多功能低压断路器,不仅可以保护线路、保护设备,而且还可防止因接地故障引起的电气火灾。
