採用額定動作電流不超過500mA的剩餘電流斷路器,可以在出現引燃火災所需的能量前,就發出警報或斷開電路排除故障。為防止電弧性接地故障引起的電氣火災,在線路上裝用帶剩餘電流保護功能的斷路器是一項重要的防火災措施。其剩餘電流保護功能對建築物的電弧性接地故障引起的電氣火災進行防範。為切斷建築物內的電弧性大多接地故障,在電源進線端也應裝用剩餘電流斷路器。GB50096《住宅設計規範》,規定了每幢住宅樓的總電源進線斷路器,應帶有剩餘電流保護功能的明確規定。因多數用戶不懂得用電知識,又無專業電工進行維護管理,住宅電氣火災發生較多。據近年統計,我國住宅電氣火災佔電氣火災總數的一半以上,所以這一規定是十分必要的。
