标准摘要
[中文适用范围]： 本国际标准适用于家用和类似用途的、具有功能独立于或依赖于线电压的集成过流保护的剩余电流动作断路器（以下简称RCBO），额定电压不超过440Vac，额定电流不超过440Vac。在 50 Hz 或 60 Hz 下运行时，额定短路容量不超过 125 A，额定短路容量不超过 25 000 A。 2003 年 5 月勘误的内容已包含在本副本中。该合并版本由第二版（1996年）、修订案1（2002年）和修订案2（2006年）组成。因此，除了本出版物之外，无需订购修订。 [外文原描述]： This International Standard applies to residual current operated circuit breakers with integral overcurrent protection functionally independent of, or functionally dependent on, line voltage for household and similar uses (hereafter referred to as RCBOs), for rated voltages not exceeding 440 V a.c., rated currents not exceeding 125 A and rated short circuit capacities not exceeding 25 000 A for operation at 50 Hz or 60 Hz. The contents of the corrigendum of May 2003 have been included in this copy. This consolidated version consists of the second edition (1996), its amendment 1 (2002) and its amendment 2 (2006). Therefore, no need to order amendments in addition to this publication.
