标准摘要
[中文适用范围]： IEC 62640:2011+A1:2015 适用于家用和类似用途的剩余电流动作装置 (RCD)，或专门用于两极插座，带或不带接地触点（SRCD：插座剩余电流）当前设备）。根据该标准，SRCD 旨在用于单相系统，例如相到中性线、相到相或相到接地中间导体。 SRCD 仅旨在为 SRCD 下游提供额外保护。 SRCD 适用于在 SRCD 上游已确保故障保护（间接接触保护）的电路中。该合并版本由第一版（2011年）及其修订1（2015年）组成。因此，无需对本出版物进行修订。 [外文原描述]： IEC 62640:2011+A1:2015 applies to residual current-operated devices (RCD) incorporated in, or specifically intended for use with two pole socket-outlets, with or without earthing contact for household and similar uses (SRCD: socket-outlet residual current devices). SRCDs, according to this standard, are intended to be used in single phase systems such as phase to neutral or phase to phase or phase to earthed middle conductor. SRCDs are only intended to provide additional protection downstream of the SRCD. SRCDs are intended for use in circuits where the fault protection (indirect contact protection) is already assured upstream of the SRCD. This consolidated version consists of the first edition (2011) and its amendment 1 (2015). Therefore, no need to order amendment in addition to this publication.
