标准摘要
[中文适用范围]： 本国际标准适用于家庭和类似用途的安装在两极插座中或专门用于带或不带接地触点的剩余电流动作装置（RCD）（SRCD：插座剩余电流装置）。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。 [外文原描述]： IEC 62640:2011 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.
英文名称Residual current devices with or without overcurrent protection for socket-outlets for household and similar uses
