IEC 62873-1:2017国际电工委员会；62873系列涵盖了与RCD（剩余电流装置）标准结合使用或用于制定RCD（剩余电流装置）标准的可用通用标准。IEC的这一部分；62873定义了基于新方法（以下称为模块和模块）制定标准时使用的方法和过程，旨在协调一系列标准，从而避免该系列标准中的错误、不一致或差异。本文件中考虑的标准系列包括RCCB（无过电流保护的剩余电流断路器）、RCBO（带过电流保护的剩余电流断路器）和剩余电流操作保护装置的一般安全要求（即IEC）； 61008-1，IEC；61009-1和IECTR；60755).

IEC 62873-1:2017 The IEC 62873 series covers available common standards intended to be used in conjunction with or for the preparation of RCD (residual current device) standards. This part of IEC 62873 defines the methodology and processes used when producing standards based on a new approach (hereafter referred to as blocks and modules) aiming at harmonizing a family of standards, thus avoiding mistakes, inconsistencies or discrepancies within this family of standards. The family of standards considered in this document consists of standards for RCCBs (Residual Current Circuit-Breakers without overcurrent protection), RCBOs (Residual Current Circuit-Breakers with overcurrent Protection), and general safety requirements for residual current operated protective devices (namely IEC 61008-1, IEC 61009-1 and IEC TR 60755).
