IEC 62873-3-3:20 22可作为IEC 62873-3-3:20 22 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。IEC 62873-3-3:20 22适用于配备铜（或含有至少58%铜（如果冷加工）或至少50%铜（如果以其他方式加工）的合金、或其他金属或适当涂层的金属、耐腐蚀性不低于铜且机械性能不低于铜）的螺钉型端子的设备，用于未处理的铝导体，或用于铜或铝导体的螺钉型端子。这第二版取消并取代了2016年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-修改范围以解决除RCD之外的其他设备；-修改第8条，使IEC 62873-3-3除了用于RCD的标准之外，还可以被其他产品标准引用；-修改9.1，使IEC 62873-3-3除了用于RCD的标准之外，其他产品标准也可以参考。

IEC 62873-3-3:2022 is available as IEC 62873-3-3:2022 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62873-3-3:2022 applies to devices equipped with screw-type terminals of copper - or of alloys containing at least 58 % of copper (if worked cold) or at least 50 % of copper (if worked otherwise), or of other metal or suitably coated metal, no less resistant to corrosion than copper and having mechanical properties no less suitable – for use with untreated aluminium conductors, or with screw-type terminals of aluminium material for use with copper or aluminium conductors. This second edition cancels and replaces the first edition published in 2016. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- Modification of scope to address other devices in addition to RCDs;
- Modification of Clause 8 so that IEC 62873-3-3 can be referred to by other product standards in addition to those for RCDs;
- Modification of 9.1 so that IEC 62873-3-3 can be referred to by other product standards in addition to those for RCDs.
