IEC 62873-3-1:20 20作为IEC 62873-3-1:20 20 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 62873-3-1:20 20适用于配备电流不超过40 A的无螺丝型端子的设备，主要适用于连接未准备好的铜导线？截面最大为10 mm2。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:-修改范围以覆盖高达40A的无螺丝型端子；-修改范围以解决除RCD之外的其他设备；-修改表1以涵盖高达40A的额定电流；-修改8.1，使IEC 62873-3-1除了用于RCD的标准之外，还可以被其他产品标准引用；-对9.1进行修改，使得IEC 62873-3-1除了用于RCD的标准之外，还可以被其他产品标准引用。

IEC 62873-3-1:2020 is available as IEC 62873-3-1:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

IEC 62873-3-1:2020 applies to devices equipped with screwless-type terminals for current not exceeding 40 A, primarily suitable for connecting unprepared copper conductors of cross？section up to 10 mm2. 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 cover screwless-type terminals up to 40 A;
- Modification of scope to address other devices in addition to RCDs;
- Modification of Table 1 to cover rated currents up to 40 A;
- Modification of 8.1 so that IEC 62873-3-1 can be referred to by other product standards in addition to those for RCDs;
- Modification of 9.1 so that IEC 62873-3-1 can be referred to by other product standards in addition to those for RCDs.
