标准摘要
[中文适用范围]： 本部分 IEC 62873 适用于配备铜制螺纹端子的设备，或含有至少 58% 铜（冷加工）或至少 50% 铜（其他加工）的合金，或其他耐腐蚀性不低于铜且机械性能不低于铜的金属或适当涂覆金属，用于未经处理的铝导体，或用于铜或铝导体的铝制螺纹端子。 本文件不涵盖铝导体或铝端子用于直流应用的情况。 本文件不包括柔性铝导体。 注1：柔性铝导体正在考虑中。 本文件不能单独使用，而是要与适用的产品标准一起使用。 在本文件中，铜包铝和镍包铝导体被视为铝导体。 注2：在奥地利、澳大利亚和德国，不允许使用铝制螺纹端子用于铜导体； 在奥地利和德国，不允许仅用于铝导体的端子； 在西班牙，不允许在家庭和类似安装（如办公室、商店）的最终电路中使用铝导体； 在丹麦，铝导体的最小横截面积为 16 mm²。 [外文原描述]： IEC 62873-3-3:2022 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its 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.
