标准摘要
[中文适用范围]: 本部分 IEC 62873 适用于配备无螺纹端子的 RCD,用于不超过 20 A 的电流,主要适用于连接横截面不超过 4 mm² 的未加工(见 3.5)铜导体。 本部分 IEC 62873 不能单独使用,但如果 RCD 配备无螺纹端子,则应与 RCD 产品标准(IEC 61008-1 或 IEC 61009-1)一起应用。 注 - 在 AT、CZ、DK、NL、NO、PO、PT 和 CH 中,无螺纹端子的使用电流上限为 16 A。 本文件适用于配备无螺纹端子的设备,用于不超过 40 A 的电流,主要适用于连接横截面不超过 10 mm² 的未加工铜导体。 本文件不能单独使用,但应与适用的产品标准一起应用,其中引用了本文件。 注 1 在 CZ、DK、NL、PO 和 CH 中,无螺纹端子的使用电流上限为 16 A。 注 2 在 JP 中,无螺纹端子的使用电流上限为 30 A。 注 3 制造商可以在其文档中声明允许使用加工导体的特定条件。 在本文件中,无螺纹端子称为端子,铜导体称为导体。 [外文原描述]: IEC 62873-3-1:2020 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 62873-3-1:2020 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.
