家用和类似用途的剩余电流动作断路器 第 3-1 部分：外部铜导体用无螺纹型端子的设备的特殊要求

[中文适用范围]： 本文件适用于配备无螺丝型端子的设备，电流不超过40 A，主要适用于连接截面不超过10 mm²的非预制铜导体。本文件不能单独使用，而是要与适用的产品标准一起应用。 注1：在CZ、DK、NL、PO和CH，无螺丝型端子的电流上限为16 A。 注2：在JP，无螺丝型端子的电流上限为30 A。 注3：制造商可以在其文档中声明允许使用预制导体的特定条件。 在本文件中，无螺丝型端子称为端子，铜导体称为导体。 [外文原描述]： 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.
