标准摘要
[中文适用范围]: IEC 62873 的本部分适用于配备无螺丝端子的 RCD,电流不超过 20 A,主要适用于连接横截面最大为 4 mm2 的未制备(见 3.5)铜导体。 IEC 62873 的这一部分不能单独使用,但如果 RCD 配备无螺丝端子,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,无螺钉端子使用的电流上限为 16 A。在 IEC 62873 的本部分中,无螺钉端子称为端子,铜导体称为端子。简称导体。 [外文原描述]: IEC 62873-3-1:2016(E) applies to RCDs equipped with screwless terminals, for current not exceeding 20 A primarily suitable for connecting unprepared (see 3.5) copper conductors of cross-section up to 4 mm2. This part of IEC 62873 cannot be used alone but it is intended to be applied together with an RCD product standard (IEC 61008-1 or IEC 61009-1) if an RCD is equipped with screwless terminals.
