标准摘要
[中文适用范围]： 本文件适用于家用和类似用途的带过电流保护的剩余电流动作断路器（以下简称RCBO），根据IEC 61009-1:2024，4.1.1分类。本文件中的RCBO适用于交流电压不超过440V，频率为50Hz、60Hz或50/60Hz，电流不超过125A，额定短路容量不超过25000A（在50Hz或60Hz下运行）。本文件与IEC 61009-1:2024一起使用，规定了验证符合性的要求、测试和测试序列，并用于认证目的。 [外文原描述]： IEC 61009-2-1:2024 applies to residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (hereafter referred to as RCBOs), classified according to IEC 61009-1:2024, 4.1.1. RCBOs according to this document are intended for voltages not exceeding 440 V AC with frequencies of 50 Hz, 60 Hz or 50/60 Hz and currents not exceeding 125 A and rated short‑circuit capacities not exceeding 25 000 A for operation at 50 Hz or 60 Hz. This second edition cancels and replaces the first edition published in 1991. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) harmonization of all clauses between the IEC 61008, IEC 61009 and IEC 60755 series using blocks and modules approach; b) harmonization of all tables and figures between the IEC 61008, IEC 61009 and IEC 60755 series; c) terms and definitions are now referred to IEC 62873-2; d) modification of Subclause 4.1 for classification according to supply conditions; e) specific tests for operating characteristics (9.9) of RCBO according to classification 4.1.1; f) specific test conditions for temperature-rise (9.8), verification of trip-free (9.15), surge current tests (9.19), reliability (9.20) and ageing (9.21).
