标准摘要
[中文适用范围]： 本文件规定了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RCBOs）的一般要求和试验，适用于额定工作电压不超过440V交流电，额定频率为50Hz、60Hz或50/60Hz，额定电流不超过125A，额定短路容量不超过25000A的RCBOs。RCBOs旨在提供故障保护（以前称为防止间接接触的保护），安装的裸露导电部分连接到适当的地电极。这些设备还旨在保护建筑物和类似应用的布线装置中的过电流。它们还用于提供由于持续接地故障电流引起的火灾危险的保护。 [外文原描述]： IEC 61009-1:2024 gives general requirements and tests for residual current operated circuit‑breakers with integral overcurrent protection for household and similar uses (hereafter referred to as RCBOs), for rated operational voltages not exceeding 440 V AC, with rated frequencies of 50 Hz, 60 Hz or 50/60 Hz and rated currents not exceeding 125 A and rated short‑circuit capacities not exceeding 25 000 A. This fourth edition cancels and replaces the third edition published in 2010, Amendment 1:2012 and Amendment 2:2013. 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) new Subclauses 8.17 and 9.24 for requirements and tests for the resistance to temporary overvoltages (TOV); f) improvement of Subclause 9.7 for test of dielectric properties; g) tests for screwless, flat-quick terminals and aluminium conductors are now referred to in the IEC 62873-3 series.
