标准范围
IEC 61009-1:20 10适用于额定电压不超过440 V交流电的家用和类似用途的具有整体过电流保护的剩余电流操作断路器（以下简称RCBO）。额定频率为50赫兹、60赫兹或50/60赫兹，额定电流不超过125 A，额定短路容量不超过25 000 A，以50赫兹或60赫兹工作。第三版取消并取代了1996年出版的第二版、修正案1（2002年）和修正案2（2006年）。它构成技术修订。与上一版相比，此版本包括以下重大技术变更:-EMC序列的完整修订，包括已在IEC 61543中批准的新测试T.2.6；-澄清表2和表3中报告的RCDs电流/时间特性；-修订I Δ N在5A和200A之间的测试程序；-测试RCBO在资讯科技系统中的使用；-关于6mA d.c.的测试程序。叠加在故障电流上的电流；-突出具有多重灵敏度的RCD的改进；-与IEC 60898-1的一些一致性。
IEC 61009-1:2010 applies to residual current operated circuit breakers with integral overcurrent protection functionally independent of, or functionally dependent on, line voltage for household and similar uses (hereafter referred to as RCBOs), for rated voltages not exceeding 440 V a.c. 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 for operation at 50 Hz or 60 Hz. This third edition cancels and replaces the second edition, published in 1996, amendment 1 (2002) and amendment 2 (2006). It constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- complete revision of EMC sequences, including the new test T.2.6, already approved in IEC 61543;
- clarification of RCDs current/time characteristics reported in Tables 2 and 3;
- revision of test procedure for IΔn< /sub> between 5 A and 200 A;
- tests for the use of RCBOs in IT systems;
- testing procedure regarding the 6mA d.c. current superimposed to the fault current;
- improvement highlighting RCDs with multiple sensitivity;
- some alignments with IEC 60898-1.
