标准范围
IEC 61008-1:20 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剩余电流操作断路器，不包括过流保护（以下称为RCCB）。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，主要用于防止电击危险。这第三版取消并取代了1996年出版的第二版、修正案1（2002）和修正案2（2006）。本版构成技术修订版。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IEC 61543中已批准的新测试T.2.6；-澄清表1和表2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；-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；-测试RCCB在IT系统中的使用。
IEC 61008-1:2010 applies to residual current operated circuit-breakers functionally independent of, or functionally dependent on, line voltage, for household and similar uses, not incorporating overcurrent protection (hereafter referred to as RCCBs), 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, intended principally for protection against shock hazard. This third edition cancels and replaces the second edition published in 1996, amendment 1 (2002) and amendment 2 (2006). This edition 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 1 and 2;
- revision of test procedure for IΔn< /sub> between 5 A and 200 A;
- testing procedure regarding the 6mA d.c. current superimposed to the fault current;
- improvement highlighting RCDs with multiple sensitivity;
- tests for the use of RCCBs in IT systems.
