Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCBs) - Part 1: General rules

Scope

IEC 61008-1:2010+A1:2012+A2:2013 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:<br /> - complete revision of EMC sequences, including the new test T.2.6 already approved in IEC 61543;<br /> - clarification of RCDs current/time characteristics reported in Tables 1 and 2;<br /> - revision of test procedure for IΔn between 5 A and 200 A;<br /> - testing procedure regarding the 6mA d.c. current superimposed to the fault current;<br /> - improvement highlighting RCDs with multiple sensitivity;<br /> - tests for the use of RCCBs in IT systems.<br /> <b>This consolidated version consists of the third edition (2010), its amendment 1 (2012), its amendment 2 (2013) and the corrigendum of January 2014. Therefore, no need to order amendments in addition to this publication.</b>
