IEC 61008-1 Ed. 3.2 b – Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCBs) – Part1: General rules CONSOLIDATED EDITION

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 notexceeding 125 A, intended principally for protection against shockhazard. This third edition cancels and replaces the second editionpublished in 1996, amendment 1 (2002) and amendment 2 (2006). Thisedition 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.2.6already approved in IEC 61543;
– clarification of RCDs current/time characteristics reported in Tables 1 and 2;
– revision of test procedure for I_{Δn< /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.
This consolidated version consists of the third edition (2010), its amendment 1 (2012) and its amendment 2 (2013). Therefore, no need to order amendments in addition to this publication.}
