Annotation of standard text IEC 61009-1-ed.4.0 :
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.
