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.
