Residual current operated circuit-breakers with integral overcurrent protection for household and similar uses (RCBOs) - Part 1: General rules
OVERVIEW
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.
