Annotation of standard text IEC 61009-2-2-ed.2.0 :
IEC 61009-2-2:2024 applies to residual current operated circuit-breakers, with integral overcurrent protection, for household and similar uses (hereafter referred to as RCBOs), classified according to IEC 61009-1:2024, 4.1.2, 4.1.3, 4.1.4, 4.1.5 and 4.1.6. RCBOs according to this document are intended for voltages not exceeding 440 V AC with frequencies of 50 Hz, 60 Hz or 50/60 Hz and currents not exceeding 125 A and rated short-circuit capacities not exceeding 25 000 A for operation at 50 Hz or 60 Hz. This second edition cancels and replaces the first edition published in 1991. 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 4.1 for classification according to supply conditions; e) modification of Clause 6 for markings of RCBOs with a functional earth (FE); f) specific tests for operating characteristics of RCBO according to classifications 4.1.2, 4.1.3, 4.1.4, 4.1.5 and 4.1.6; g) specific test conditions for dielectric properties (9.7), temperature-rise (9.8), electrical and mechanical endurance (9.10), short-circuit tests (9.11), verification of trip-free (9.15), behaviour in the event of loss of the supply voltage (9.17), surge current tests (9.19), reliability (9.20), ageing (9.21) and temporary overvoltage TOV (9.24); h) additional tests for RCBOs with a terminal connected to the FE: Connecting capacity of FE terminal (9.200); Limitation of standing current in the FE (9.201).
