IEC 61008-2-2:2024 applies to residual current operated circuit-breakers, without integral overcurrent protection, for household and similar uses (hereafter referred to as RCCBs), classified according to IEC 61008-1:2024, 4.1.2, 4.1.3, 4.1.4, 4.1.5 and 4.1.6. RCCBs 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, intended principally for protection against shock hazard.
This second edition cancels and replaces the first edition published in 1990. 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 RCCBs with a functional earth (FE);
f) specific tests for operating characteristics of RCCBs 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 case 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 RCCBs with a terminal connected to the FE: connecting capacity of FE terminal (9.200)and limitation of standing current in the FE (9.201).
