IEC 61008-2-1:2024 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, 4.1.1. 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:
- harmonization of all clauses between the IEC 61008, IEC 61009 and IEC 60755 series using blocks and modules approach;
- harmonization of all tables and figures between the IEC 61008, IEC 61009 and IEC 60755 series;
- terms and definitions are now referred to IEC 62873-2;
- modification of 4.1 for classification according to supply conditions;
- specific tests for operating characteristics (9.9) of RCCB according to classification 4.1.1;
- specific test conditions for temperature-rise (9.8), verification of trip-free (9.15), surge current tests (9.19), reliability (9.20) and ageing (9.21).
