Scope

IEC 61009-1:2024, Clause 1 is applicable except for the first paragraph and the last paragraph,
which are replaced by the following, respectively:
This document 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, 4.1.1. 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 document applies in conjunction with IEC 61009-1:2024. It specifies requirements, tests
and test sequences to verify compliance and is used for certification purposes.
