RESIDUAL CURRENT-OPERATED PROTECTIVE DEVICES (RCDs) FOR
HOUSEHOLD AND SIMILAR USE – ELECTROMAGNETIC COMPATIBILITY

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
IEC 61543 has been prepared by subcommittee 23E: Circuit-breakers and similar equipment
for household use, of IEC technical committee 23: Electrical accessories. It is an International
Standard.
This second edition cancels and replaces the first edition published in 1995, Amendment 1:2004
and Amendment 2:2005. This edition constitutes a technical revision.
This edition includes the following significant changes with respect to the previous edition:
a) some editorial modifications were introduced to comply to the ISO/IEC Directives
Part 2:2021, e.g. introduction of Clause 3 – Terms and Definitions and renumbering
of the whole document. In particular, the numbering of performance criteria has been
changed (5.1.1, 5.1.2 become A, B, etc.);
b) some technical improvements:
• Modification of scope and addition of Clause 6 and Clause 7 to enable the use
of this document as a guideline for the preparation of EMC requirements and
tests for other product standards under the scope of SC 23E;
• Requirements for voltage dips and interruptions added;

– 4 – IEC 61543:2022  IEC 2022
• Repetition rate for burst-test, defined at 5 kHz;
• Surge test: Specifying impulse voltage application point and adding of voltages
2 kV, 1 kV and 0,5 kV to test T 5b;
• Radiated radio-frequency electromagnetic field: Adding of frequency range
1,4 GHz to 6 GHz and specifying frequencies for the test at 1,25 I ;
Δn
• Conducted, common mode disturbances in the frequency range 0 Hz to 150 kHz:
Specifying frequencies for the test at 1,25 I ;
Δn
• Electrostatic discharges: Change of performance criteria from 5.1.3 to B.
The text of this International Standard is based on the following documents:
