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.
International Standard IEC 62873-3-2 has been prepared by subcommittee 23E: Circuit
breakers and similar equipment for household use, of IEC technical committee 23: Electrical
accessories.
The text of this standard is based on the following documents:

RESIDUAL CURRENT OPERATED CIRCUIT-BREAKERS
FOR HOUSEHOLD AND SIMILAR USE –

Part 3-2: Particular requirements for RCDs
with flat quick-connect terminations

1 Scope
This part of IEC 62873 applies to RCDs equipped with flat quick-connect terminations
consisting of a male tab (see 3.2) with nominal width 6,3 mm and thickness 0,8 mm, to be
used with a mating female connector for connecting electrical copper conductors according to
the manufacturer's instructions, for rated currents up to and including 16 A.
NOTE The use of RCDS with flat quick-connect terminations for rated currents up to and including 20 A is
accepted in BE, FR, IT, ES, PT and US.
This part of IEC 62873 cannot be used alone but is intended to be applied together with an
RCD product standard (IEC 61008-1 or IEC 61009-1) if an RCD is equipped with flat quick-
connect terminations.
The connectable electrical copper conductors are flexible, having a cross-sectional area up to
and including 4 mm , or rigid stranded, having a cross-sectional area up to and including
2,5 mm (AWG equal to or greater than 12).
This part of IEC 62873 applies exclusively to RCDs having male tabs as an integral part of the
device.
2 Normative references
