11、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 t
12、o 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
13、 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 condi
14、tions 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 Nati
15、onal 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 wa
16、y 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
17、 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. I
18、EC 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 it
19、s 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 oth
20、er 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
21、 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
22、 text of this standard is based on the following documents: FDIS Report on voting 23E/965/FDIS 23E/983/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/

The committee has decided that the conte
24、nts of this publication will remain unchanged until the stability date indicated on the IEC website under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. A bilingual vers

26、 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
27、 mating female connector for connecting electrical copper conductors according to the manufacturers 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 U
28、S. 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 a
29、nd including 4 mm2, or rigid stranded, having a cross-sectional area up to and including 2,5 mm2(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 The following documents, in whole or in par
30、t, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies.
