31、PE B RCCBs AND TYPE B RCBOs) 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 conc
32、erning 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)”). The
33、ir 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
34、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 re
35、levant 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 th
36、e 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 maxim
37、um 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 provides no marking procedure to indicate its approval and cannot be rendered responsible
38、 for any equipment declared to be in conformity with an IEC Publication. 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 com
39、mittees 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 Publicat
40、ions. 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 pat
41、ent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 62423 has been prepared by subcommittee 23E: Circuit-breakers and similar equipment for household use, of IEC technical committee 23: Electrical accessories. This International Sta
42、ndard is to be read in conjunction with the following standards: IEC 61008-1:1996, Residual current operated circuit-breakers without integral overcurrent protection for household and similar uses (RCCBs) Part 1: General rules Amendment 1(2002) Amendment 2 (2006) -,-,- 62423 IEC:2007 5 IEC 61009-1:1

46、gned according to IEC 61008-1 and IEC 61009-1 are suitable in most of the applications, however the use of new electronic technology in equipment may result in particular residual currents not covered in IEC 61008-1 or IEC 61009-1. This standard includes definitions, additional requirements and test
47、s for Type B RCCBs and Type B RCBOs to cover particular situations. The tests shall first be applied according to IEC 61008-1 for Type B RCCBs and according to IEC 61009-1 for Type B RCBOs. After completion of the tests given either in IEC 61008-1 or IEC 61009-1 the additional tests given in this st
48、andard shall be applied in order to show conformity to this standard (see Annex A or Annex B respectively). The number of samples to be submitted and test sequences to be applied for verification of conformity for RCCB Type B or RCBO Type B are given in Annex A or Annex B respectively. Smooth d.c. currents are unlikely to occur in a single phase supply with neutral. If nevertheless a smooth d.c. residual current can occur, a three-pole or four-pole dev
