30、ional 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 electron

31、ic 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;

32、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 Stand

33、ardization (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 re

34、presentation 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,

35、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 pub

36、lications. 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 ar

37、eas, 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 inclu

38、ding 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 relia

39、nce 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 el

40、ements 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. The main task of IEC technical committees is to prepare International Standards. However, a technical committee may propose the publication of a techni

41、cal report when it has collected data of a different kind from that which is normally published as an International Standard, for example “state of the art“. IEC 61439-0, which is a technical report, has been prepared by subcommittee 17D: Low- voltage switchgear and controlgear assemblies, of IEC te

42、chnical committee 17: Switchgear and controlgear. This second edition cancels and replaces the first edition published in 2010. It constitutes a technical revision. This second edition includes the following significant technical changes with respect to the previous edition: alignment with IEC 61439

43、-1:2011; alignment of Annex B with Annex AA of IEC 61439-2:2011; alignment of Table C.1 with Table BB.1 of IEC 61439-2:2011; 6 TR 61439-0 IEC:2013(E) addition of a new Annex D regarding IEC 61439-3; addition of a new Annex E regarding IEC 61439-4; addition of a new Annex G regarding IEC 61439-6; gen

44、eral editorial review. The text of this technical report is based on the following documents: Enquiry draft Report on voting 17D/458/DTR 17D/467A/RVC Full information on the voting for the approval of this technical report can be found in the report on voting indicated in the above table. This publi

45、cation has been drafted in accordance with the ISO/IEC Directives, Part 2. The readers attention is drawn to the fact that Annex I lists all of the “in-some-country” clauses on differing practices of a less permanent nature relating to the subject of this Technical Report. A list of all parts of the

46、 IEC 61439 series, under the general title Low-voltage switchgear and controlgear assemblies, can be found on the IEC web site. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the IEC web site under “http:/webstore.iec.ch“ i

47、n 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 version of this publication may be issued at a later date. TR 61439-0 IEC:2013(E) 7 INTRODUCTION For the purposes of this technical rep

48、ort, the user is the party who specifies or selects the ASSEMBLY characteristics. The user may be the same party as the one who will use and operate the ASSEMBLY, or someone acting on their behalf. The aim of this technical report is to provide the user with guidance on the specification that should

49、 be provided in order to achieve the desired design of an assembly. Throughout this technical report, the term ASSEMBLY is used for a low-voltage switchgear and controlgear assembly. The term “manufacturer” refers to the ASSEMBLY manufacturer unless specifically noted otherwise. The purpose of the IEC 61439 series of standards is to harmonize as far as practicable, all the general rules and requirements that apply to ASSEMBLIES. The series further seeks, in order to obtain uniformit
