22、ion (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
23、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 int
24、erested 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
25、 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 interest
26、ed 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
27、 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 betw
28、een 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 co
29、nformity. 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 me
30、mbers 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
31、 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
32、 may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard IEC 61439-2 has been prepared by subcommittee 17D: Low-voltage switchgear and controlgear assemblies, of IEC technical committee 17: Switchgear and controlgea
33、r. This second edition cancels and replaces the first edition published in 2009. It constitutes a technical revision. This second edition includes the following significant technical changes with respect to the last edition of IEC 61439-2: clarification of the scope; revision of requirements for wit
34、hdrawable and removable parts; revision of mechanical impact test (10.2.6); extension of Table 101; 4 61439-2 IEC:2011 review of Table BB.1 to reflect modified requirements and verifications; general editorial review. The text of this standard is based on the following documents: FDIS Report on voti
35、ng 17D/440/FDIS 17D/445/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/IEC Directives, Part 2. This standard is to be read in conjunction with IEC 614
36、39-1. The provisions of the general rules dealt with in IEC 61439-1 (hereinafter referred to as Part 1) are only applicable to this standard insofar as they are specifically cited. When this standard states “addition”, “modification” or “replacement”, the relevant text in Part 1 is to be adapted acc
37、ordingly. Subclauses that are numbered with a 101 (102, 103, etc.) suffix are additional to the same subclause in Part 1. Tables and figures in this Part 2 that are new are numbered starting with 101. New annexes in this Part 2 are lettered AA, BB, etc. In this standard, terms written in small capit
38、als are defined in Clause 3. NOTE Throughout the IEC 61439 series of standards, the term ASSEMBLY (see 3.1.1 of Part 1) is used for a low- voltage switchgear and controlgear assembly. A list of all parts of the IEC 61439 series, under the general title Low-voltage switchgear and controlgear assembli
39、es can be found on the IEC website. 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“ in the data related to the specific publication. At this date, the publication will be reconf
40、irmed, withdrawn, replaced by a revised edition, or amended. 61439-2 IEC:2011 5 LOW-VOLTAGE SWITCHGEAR AND CONTROLGEAR ASSEMBLIES Part 2: Power switchgear and controlgear assemblies 1 Scope NOTE 1 Throughout this part, the abbreviation PSC-ASSEMBLY (see 3.1.101) is used for a power switchgear and co
41、ntrolgear ASSEMBLY. This part of IEC 61439 defines the specific requirements of power switchgear and controlgear assemblies (PSC-ASSEMBLIES) as follows: ASSEMBLIES for which the rated voltage does not exceed 1 000 V in case of a.c. or 1 500 V in case of d.c.; stationary or movable ASSEMBLIES with or
42、 without enclosure; ASSEMBLIES intended for use in connection with the generation, transmission, distribution and conversion of electric energy, and for the control of electric energy consuming equipment; ASSEMBLIES designed for use under special service conditions, for example in ships and in rail
43、vehicles provided that the other relevant specific requirements are complied with; NOTE 2 Supplementary requirements for ASSEMBLIES in ships are covered by IEC 60092-302. ASSEMBLIES designed for electrical equipment of machines. Supplementary requirements for ASSEMBLIES forming part of a machine are
44、 covered by the IEC 60204 series. This standard applies to all ASSEMBLIES whether they are designed, manufactured and verified on a one-off basis or fully standardised and manufactured in quantity. The manufacture and/or assembly may be carried out other than by the original manufacturer (see 3.10.1
45、). This standard does not apply to individual devices and self-contained components, such as motor starters, fuse switches, electronic equipment, etc. which will comply with the relevant product standards.This standard does not apply to the specific types of ASSEMBLIES covered by other parts of IEC
46、61439. For ASSEMBLIES not covered by other parts this part applies. 2 Normative references This clause of Part 1 is applicable except as follows.
