27、TROTECHNICAL COMMISSION _ LOW-VOLTAGE FUSES Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committee

28、s (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 Rep

29、orts, 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

30、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 agreement

31、s 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 a

32、re 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 int

33、ernational 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

34、 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 us

35、ers 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 ot

36、her 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.

37、 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 pate

38、nt rights. This consolidated version of IEC 60269-4 consists of the fifth edition (2009) documents 32B/535/FDIS and 32B/541/RVD and its amendment 1 (2012) documents 32B/579/CDV and 32B/586A/RVC. It bears the edition number 5.1. The technical content is therefore identical to the base edition and its

39、 amendment and has been prepared for user convenience. A vertical line in the margin shows where the base publication has been modified by amendment 1. Additions and deletions are displayed in red, with deletions being struck through. 60269-4 IEC:2009+A1:2012 5 International Standard IEC 60269-4 has

40、 been prepared by subcommittee 32B: Low-voltage fuses, of IEC technical committee 32: Fuses. This fifth edition cancels and replaces the fourth edition published in 2006. It constitutes a technical revision. The significant technical changes to the fourth edition are: the introduction of voltage sou

41、rce inverter fuse-links, including test requirements; coverage of the tests on operating characteristics for a.c. by the breaking capacity tests; the updating of examples of standardised fuse-links for the protection of semiconductor devices. This part is to be used in conjunction with IEC 60269-1:2

42、006, Low-voltage fuses Part 1: General requirements. This Part 4 supplements or modifies the corresponding clauses or subclauses of Part 1. Where no change is necessary, this Part 4 indicates that the relevant clause or subclause applies. Tables and figures which are additional to those in Part 1 ar

43、e numbered starting from 101. Additional annexes are lettered AA, BB, etc. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. A list of all parts of the IEC 60269 series, under the general title: Low-voltage fuses, can be found on the IEC website. The committee has

44、decided that the contents of the base publication and its amendments 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 reconfirmed, withdrawn, replaced by a

45、 revised edition, or amended. IMPORTANT The “colour inside” logo on the cover page of this publication indicates that it contains colours which are considered to be useful for the correct understanding of its contents. Users should therefore print this publication using a colour printer. 6 60269-4 I

46、EC:2009+A1:2012 LOW-VOLTAGE FUSES Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices 1 General IEC 60269-1 applies with the following supplementary requirements. Fuse-links for the protection of semiconductor devices shall comply with aIl requirements of IE

47、C 60269-1, if not otherwise indicated hereinafter, and shall also comply with the supplementary requirements laid down below. 1.1 Scope and object These supplementary requirements apply to fuse-links for application in equipment containing semiconductor devices for circuits of nominal voltages up to

48、 1 000 V a.c. or 1 500 V d.c. and also, in so far as they are applicable, for circuits of higher nominal voltages. NOTE 1 Such fuse-Iinks are commonly referred to as “semiconductor fuse-links”. NOTE 2 In most cases, a part of the associated equipment serves the purpose of a fuse-base. Owing to the g

49、reat variety of equipment, no general rules can be given; the suitability of the associated equipment to serve as a fuse- base should be subject to agreement between the manufacturer and the user. However, if separate fuse-bases or fuse-holders are used, they should comply with the appropriate requirements of IEC 60269-1. NOTE 3 IEC 60269-6 (Low-voltage fuses Part 6: Supplementar
