(Main)Low-voltage fuses - Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices
Low-voltage fuses - Part 4: Supplementary requirements for fuse-links for the protection of semiconductor devices
IEC 60269-4:2009 is to be used in conjunction with IEC 60269-1. This Part 4 supplements or modifies the corresonding clauses or subclauses of Part 1. Fuse-links for the protection of semiconductor devices shall comply with aIl requirements of IEC 60269-1, if not otherwise indicated hereinafter, and shall also comply with the supplementary requirements laid down below. 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 source 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.
Fusibles basse tension - Partie 4: Exigences supplémentaires concernant les éléments de remplacement utilisés pour la protection des dispositifs à semiconducteurs
La CEI 60269-4:2009 doit être utilisée conjointement avec la quatrième édition de la CEI 60269-1. Cette Partie 4 complète ou modifie les articles ou paragraphes correspondant de la Partie 1. Sauf indication contraire dans le texte qui suit, les éléments de remplacement utilisés pour la protection des dispositifs à semiconducteurs doivent répondre à l'ensemble des exigences énoncées dans la CEI 60269-1 ainsi qu'aux exigences supplémentaires fixées ci-après. Cette cinquième édition annule et remplace la quatrième édition, parue en 2006. Elle constitue une révision technique. Les modifications techniques significatives par rapport à la quatrième édition sont:
- l'introduction des éléments de remplacement pour onduleur à source de tension, y compris les exigences d'essai;
- les essais sur les caractéristiques de fonctionnement en courant alternatif, maintenant couverts par les essais de pouvoir de coupure;
- la mise à jour des exemples d'éléments de remplacement normalisés pour la protection des dispositifs à semiconducteurs.

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 concerning 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)”). 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 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 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 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 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
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 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 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 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 may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60269-4 has been prepared by subcommittee 32B: Low-voltage
fuses, of IEC technical committee 32: Fuses.
The text of this standard is based on the following documents:
FDIS Report on voting
32B/535/FDIS 32B/541/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.

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 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 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 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 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 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 are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the
