High-voltage fuses - Part 1: Current-limiting fuses

IEC 60282-1:2009 applies to all types of high-voltage current-limiting fuses designed for use outdoors or indoors on alternating current systems of 50 Hz and 60 Hz and of rated voltages exceeding 1 000 V. The changes introduced by this new edition are only editorial.

Hochspannungssicherungen – Teil 1: Strombegrenzende Sicherungen

Fusibles à haute tension - Partie 1: Fusibles limiteurs de courant

La CEI 60268-1:2009 s'applique à tous les types de fusibles à haute tension limiteurs de courant destinés à être utilisés à l'extérieur ou à l'intérieur sur des réseaux à courant alternatif 50 Hz et 60 Hz et dont les tensions assignées sont supérieures à 1 000 V. Les modifications introduites par cette nouvelle édition sont uniquement éditoriales.

Visokonapetostne varovalke - 1. del: Tokovno omejilne varovalke (IEC 60282-1:2009)

Ta del IEC 60282 velja za vse tipe visoko napetostnih tokovno omejilnih varovalk, zasnovanih za notranjo ali zunanjo uporabo na sistemih z izmeničnim tokom 50 Hz in 60Hz in ocenjenih napetosti, ki presegajo 1000 V. Nekatere varovalke so priskrbljene z taljivimi vložki varovalk opremljenimi z kazalnimi napravami ali zapirali. Te varovalke so zajete s tem standardom, vendar pravilno delovanje zapirala v kombinaciji s sprožilnim mehanizmom preklopne naprave ni zajeto z tem standardom; glej IEC 62271-105.

INTERNATIONAL ELECTROTECHNICAL COMMISSION ____________
HIGH-VOLTAGE FUSES –
Part 1: Current-limiting fuses

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 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 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 60282-1 has been prepared by subcommittee 32A: High-voltage fuses, of IEC technical committee 32: Fuses. This seventh edition cancels and replaces the sixth edition published in 2005. The changes introduced by this new edition are only editorial. The text of this standard is based on the following documents: FDIS Report on voting 32A/274/FDIS 32A/277/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. SIST EN 60282-1:2010

A list of all parts of IEC 60282 series, under the general title High-voltage fuses, can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the maintenance result 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
