Part 102: Alternating current disconnectors
and earthing switches
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, 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 62271-102 has been prepared by subcommittee 17A: High-voltage
switchgear and controlgear, of IEC technical committee 17: Switchgear and controlgear.
This first edition cancels and replaces the third edition of IEC 60129 published in 1984,
amendment 1 (1992) and amendment 2 (1996) and constitutes a technical revision. In
addition, it replaces IEC 61128, IEC 61129 and IEC 61259, which are hereby withdrawn and
cancelled. A reference table is provided at the end of this foreword.
This bilingual version (2003-08) replaces the English version.
The text of this standard is based on the following documents:
FDIS Report on voting
17A/617/FDIS 17A/619/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.

62271-102 © IEC:2003 – 15 –
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annexes A, B, C, E and F form an integral part of this standard.
Annex D is for information only.
This standard should be read in conjunction with IEC 60694, second edition, published in
1996, to which it refers and which is applicable, unless otherwise specified. In order to
simplify the indication of corresponding requirements, the same numbering of clauses and
subclauses is used as in IEC 60694. Additional subclauses are numbered from 101.
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
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
The contents of the corrigenda of April 2002, May 2003 and February 2005 have been included
in this copy.

COMMON NUMBERING OF IEC 62271 PUBLICATIONS FALLING UNDER
THE RESPONSIBILITY OF SUBCOMMITTEES SC 17A AND SC 17C
In accordance with the decision taken at the joint SC 17A/SC 17C meeting in Frankfurt, June
1998 (item 20.7 of 17A/535/RM), a common numbering system has been established for the
publications falling under the responsibility of SC 17A and SC 17C. IEC 62271 – High-voltage
switchgear and controlgear is the publication number and main title element for the common
publications.
The numbering of these publications will apply the following principle.
a) Common standards prepared by SC 17A and SC 17C will start with IEC 62271-1.
b) Standards of SC 17A will start with IEC 62271-100.
c) Standards of SC 17C will start with number IEC 62271-200.
d) Publications prepared by SC 17A and SC 17C will start with number IEC 62271-300.
