This European Standard was approved by CENELEC on 2006-10-01. CENELEC members are bound to comply
with the CEN/CENELEC Internal Regulations which stipulate the conditions for giving this European Standard
the status of a national standard without any alteration.

Up-to-date lists and bibliographical references concerning such national standards may be obtained on
application to the Central Secretariat or to any CENELEC member.

This European Standard exists in three official versions (English, French, German). A version in any other
language made by translation under the responsibility of a CENELEC member into its own language and notified
to the Central Secretariat has the same status as the official versions.

Foreword
The text of document 17C/374/FDIS, future edition 1 of IEC 62271-201, prepared by SC 17C,
High-voltage switchgear and controlgear assemblies, of IEC TC 17, Switchgear and controlgear, was
submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 62271-201 on
2006-10-01.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2007-07-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2009-10-01
with the EN have to be withdrawn
This standard should be read in conjunction with EN 60694:1996 + A1:2000 + A2:2001, 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 EN 60694. Amendments to
these clauses and subclauses are given under the same numbering, whilst additional subclauses are
numbered from 101.
Annexes ZA and ZB have been added by CENELEC.
The contents of the corrigendum of November 2006 have been included in this copy.

Endorsement notice
The text of the International Standard IEC 62271-201:2006 was approved by CENELEC as a European
Standard without any modification.
In the official version, for Bibliography, the following note has to be added for the standard indicated:
