This European Standard was approved by CENELEC on 2014-05-01. 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 CEN-CENELEC
Management Centre 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 CEN-CENELEC Management Centre has the
same status as the official versions.
CENELEC members are the national electrotechnical committees of Austria, Belgium, Bulgaria, Croatia, Cyprus, the Czech Republic,
Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, the Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland,
Turkey and the United Kingdom.

Foreword
The text of document 17C/594/FDIS, future edition 2 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 approved by CENELEC as EN 62271-201:2014.

The following dates are fixed:
(dop) 2015-02-01
• latest date by which the document has to be
implemented at national level by
publication of an identical national
standard or by endorsement
• latest date by which the national (dow) 2017-05-01
standards conflicting with the
document have to be withdrawn
This document supersedes EN 62271-201:2006.

201:2006:
a) apart from updating with the second edition of EN 62271-200:2012, definitions,
classifications and testing procedures have been specified more precisely;
b) access to the solid-insulation enclosed switchgear and controlgear is now restricted to
authorized personnel only. This implies that “accessibility class B” (public access) has
been deleted throughout the document;
c) the term “protection category” has been introduced to replace the term “protection grade”
(PA, PB1 and PB2)
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CENELEC [and/or CEN] shall not be held responsible for identifying any or all such
patent rights.
Endorsement notice
