This European Standard was approved by CENELEC on 2011-11-28. 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, 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/523/FDIS, future edition 2 of IEC 62271-200, 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 62271-200:2012.

The following dates are fixed:
(dop) 2012-08-28
• latest date by which the document has
to be implemented at national level by
publication of an identical national
standard or by endorsement
(dow) 2014-11-28
• latest date by which the national
standards conflicting with the
document have to be withdrawn
This document supersedes EN 62271-200:2004.
EN 62271-200:2004. As maintenance result, EN 62271-200:2012 introduces the following significant
changes:
 definitions, classifications and testing procedures are specified more precisely;
 categories LSC2A and LSC2B have been clarified and LSC2 has been assigned a separate definition;
 specific ratings related to fault level to earth (4.5 to 4.7) are introduced;
 solid insulated high-voltage parts are no longer considered as compartments on their own;
 an optional rating "cable test voltage" and the associated requirements and type tests are introduced;
 for testing the internal arc classification, when assigned by the manufacturer, more specific guidance is
provided regarding the test arrangement, room simulation and arc initiation;
 a single phase to earth ignition is also recognised for internal arc testing;
 the Annexes A and B are renumbered Annexes AA and BB.
The level of severity of internal arc testing is maintained without changes.
This European Standard should be read in conjunction with EN 62271-1:2008, 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 62271-1. Amendments to
these clauses and subclauses are given under the same numbering, whilst additional subclauses, are
numbered from 101.
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.

A-deviations
A-deviation: National deviation due to regulations, the alteration of which is for the time being outside the
competence of the CENELEC member.
This European Standard does not fall under any Directive.
In the relevant CEN/CENELEC countries these A-deviations are valid instead of the provisions of the
European Standard until they have been removed.
Clause Deviation
1 Italy (Italian pressure vessel code for electrical switchgear DM 1 December 1980 and DM
10 September 1981 published in Gazzetta Ufficiale n° 285 dated 16.10.1981)
For metal-enclosed switchgear and controlgear containing gas-filled compartments, the
design pressure is limited to a maximum of 0,5 bar (gauge) and the volume is limited to a
maximum of 2 m . Gas filled compartments having a design pressure exceeding 0,5 bar
(gauge) or a volume exceeding 2 m shall be designed according to the Italian pressure
vessel code for electrical switchgear.
