This European Standard was approved by CENELEC on 2004-02-01. 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.

CENELEC members are the national electrotechnical committees of Austria, Belgium, Cyprus, Czech
Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia,
Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden,

Foreword
The text of document 17C/311/FDIS, future edition 1 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 was approved by CENELEC as EN 62271-200 on
2004-02-01.
This European Standard supersedes EN 60298:1996 + A11:1999.
Significant technical changes with respect to EN 60298:1996 are as follows:
This revised document has been basically changed to be updated to today's use of high-voltage
switchgear and controlgear up to 52 kV. The main changes are: new definitions and classification of
equipment, introduction of internal arc classes (IAC) and its testing.
This standard is to be read in conjunction with EN 60694:1996. Clause numbering follows the clause
numbering of that standard. Additional subclauses, as they relate to a particular clause or subclause
from EN 60694, are numbered 101, 102, etc.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2004-11-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2007-02-01
Annexes ZA and ZB have been added by CENELEC.

Endorsement notice
The text of the International Standard IEC 62271-200:2003 was approved by CENELEC as a
European Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
IEC 60137 NOTE Harmonized as EN 60137:1996 (not modified).

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 of the EC.
In the relevant 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.
