This European Standard was approved by CENELEC on 1994-03-08,
amendment A11 was approved by CENELEC on 1998-04-01. 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, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy,

Foreword

Foreword to amendment A1

The text of the International Standard
IEC 61009-2-1:1990, which makes reference to and
finds application with IEC 61009-1:1990, was
submitted to the Unique Acceptance Procedure
(UAP) for acceptance as a European Standard
simultaneously with the UAP on prEN 61009-1.

This amendment was prepared by the Technical
Committee CENELEC TC 23E, Circuit breakers
and similar devices for household and similar
applications.

As the UAP on prEN 61009-1, for which common
modifications had been prepared by Technical
Committee CENELEC TC 23E, Circuit-breakers

and similar equipment for household and similar
use, did not obtain a sufficient number of positive
votes, neither document was accepted.
On the basis of the common modifications added
in the revised prEN 61009-1, no changes to
IEC 61009-2-1 were necessary and the document
was submitted to the formal vote.
The new draft was approved by CENELEC as
EN 61009-2-1 on 1994-03-08.
The following dates were fixed:
— latest date of publication
of an identical national
standard
— latest date of withdrawal
of conflicting national
standards

(dop) 1996-07-01
(dow) 2000-07-01

For products which have complied with the relevant
national standard before 2000-07-01, as shown by
the manufacturer or by a certification body, this
previous standard may continue to apply for
production until 2005-07-01.
Conformity of products with the requirements of
this standard ensures conformity with the essential
requirements of Directive 73/23/EEC (Low Voltage
Directive) and its amendment 93/68/EEC.
There are no special national conditions or

A-deviations to this European Standard other than
those listed in EN 61009-1:1994.

The text of the draft was submitted to the
Unique Acceptance Procedure and was approved
by CENELEC as amendment A11
to EN 61009-2-1:1994 on 1998-04-01
The following dates were fixed:
— latest date by which the
amendment has to be
implemented at national
level by publication of an
identical national standard
or by endorsement
(dop) 1998-11-01
— latest date by which the
national standards
conflicting with the
amendment have to be
withdrawn
