This European Standard was approved by CENELEC on 2000-11-01. 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, Czech Republic,
Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway,
Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword
The text of document 23E/430/FDIS, future edition 3 of IEC 60934, prepared by SC 23E,
Circuit-breakers and similar equipment for household use, of IEC TC 23, Electrical accessories, was
submitted to the IEC-CENELEC parallel vote and was approved by CENELEC as EN 60934 on
2000-11-01.
This European Standard supersedes EN 60934:1994 + A1:1994 + A2:1997 + A11:1998.
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) 2001-08-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2003-11-01
Annexes designated "normative" are part of the body of the standard.
Annexes designated "informative" are given for information only.
In this standard, annexes A, B, C, D, E, G, H, J, K and ZA are normative and annex F is informative.
Annex ZA has been added by CENELEC.
In this standard the following print types are used:
- requirements: in roman type;
- test specifications: in italic type;
- notes: in smaller roman type.
