This European Standard was approved by CENELEC on 2008-05-01. 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 Central Secretariat or to any CENELEC member.

This European Standard exists in two official versions (English and 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, Bulgaria, 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 and the United Kingdom.

Foreword
The text of document 94/267/FDIS, future edition 3 of IEC 61810-1, prepared by IEC TC 94,
All-or-nothing electrical relays, was submitted to the IEC-CENELEC parallel vote and was approved by
CENELEC as EN 61810-1 on 2008-05-01.
This European Standard supersedes EN 61810-1:2004.
The relevant modifications compared to EN 61810-1:2004 are:
– update of references;
– renumbering of clauses to bring them into a more logical order;
– inclusion of contact load categories (same as in EN 61810-2 and EN 61810-7);
– clarifications concerning electrical endurance (Clause 11);
– inclusion of provisions for insulation coordination in accordance with the basic safety standards
EN 60664-3, EN 60664-4 and EN 60664-5 (Clause 13);
– renumbering of all annexes in the order they are referenced in the body of the standard;
– inclusion of new Annex C (normative) for the test set-up, and new Annex D (informative) for special
loads (based upon similar annexes in EN 61810-2 and EN 61810-7);
– improvement of Annex B covering inductive contact loads.
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) 2009-02-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2011-05-01
Annex ZA has been added by CENELEC.
__________
Endorsement notice

Standard without any modification.
In the official version, for Bibliography, the following notes have to be added for the standards indicated:
