Foreword
The text of document 94/243/CDV, future edition 1 of IEC 62246-2, prepared by IEC TC 94, All-or-nothing
electrical relays, was submitted to the IEC-CENELEC Parallel Unique Acceptance Procedure and was
approved by CENELEC as EN 62246-2 on 2007-12-01.
This European Standard is to be read in conjunction with EN 62246-1:2002.
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) 2008-09-01
– latest date by which the national standards conflicting
(dow) 2010-12-01
with the EN have to be withdrawn
Annex ZA has been added by CENELEC.
