Foreword
The text of document 17B/1674/FDIS, future edition 3 of IEC 60947-4-1, prepared by SC 17B,
Low-voltage switchgear and controlgear, of IEC TC 17, Switchgear and controlgear, was submitted to the
IEC-CENELEC parallel vote and was approved by CENELEC as EN 60947-4-1 on 2010-04-01.
This standard is to be used in conjunction with EN 60947-1.
This European Standard supersedes EN 60947-4-1:2001 + A1:2002 + A2:2005.
This EN 60947-4-1 includes the following significant technical changes with respect to the
EN 60947-4-1:2001 + A1:2002 + A2:2005:
– deletion of the test at –5 °C and +20 °C for thermal overload relays that are not compensated for
ambient air temperature;
– addition of conditions of the tests according to Annex Q of EN 60947-1;
– EMC tests: clarification of acceptance criteria and alignment with EN 60947-1 for fast transient
severity level;
– Annex B, test for Icd: modification of the duration of the dielectric test voltage from 5 s to 60 s;
– Annex B, electrical durability: improvement of the statistical aspects;
– Annex H: clarification and introduction of new extended functions within electronic overload relays;
– Annex K, procedure to determine data for electromechanical contactors used in functional safety
applications: creation of this new annex.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent
rights.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
(dop) 2011-01-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2013-04-01
with the EN have to be withdrawn
This European Standard has been prepared under a mandate given to CENELEC by the European
Commission and the European Free Trade Association and covers essential requirements of
EC Directive 2004/108/EC. See Annex ZZ.
