Foreword The text of document 17B/1455/FDIS, future edition 4 of IEC 60947
11、-2, 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 60947-2 on 2006-07-01. This European Standard supersedes EN 60947-2:2003. The main changes introduced in EN 60947
12、-2:2006 are an amendment to the verification of dielectric properties, the improvement of EMC clauses in Annexes B, F, J and M, and the addition of a new Annex O regarding instantaneous trip circuit-breakers. The following dates were fixed: latest date by which the EN has to be implemented at nation
13、al level by publication of an identical national standard or by endorsement (dop) 2007-04-01 latest date by which the national standards conflicting with the EN have to be withdrawn (dow) 2009-07-01 This European Standard has been prepared under a mandate given to CENELEC by the European Commission
14、and the European Free Trade Association and covers essential requirements of EC Directive EMC (89/336/CEE). See Annex ZZ. Annexes ZA and ZZ have been added by CENELEC. _ Endorsement notice The text of the International Standard IEC 60947-2:2006 was approved by CENELEC as a European Standard without
