Description
IEC 60947-2:2006+A1:2009 applies to circuit-breakers, the main contacts of which are intended to be connected to circuits, the rated voltage of which does not exceed 1 000 V a.c. or 1 500 V d.c.; it also contains additional requirements for integrally fused circuit-breakers. The main changes introduced in this new edition 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 technical content is therefore identical to the base edition and its amendment and has been prepared for user convenience. It bears the edition number 4.1. The provisions of the general rules dealt with in IEC 60947-1 are applicable to this standard, where specifically called for.
This consolidated version consists of the fourth edition (2006)
and its amendment 1 (2009). Therefore, no need to order amendment in
addition to this publication.
