    Abstract - (Show below) - (Hide below)

    IEC 60947-2:2016 is available as IEC 60947-2:2016
    RLV which contains the International Standard and its Redline
    version, showing all changes of the technical content compared to
    the previous edition.


    IEC 60947-2:2016 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. This fifth edition cancels and replaces the fourth edition published in 2006, Amendment 1:2009 and Amendment 2:2013. This edition constitutes a technical revision. This edition includes the following significant additions with respect to the previous edition:

    - tests for verification of selectivity in Annex A (see A.5.3);

    - critical load current tests for d.c. circuit-breakers (see 8.3.9);

    - new Annex P for circuit-breakers for use in photovoltaic applications;

    - new Annex R for residual-current circuit-breakers with automatic reclosing functions.
