Low-voltage switchgear and controlgear - Part 2: Circuit-breakers (IEC 60947-2:2006 + A1:2009 + A2:2013); German version EN 60947-2:2006 + A1:2009 + A2:2013
Niederspannungsschaltgeräte - Teil 2: Leistungsschalter (IEC 60947-2:2006 + A1:2009 + A2:2013); Deutsche Fassung EN 60947-2:2006 + A1:2009 + A2:2013
Overview
This standard 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. It applies whatever the rated currents, the method of construction or the proposed applications of the circuit-breakers may be. Amendment 2 of DIN EN 60947-2 essentially contains revised requirements and tests for selectivity. The tests for the verification of selectivity between circuit-breakers and test results to be achieved have been supplemented, amongst others. The responsible committee is DKE/K 431 "Niederspannungsschaltgeräte und -kombinationen" ("Low-voltage switchgear and controlgear assemblies") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
