Low-voltage switchgear and controlgear - Part 4-1: Contactors and motor-starters - Electromechanical...
IEC 60947-4-1:2009 applies to the types of equipment whose main contacts 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. Starters and/or contactors dealt with in this standard are not normally designed to interrupt short-circuit currents. Therefore, suitable short-circuit protection forms part of the installation but not necessarily…
