The requirements on contactors and motor-starters, particularly for semiconductor motor controllers, starters and soft-starters have been updated.

EN IEC 60947-4-2:2023 applies to semiconductor motor controllers, starters and soft-starters which can include a series mechanical switching device, intended to be connected to circuits the rated voltage of which does not exceed 1.000 V AC.

This fourth edition, which replaces the third edition published in 2011, is a technical revision.

It includes the following main changes:

  • scope exclusions,
  • editorial correction of notes and hanging paragraphs,
  • reference to IEC 62683-1,
  • safety aspects related to:
    • general aspects,
    • limited energy circuits,
    • electronic circuits,
    • mention of dedicated wiring accessories,
    • power consumption measurement,
    • alignment to IEC 60947-1:2020.
