IEC 60947-4-1:2018 is applicable to the following equipment:
  • electromechanical contactors and starters including motor protective switching device (MPSD);
  • actuators of contactor relays;
  • contacts dedicated exclusively to the coil circuit of this contactor or this contactor relay;
  • dedicated accessories (e.g. dedicated wiring, dedicated latch accessory); intended to be connected to distribution circuits, motors circuits and other load circuits, the rated voltage of which does not exceed 1 000 V AC or 1 500 V DC. This fourth edition cancels and replaces the third edition published in 2009 and its Amendment 1:2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
  • Scope structure and exclusions
  • Editorial correction of notes and hanging paragraphs
  • Reference to IEC 62683-1
  • Motor protective switching device (MPSD) with its requirements
  • Safety aspects related to:
  • General aspects;
  • Limited energy circuits;
  • Electronic circuits;
  • Assessment procedure for electromechanical overload protection used in safety -applications (new Annex L)
  • Introduction of provisions covering the impact of higher locked rotor current to achieve high efficiency class
  • Mention of dedicated wiring accessories
  • Pickup power measurement
  • Alignment to IEC 60947-1:2007, IEC 60947-1:2007/AMD1:2010, and IEC 60947-1:2007/AMD2:2014
  • Direct current requirements for covering photovoltaic application (new Annex M)
  • Load monitoring indicators (new Annex O)
  • Short-circuit breaking tests of MPSD (new Annex P)
  • Co-ordination under short-circuit conditions between a MPSD and another short-circuit protective device associated in the same circuit (new Annex Q).
