IEC 60947-4-1:2018 is available as IEC 60947-4-1:2018 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.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).
