Scope

IEC 60947-6-2:2020 This document applies to control and protective switching devices (or equipment) (CPS), the main contacts of which are intended to be connected to circuits of rated voltage not exceeding 1 000 V AC or 1 500 V DC.
It covers control and protective switching device (CPS):
which provides protective and control functions for circuits and motors;
where its control function is operated exclusively otherwise than by hand;
which provides continuity of service after over-current conditions; and
which can have additional functions, such as isolation or communication.
This third edition cancels and replaces the second edition published in 2002 and its Amendment 1:2007. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
editorial changes according to ISO/IEC directives Part 2,
alignments with IEC 60947-1:2020:
markings ("s", "sol", "r" or "f");
constructional requirements including material requirements;
requirements for screwless terminals;
measurement method of the pole impedance;
EMC requirement and testing;
procedure to determine data for electromechanical CPS’s used in functional safety applications;

harmonisation with IEC 60947-2:2016:
operation tests of under-voltage relays and shunt releases;
CPS for IT systems (Annex G);
coordination with other short-circuit protective devices;

alignments with IEC 60947-4-1:2018:
test at the rated conditional short-circuit current Iq of protected switching devices;
short-circuit tests harmonisation with North America;
reliability data for functional safety applications (new Annex K);
safety aspects related to electronic circuits and protective impedance (new Annex N);
introduction of provisions covering the impact of higher locked rotor current to achieve high efficiency class;
mention of dedicated wiring accessories;
definitions and measurement method of the power consumption of the control circuit during holding and pick-up operations;
load monitoring indicators (new Annex M).

The contents of the corrigendum of December 2021 have been included in this copy.
