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).
