Annotation of standard text IEC 60947-6-2-ed.3.0 :
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 corrigenda of December 2021 and June 2023 have been included in this copy. IEC 60947-6-2:2020 s’applique aux appareils (ou au materiel) de connexion de commande et de protection (ACP), dont les contacts principaux sont destines a etre relies a des circuits dont la tension assignee n’est pas superieure a 1 000 V en courant alternatif ou 1 500 V en courant continu. Il traite des appareils de connexion de commande de protection (ACP): qui offrent des fonctions de protection et de commande pour les circuits et les moteurs; dont la fonction de commande est manouvree exclusivement autrement que manuellement; qui permettent la continuite de service apres des conditions de surintensite; et qui peuvent avoir d’autres fonctions, telles que le sectionnement ou la communication. Cette troisieme edition annule et remplace la deuxieme edition parue en 2002 et l’Amendement 1:2007. Cette edition constitue une revision technique. La presente edition inclut les modifications techniques majeures suivantes par rapport a l’edition precedente: modifications redactionnelles conformement a la Partie 2 des Directives ISO/IEC; alignements sur l’IEC 60947-1:2020: marquages ("s", "sol", "r" ou "f"); exigences relatives a la construction, dont exigences relatives aux materiaux; exigences pour les bornes sans vis; methode de mesurage de l’impedance de pole; exigence et essais pour la compatibilite electromagnetique (CEM); procedure pour determiner les donnees pour les ACP electromecaniques utilises dans les applications de securite fonctionnelle; harmonisation avec l’IEC 60947-2:2016: essais de fonctionnement des relais et declencheurs a bobine en derivation a minimum de tension; ACP pour les schemas de mise a la terre de type IT (Annexe G); coordination avec les autres dispositifs de protection contre les courts-circuits; alignements sur l’IEC 60947-4-1:2018: essai au courant conditionnel de court-circuit assigne Iq des appareils de connexion proteges; harmonisation des essais de court-circuit avec l’Amerique du Nord; donnees de fiabilite pour les applications de securite fonctionnelle (nouvelle Annexe K); aspects de securite relatifs aux circuits electroniques et a l’impedance de protection (nouvelle Annexe N); introduction de dispositions traitant de l’impact des moteurs utilisant des valeurs etendues du courant de rotor bloque pour atteindre une classe de rendement elevee; mention des accessoires de cablage dedies; definitions et methode de mesurage de la consommation d’energie du circuit de commande pendant les operations de maintien et d’appel; indicateurs de surveillance de la charge (nouvelle Annexe M). Le contenu du corrigendum de decembre 2021 et juin 2023 a ete pris en consideration dans cet exemplaire.
