f) addition of requirements for screwless-type clamping units;
g) udpate of existing Tables 4 and 5;
h) addition of new Tables 6, 7, 8 and 9;
i) addition of a new Figure 10 ;
j) addition of a new Annex N.
This publication is to be read in conjunction with IEC 60947-1:2007.
The contents of the corrigendum of July 2016 and the corrigendum of April 2020 have been included in this copy.
Appareillage à basse tension - Partie 5-1: Appareils et éléments de commutation pour circuits de commande - Appareils électromécaniques pour circuits de commande
L'IEC 60947-5-1:2016 est applicable aux appareils pour circuits de commande et aux éléments de commutation destinés à la commande, la signalisation, le verrouillage, etc., de l'appareillage. Elle est applicable aux appareils pour circuits de commande dont la tension assignée ne dépasse pas 1 000 V en courant alternatif (à une fréquence ne dépassant pas 1 000 Hz) ou 600 V en courant continu. Cette quatrième édition annule et remplace la troisième édition parue en 2003 et l'Amendement 1:2009. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) mise à jour des références normatives;
b) mise à jour et restructuration des paragraphes du 7.1;
c) addition des exigences et de l'essai relatif aux matériaux;
d) mise à jour des exigences CEM;
e) clarification des exigences et mise à jour du 8.2;
f) addition des exigences pour les organes de serrage sans vis;
g) mise à jour des Tableaux 4 et 5 existants;
h) addition des nouveaux Tableaux 6,7, 8 et 9;
i) addition de la nouvelle Figure 10;
j) addition de la nouvelle Annexe N.
Cette publication doit être lue conjointement avec la IEC 60947-1:2007.
