Switches for household and similar fixed electrical installations - Part 2-1: Particular requirements - Electronic control devices

IEC 60669-2-1:2021 applies to electronic control devices, a general term to cover electronic switches, home and building electronic systems (HBES) / building automation and control systems (BACS) switches and electronic extension units.
It applies to electronic switches and to HBES/BACS switches, for alternating current (AC) only with a rated switching voltage not exceeding 250 V and a rated current not exceeding 16 A, intended for household and similar fixed electrical installations, either indoors or outdoors.
It also applies to electronic extension units with a rated supply voltage not exceeding 250 V AC and 120 V DC, such as sensors and push buttons.
This document also applies to electronic remote control switches (RCS) and electronic time delay switches (TDS). Particular requirements are given in Annex FF.
This fifth edition cancels and replaces the fourth edition published in 2002, Amendment 1:2008 and Amendment 2:2015. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) incorporation of the requirements for HBES switches, previously included in IEC 60669-2-5;
b) modification of 19.106, test and requirements for switches for LEDs;
c) general indication to cover electronic control devices;
d) test for looping through.
The contents of the corrigendum of May 2024 have been included in this copy.

Interrupteurs pour installations électriques fixes domestiques et analogues - Partie 2-1: Exigences particulières - Dispositifs de commande électronique

l’IEC 60669-2-1:2021 s’applique aux dispositifs de commande électronique, c’est-à-dire un terme général qui englobe les interrupteurs électroniques, les interrupteurs des systèmes électroniques pour les foyers domestiques et les bâtiments (HBES) / systèmes de gestion technique des bâtiments (SGTB) et les éléments électroniques périphériques.
Elle s’applique aux interrupteurs électroniques et aux interrupteurs HBES/SGTB, pour courant alternatif seulement, de tension de coupure assignée ne dépassant pas 250 V et de courant assigné ne dépassant pas 16 A, prévus pour des installations électriques fixes domestiques et analogues, intérieures ou extérieures.
Elle s’applique également aux éléments électroniques périphériques dont la tension d’alimentation assignée ne dépasse pas 250 V en courant alternatif et 120 V en courant continu, comme les capteurs et les boutons-poussoirs.
Le présent document s’applique également aux télérupteurs électroniques et aux minuteries électroniques. Des exigences particulières sont données dans l’Annexe FF.
Cette cinquième édition annule et remplace la quatrième édition parue en 2002,
l'Amendement 1:2008 et l'Amendement 2:2015. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) intégration des exigences relatives aux interrupteurs HBES, précédemment incluses dans la norme IEC 60669-2-5;
b) modification de 19.106, essais et exigences pour les interrupteurs pour LED;
c) indications générales pour couvrir les dispositifs de commande électronique;
d) essai de boucle.
Le contenu du corrigendum de mai 2024 a été pris en considération dans cet exemplaire.
