(Main)Switches for household and similar fixed-electrical installations - Part 1: General requirements
Switches for household and similar fixed-electrical installations - Part 1: General requirements
IEC 60669-1:2017 applies to manually operated general purpose functional switches, for alternating current (AC) only with a rated voltage not exceeding 440 V with a rated current not exceeding 63 A, intended for household and similar fixed electrical installations, either indoors or outdoors. For switches provided with screwless terminals, the rated current is limited to 16 A. This fourth edition cancels and replaces the third edition published in 1998, Amendment 1:1999 and Amendment 2:2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) change of the scope for motor load switches;
b) deletion of some dated normative references;
c) changes to the definitions;
d) in Clause 5 the number of specimens to be used for the tests are clearly given in Table 1 (Corresponding Annex A of IEC 60669-1:1998 was therefore deleted);
e) in Clause 5 it was clarified on which switches the tests of Clause 19 shall be carried out;
f) requirements concerning 13 A switches have been included;
g) mandatory indication that a terminal is suitable for rigid conductor only;
h) requirements and test conditions for flexible conductors have been included in Clause 12;
i) requirements for pilot light units have been included;
j) new test for self-ballasted lamp loads in 19.3;
k) Table 20 has been completely redrawn to cover normal, mini and micro-gap switches and renumbered Table 21;
l) new informative Annex B including changes planned for the future in order to align IEC 60669-1 with the requirements of IEC 60998 (all parts), IEC 60999 (all parts) and IEC 60228;
m) new informative Annex C about the circuit development for 19.3;
n) new informative Annex D including additional requirements for insulation-piercing terminals;
o) new informative Annex E including additional requirements and tests for switches intended to be used at a temperature lower than -5 °C.
The contents of the corrigendum of January 2020 have been included in this copy.
Interrupteurs pour installations électriques fixes domestiques et analogues - Partie 1: Exigences générales
La présente partie de l'IEC 60669 s'applique aux interrupteurs fonctionnels pour courant alternatif seulement à commande manuelle pour usages courants, de tension assignée ne dépassant pas 440 V et de courant assigné ne dépassant pas 63 A, destinés aux installations électriques fixes domestiques et analogues soit intérieures soit extérieures.
Pour les interrupteurs équipés de bornes sans vis, le courant assigné est limité à 16 A.
Cette quatrième édition annule et remplace la troisième édition parue en 1998, l’Amendement 1:1999 et l’Amendement 2:2006. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) modification du domaine d’application concernant les interrupteurs pour charge moteur;
b) suppression de certaines références normatives datées;
c) modifications relatives aux définitions;
d) dans l’Article 5, le nombre d’échantillons à utiliser pour les essais est clairement indiqué dans le Tableau 1 (L’Annexe A correspondante de l’IEC 60669-1:1998 a donc été supprimée en conséquence);
e) dans l’Article 5, ajout de précisions concernant les interrupteurs sur lesquels les essais de l’Article 19 doivent être effectués;
f) ajout d’exigences relatives aux interrupteurs 13 A;
g) indication obligatoire signalant qu’une borne est adaptée pour un conducteur rigide uniquement;
h) ajout d’exigences et de conditions d’essai pour les conducteurs souples à l’Article 12;
i) ajout d’exigences relatives aux lampes indicatrices;
j) ajout d’un nouvel essai pour les charges par lampe à ballast intégré en 19.3;
k) Tableau 20 entièrement refait afin de couvrir les interrupteurs à distance normale d’ouverture des contacts, à faible distance d’ouverture des contacts et à microdistance d’ouverture des contacts et renuméroté Tableau 21;
l) ajout d’une nouvelle Annexe B informative comprenant les modifications prévues pour aligner l'IEC 60669-1 avec les exigences de l'IEC 60998 (toutes les parties), de l'IEC 60999 (toutes les parties) et de l'IEC 60228;
m) ajout d’une nouvelle Annexe C informative relative au développement du circuit pour 19.3;
n) ajout d’une nouvelle Annexe D informative comprenant des exigences complémentaires pour les bornes à perçage d'isolant;
o) ajout d’une nouvelle Annexe E informative comprenant des exigences et des essais supplémentaires pour les interrupteurs à utiliser à une température inférieure à −5 °C.
Le contenu du corrigendum de janvier 2020 a été pris en considération dans cet exemplaire.
