Anotation

IEC 60947-5-4:2002 applies to separable contacts used in the utilization area considered, such as switching elements for control circuits. This standard takes into consideration two rated voltage areas: a) above (and including) 10 V (typically 24 V) where contacts are used for switching loads with possible electrical erosion, such as programmable controller inputs; b) below 10 V (typically 5 V) with negligible electrical erosion, such as electronic circuits. This second edition cancels and replaces the first edition which was issued as a technical report in 1996. It now has the status of an International Standard. IEC 60947-5-4:2002 s’applique aux contacts separables utilises dans le domaine d’emploi considere, tels que les elements de commutation pour les circuits de commande. La presente norme prend en compte deux domaines de tensions assignees: a) tensions superieures (et egales) a 10 V (typiquement 24 V) pour lesquelles les contacts sont utilises pour commuter des charges avec possibilite d’erosion electrique, par exemple les entrees d’automates programmables; b) les tensions inferieures a 10 V (typiquement 5 V) pour lesquelles l’erosion electrique des contacts est negligeable, par exemple dans les circuits electroniques. Cette deuxieme edition annule et remplace la premiere edition parue comme rapport technique en 1996. Elle a desormais le statut de norme internationale.
