Annotation of standard text IEC 61095-ed.3.0 :
IEC 61095:2023 applies to electromechanical air break contactors for household and similar purposes provided with main contacts intended to be connected to circuits the rated voltage of which does not exceed 440 V AC (between phases) with rated operational currents less than or equal to 63 A for utilization category AC-7a, and 32 A for utilization categories AC-7b, AC-7c and AC-7d (expressed in rated power), and rated conditional short-circuit current less than or equal to 6 kA. This third edition cancels and replaces the second edition published in 2009. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) addition of requirements for screwless terminals; b) addition of requirements for the switching of LED lamps. Contactors for domestic and similar applications can be used for controlling lighting loads which is increasingly using LED lamp technology. A specific category for contactors is created: AC-7d. Requirements and tests are added to cover this market development, mainly for making and breaking and conventional operational performance; c) addition of requirements for contactors with electronically controlled electromagnet. Household contactors with electronically controlled electromagnet are available for years on the market. To fully cover such device, requirements and tests are added, dealing mainly with operating limits, behaviour in abnormal conditions, breakdown of components, EMC tests, etc. d) embedded software. More and more contactors are incorporating electronic circuits with embedded software. A reference is provided to guide the design of the software. LIEC 61095:2023 sapplique aux contacteurs electromecaniques a air pour usages domestiques et analogues dont les contacts principaux sont destines a etre relies a des circuits dont la tension assignee ne depasse pas 440 V en courant alternatif (entre phases) et dont les courants assignes demploi sont inferieurs ou egaux a 63 A pour la categorie demploi AC-7a et a 32 A pour les categories demploi AC-7b, AC-7c et AC-7d (exprimes en puissance assignee), et le courant assigne de court-circuit conditionnel est inferieur ou egal a 6 kA. Cette troisieme edition annule et remplace la deuxieme edition parue en 2009. Cette edition constitue une revision technique. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: a) ajout des exigences relatives aux bornes sans vis; b) ajout des exigences relatives a la commande des lampes a LED. Les contacteurs pour applications domestiques et analogues peuvent etre utilises pour commander les charges declairage, qui utilisent de plus en plus la technologie de lampe a LED. Creation dune categorie specifique pour les contacteurs: AC-7d. Des exigences et des essais ont ete ajoutes pour couvrir cette evolution du marche, notamment en ce qui concerne la fermeture et la coupure et le fonctionnement conventionnel en service; c) ajout des exigences relatives aux contacteurs qui comportent un electroaimant commande electroniquement. Les contacteurs domestiques qui comportent un electroaimant commande electroniquement sont disponibles sur le marche depuis des annees. Pour couvrir pleinement les appareils de ce types, des exigences et des essais ont ete ajoutes, qui traitent notamment des limites de fonctionnement, du comportement en conditions anormales, du claquage des composants, des essais CEM, etc. d) concernant les logiciels integres, de plus en plus de contacteurs contiennent des circuits electroniques avec un logiciel integre. Une reference est fournie a titre de guide pour la conception des logiciels.
