Installation couplers intended for permanent connection in fixed installations

IEC 61535:2023 is available as IEC 61535:2023 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 61535:2023 applies to two-wire, up to five-wire installation couplers, with or without earthing contact, if provided, with a rated voltage up to and including 500 V AC or 500 V DC and a rated connecting capacity up to and including 10 mm2 and a rated current not exceeding 32 A for permanent connection in electrical installations. Installation couplers with additional contacts for voltages other than mains voltages are outside the scope of this document. This third edition cancels and replaces the second edition published in 2019. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) inclusion of a definition for "live part" based on IEC 61140; b) additional optional cross medial documentation, e.g. marking with QR-Code; c) corrections on the consistent use of the expressions "earth", "earthing contact", "earthing circuit" and "protective earth(ing)" throughout the document; d) addition of missing compliance provisions to 13.3; e) update of Figure D.1 of Annex D; f) inclusion of new Annex F for cold climate requirements.

Coupleurs d'installation pour connexions permanentes dans les installations fixes

IEC 61535:2023 est disponible sous forme de IEC 61535:2023 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 61535:2023 s'applique aux coupleurs d'installation qui comportent deux à cinq conducteurs, avec ou sans contact de terre (le cas échéant), de tension continue ou alternative assignée jusqu'à 500 V inclus et de capacité assignée de connexion jusqu'à 10 mm2 inclus, avec un courant assigné qui ne dépasse pas 32 A, pour connexion permanente dans les installations électriques. Les coupleurs d'installation avec des contacts supplémentaires pour des tensions autres que la tension d'alimentation du réseau ne relèvent pas du domaine d'application du présent document. Cette troisième édition annule et remplace la deuxième édition parue en 2019. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) inclusion d'une définition issue de l'IEC 61140 pour "partie active"; b) documentation facultative supplémentaire disponible sur plusieurs supports, par exemple marquage avec QR code; c) corrections relatives à l'utilisation cohérente des expressions "terre", "contact de terre", "circuit de terre" et "(mise à la) terre de protection" dans l'ensemble du document; d) ajout de dispositions de conformité manquantes au 13.3; e) mise à jour de la Figure D.1 de l'Annexe D; f) ajout d'une nouvelle Annexe F pour les exigences relatives aux climats froids.
