IEC 61535:2023 is available as IEC 61535:2023 RLV<\/span> 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.<\/p>\n
