IEC 60077-5:2019 is available as IEC 60077-5:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60077-5:2019 give additional or amended rules for high voltage (HV) fuses as a supplement to those given by IEC 60077-2. The high voltage fuses concerned are those connected into power and/or auxiliary circuits. The nominal voltage of these circuits lies between 600 V DC and 3 000 V DC, according to IEC 60850. These fuses can also be used in auxiliary AC circuits up to a nominal voltage of 1 500 V. This document together with IEC 60077-2 states specifically: a) the characteristics of the fuses; b) the service conditions with which the fuses comply with reference to: - operation and behaviour in normal service; - operation and behaviour in case of short circuit; - dielectric properties. c) the tests intended for confirming the compliance of the fuse with the characteristics under the service conditions and the methods adopted for these tests; d) the information marked on, or given with, the fuse. This second edition cancels and replaces the first edition, issued in 2003. This edition includes the following main technical changes with regard to the previous edition: a) test method of test duty III for verification of breaking capacity is reviewed.

IEC 60077-5:2019 est disponible sous forme de IEC 60077-5:2019 RLV qui contient la Norme internationale et sa version Redline, illustrant les modifications du contenu technique depuis l'édition précédente.L'IEC 60077-5:2019 fournir des règles complémentaires ou amendées pour les fusibles à haute tension, en plus de celles données dans l'IEC 60077-2. Les fusibles à haute tension concernés sont connectés dans les circuits de puissance et/ou auxiliaires. La tension nominale de ces circuits est située entre 600 V CC et 3 000 V CC, conformément à l'IEC 60850. Ces fusibles peuvent également être utilisés dans des circuits auxiliaires à courant alternatif jusqu'à une tension nominale de 1 500 V. En complément de l'IEC 60077-2, le présent document précise particulièrement: a) les caractéristiques des fusibles; b) les conditions de service que les fusibles supportent du point de vue: - du fonctionnement et du comportement en service normal; - du fonctionnement et du comportement en cas de court-circuit; - des propriétés diélectriques. c) les essais destinés à vérifier la conformité du fusible avec les caractéristiques dans les conditions de service ainsi que les méthodes à adopter pour ces essais; d) les informations données avec ou marquées sur le fusible. Cette deuxième édition annule et remplace la première édition, parue en 2003. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) révision de la méthode d'essai des conditions d'essai III pour la vérification du pouvoir de coupure.
