Annotation of standard text IEC 60255-27-ed.3.0 :
IEC 60255-27:2023 specifies the product safety requirements for measuring relays and protection equipment having a rated AC voltage up to 1 000 V, or a rated DC voltage up to 1 500 V. This document specifies essential safety requirements to minimize the risk of fire and hazards caused by electric shock or injury to the user and property. This document specifies only product safety requirements; functional performance of the equipment is not covered. This document covers all the ways in which the equipment can be mounted and used in cabinets, racks and panels. This document also applies to auxiliary devices such as shunts, series resistors, transformers, auxiliary control panels, display devices, etc., that are used in conjunction with measuring relays and protection equipment and are tested together. LIEC 60255-27:2023 specifie les exigences de securite des produits pour les relais de mesure et les dispositifs de protection avec une tension assignee en courant alternatif inferieure ou egale a 1 000 V ou avec une tension assignee en courant continu inferieure ou egale a 1 500 V. Le present document specifie les exigences de securite fondamentales pour reduire le plus possible les risques dincendie et de dangers causes par un choc electrique ou les risques de blessure de lutilisateur et de degradation materielle. Le present document specifie uniquement les exigences de securite des produits; les performances fonctionnelles du materiel ne sont pas couvertes. En revanche, le present document couvre tous les modes qui peuvent etre utilises pour le montage et lutilisation du dispositif dans des baies, des racks ou des panneaux. Le present document sapplique aussi aux dispositifs auxiliaires comme les shunts, resistances serie, transformateurs, panneaux de commande auxiliaires, dispositifs daffichage, etc., qui sont utilises conjointement avec les relais de mesure et les dispositifs de protection et sont soumis a lessai ensemble.
