IEC 60269-2-1:1998

Low-voltage fuses - Part 2-1: Supplementary requirements for fuses for use by authorized persons (fuses mainly for industrial application) - Sections I to V: Examples of types of standardized fuses

This standard is divided into five sections, each dealing with a specific example of standardized fuse for use by authorized persons: Section I: Fuses with fuse-links with blade contacts. Section II: Fuses with fuse-links for bolted connections. Section III: Fuses with fuse-links having cylindrical contact caps. Section IV: Fuses with fuse-links with offset blade contacts. Section V: Fuses with fuse-links having "gD" and "gN" characteristics. NOTE - The following fuse systems are standardized systems in respect to their safety aspects. The National Committees may select from the examples of standardized fuses one or more systems for their own standards.

Fusibles basse tension - Partie 2-1: Règles supplémentaires pour les fusibles destinés à être utilisés par des personnes habilitées (fusibles pour usages essentiellement industriels) - Sections I à V: Exemples de fusibles normalisés

La présente norme est divisée en cinq sections traitant chacune d'un exemple spécifique de fusible normalisé destiné à être utilisé par des personnes habilitées: Section I: Fusibles avec éléments de remplacement à couteaux. Section II: Fusibles avec éléments de remplacement à platines. Section III: Fusibles avec éléments de remplacement à capsules cylindriques. Section IV: Fusibles avec éléments de remplacement à couteaux déportés. Section V: Fusibles dont les éléments de remplacement ont des caractéristiques "gD" et "gN". NOTE - Les systèmes de fusibles suivants sont normalisés en ce qui concerne les aspects de sécurité. Les Comités nationaux peuvent choisir, parmi les exemples de fusibles normalisés, un ou plusieurs systèmes pour leurs normes nationales.
