SIST HD 60269-2:2013/A1:2023

Low-voltage fuses - Part 2: Supplementary requirements for fuses for use by authorized persons (fuses mainly for industrial application) - Examples of standardized systems of fuses A to K (IEC 60269-2:2013/A1:2016)

IEC 60269-2:2013 provides supplementary requirements for fuses for use by authorized persons and are generally designed to be used in installations where the fuse-links are accessible to, and may be replaced by, authorized persons only. Fuses for use by authorized persons according to the following fuse systems also comply with the requirements of the corresponding subclauses of IEC 60269-1, unless otherwise defined in this standard. This standard is divided into fuse systems, each dealing with a specific example of standardized fuses for use by authorized persons:  - Fuse system A: Fuses with fuse-links with blade contacts (NH fuse system),  - Fuse system B: Fuses with striker fuse-links with blade contacts (NH fuse system),  - Fuse system C: Fuse-rails (NH fuse system),  - Fuse system D: Fuse-bases for busbar mounting (NH fuse system),  - Fuse system E: Fuses with fuse-links for bolted connections (BS bolted fuse system),  - Fuse system F: Fuses with fuse-links having cylindrical contact caps (NF cylindrical fuse system),  - Fuse system G: Fuses with fuse-links with offset blade contacts (BS clip-in fuse system),  - Fuse system H: Fuses with fuse-links having 'gD' and 'gN' characteristic (class J and class time delay and non time delay fuse types),  - Fuse system I: gU fuse-links with wedge tightening contacts,  - Fuse system J: Fuses with fuse-links having 'gD class CC' and 'gN class CC' characteristics (class CC time delay and non-time delay fuse types),  - Fuse system K: gK fuse-links with blade for bolted connections - High fuse-link ratings from 1 250 A up to 4 800 A (master fuse-links). This fifth edition of IEC 60269-2 cancels and replaces the fourth edition published in 2010. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:  1. fuse systems A and B: modified values for the power dissipation of NH aM fuse-links;  2. fuse systems A and B: introduction of dimension r for NH fuse-links;  3. addition of new fuse system K: gK fuse-links with contacts for bolted connections.   Key Words: fuse systems A to K,  requirements for fuses

La CEI 60269-2:2013 fournit des exigences supplémentaires pour les fusibles destinés à être utilisés par des personnes habilitées et sont généralement conçus pour usage dans des installations où les éléments de remplacement ne sont accessibles qu'à des personnes habilitées, et ne peuvent être remplacés que par elles. Sauf indication contraire dans cette norme, les fusibles destinés à être utilisés par des personnes habilitées et correspondant aux systèmes de fusibles suivant satisfont également aux exigences des paragraphes correspondants de la CEI 60269-1. La présente norme est divisée en systèmes de fusibles traitant chacun d'un exemple spécifique de fusibles normalisés destinés à être utilisés par des personnes habilitées:  - Système de fusibles A: Fusibles avec éléments de remplacement à couteaux (système de fusibles NH),  - Système de fusibles B: Fusibles avec éléments de remplacement à couteaux avec percuteur (système de fusibles NH),  - Système de fusibles C: Réglettes à fusible (système de fusibles NH),  - Système de fusibles D: Socles pour montage sur jeu de barres (système de fusibles NH),  - Système de fusibles E: Fusibles avec éléments de remplacement à platines (système de fusibles à platines BS),  - Système de fusibles F: Fusibles avec éléments de remplacement à capsules cylindriques (système de fusibles cylindriques NF),  - Système de fusibles G: Fusibles avec éléments de remplacement à couteaux déportés (système de fusibles à pattes d'attache BS),  - Système de fusibles H: Fusibles dont les éléments de remplacement ont des caractéristiques 'gD' et 'gN' (types de fusibles temporisés ou non temporisés de classe J et de classe L),  - Système de fusibles I: Eléments de remplacement gU à contacts de serrage à encoche,  - Système de fusibles J: Fusibles dont les éléments de remplacement ont des caractéristiques 'gD de classe CC' et 'gN de classe CC' (types de fusibles temporisés et non temporisés de classe CC),  - Système de fusibles K: Eléments de remplacement gK à couteaux  pour raccordement boulonnés - Eléments de remplacement de courants assignés élevés de 1250 A à 4 800 A (master fusibles). Cette cinquième édition de la CEI 60269-2 annule et remplace la quatrième édition parue en 2010. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:  1. systèmes de fusibles A et B: modification des valeurs de puissance dissipée des éléments de remplacement des NH aM;  2. systèmes de fusibles A et B: introduction des dimensions r des éléments de remplacement NH;  3. ajout d'un nouveau système de fusibles K: éléments de remplacement gK à couteaux pour raccordement boulonné.   Mots clés: systèmes de fusibles normalisés A à K, exigences supplémentaires pour les fusibles

Overview

SIST HD 60269-2:2013/A1:2023 specifies supplementary requirements for low-voltage fuses intended for use by authorized personnel, particularly in industrial environments. This standard provides detailed guidelines and examples for standardized fuse systems A to K, ensuring consistent safety and performance across various types of industrial fuses. It is harmonized with IEC 60269-2:2013/A1:2016, representing the latest international best practices for low-voltage fuses in settings where only trained, authorized individuals are permitted to access and replace fuse-links. The requirements work in conjunction with the general provisions of IEC 60269-1, except where specifically modified in this document.

Key Topics

• Standardized Fuse Systems A-K: The standard classifies and details various fuse systems designed for industrial applications, such as:
  • NH fuse systems with blade contacts (A, B)
  • NH striker fuse-links (B)
  • Fuse-rails and bases for busbar mounting (C, D)
  • BS bolted and clip-in fuse systems (E, G)
  • NF cylindrical fuse systems (F)
  • Specialized fuse-links for high current or specific performance characteristics (H, I, J, K)
• Supplementary Requirements: Additional technical and safety requirements for each fuse system, including dimensions, markings, performance metrics, and allowed installation configurations.
• Accessibility and Safety: Specific focus on ensuring that only authorized personnel have access to these fuses, enhancing workplace safety and complying with industrial standards for electrical installations.
• Technical Revisions: Includes updated requirements for fuse-link power dissipation in NH systems, introduction of new dimensions, and the addition of new high-current fuse systems.

Applications

• Industrial Electrical Installations: The standard ensures reliable overcurrent protection in complex and demanding environments such as manufacturing plants, substations, and control panels where safety and continuity are paramount.
• Authorized Personnel Operations: Only qualified or specially trained staff may access or replace these fuse-links, reducing the risk of improper handling and electrical accidents.
• Compatibility and Interoperability: By providing standardized systems, the document supports interchangeable use of fuse-links and bases across European and international facilities, simplifying maintenance and upgrades.
• Panel and Equipment Builders: Assists OEMs, panel builders, and system integrators in selecting appropriate, compliant fuses for equipment intended for export or diverse user locations.
• Facility Upgrades and Retrofits: Guidance for upgrading protection devices in legacy industrial installations to meet updated safety and performance standards.

Related Standards

• IEC 60269-1: General requirements for low-voltage fuses, foundational for all fuse system specifications.
• IEC 60269-2:2013/A1:2016: International equivalent, detailing supplementary requirements for fuses for use by authorized persons.
• EN 60269 Series: Harmonized European standards for various low-voltage fuse applications.
• HD 60269-2: Core harmonization document for the European market, aligning IEC and EN standards.
