IEC 60269-2:2006

The following characteristics of fuses are specified in addition to IEC Publication 269-1: - minimum rated breaking capacities; - time-current characteristics; - I2t characteristics; - standard conditions of constructions; - power dissipation and acceptance.

This standard is divided into six 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. Section VI: "gV" fuse-links with wedge tightening contacts. NOTE - The following fuse systems are standardized systems in respect to their safety aspects.

IEC 60269-2:2010 provides fuses for use by authorized persons are generally designed to be used in installations where the fuse-links are accessible to, and may be replaced by, authorized persons only. This standard is divided into fuse systems,(A thru I), each dealing with a specific example of standardized fuses for use by authorized persons. This fourth edition of IEC 60269-2 cancels and replaces the third edition published in 2006 and constitutes a minor revision. This part is to be used in conjunction with IEC 60269-1:2006, Low-voltage fuses - Part 1: General requirements and its Amendment 1 (2009). This Part 2 supplements or modifies the corresponding clauses or subclauses of Part 1. Where no change is necessary, this Part 2 indicates that the relevant clause or subclause applies. Tables and figures which are additional to those in Part 1 are numbered starting from 101.
