規格概要 IEC 60269-2:2013+AMD1:2016+AMD2:2024 CSV 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:
