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.
