摘要:
Fuses for use by authorized persons are generally designed to be used in installations wherethe fuse-links are accessible to, and may be replaced by, authorized persons *** for use by authorized persons according to the following fuse systems also comply withthe requirements of the corresponding subclauses of IEC 60269-1, unless otherwise definedin this *** standard is divided into fuse systems, each dealing with a specific example ofstandardized 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 fusesystem)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 andclass L time delay and non time delay fuse types)Fuse system I: gU fuse-links with wedge tightening contactsFuse 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)
