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 J (IEC 60269-2:2010, modified)
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. 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 L 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)
NOTE The above-mentioned fuse systems are standardized systems in respect to their safety aspects. The National Committees may select from the examples of standardized fuses one or more systems for their own standards.

La CEI 60269-2:2010 donne les fusibles destinés à être utilisés par des personnes habilitées 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. Cette quatrième édition de la CEI 60269-2 annule et remplace la troisième édition parue en 2006 et constitue une révision mineure. La présente partie doit être utilisée conjointement avec la CEI 60269-1:2006, Fusibles basse tension - Partie 1: Exigences générales et son Amendement 1 (2009). Cette Partie 2 complète ou modifie les articles ou paragraphes correspondant de la Partie 1. Lorsqu'aucune modification n'est nécessaire, la Partie 2 indique que l'article ou le paragraphe approprié est applicable. Les tableaux et les figures qui sont complémentaires à ceux de la Partie 1 sont numérotés à partir de 101. Les annexes complémentaires sont numérotées AA, BB, etc.
Nizkonapetostne varovalke - 2. del: Dodatne zahteve za varovalke, ki jih uporabljajo strokovne osebe (uporaba varovalk zlasti v industriji) - Primeri tipov standardiziranih varovalk od A do J (IEC 60269-2:2010, spremenjen)
Varovalke, ki jih uporabljajo strokovne osebe, so običajno zasnovane za uporabo pri napeljavah, kjer so vložki varovalk dosegljivi zgolj strokovnim osebam, ki jih tudi edine lahko menjavajo. Varovalke, ki jih uporabljajo strokovne osebe in so v skladu z naslednjimi sistemi varovalk, so prav tako v skladu z zahtevami ustreznimi podklavzulami IEC 60269-1, razen če je v tem standardu drugače opredeljeno. Ta standard je razdeljen na sisteme varovalk, pri čemer vsak obravnava določen primer standardiziranih varovalk, ki jih uporabljajo strokovne osebe:
Sistem varovalk A: varovalke z vložki z nožastimi kontakti (NH sistem varovalk).
Sistem varovalk B: varovalke z zapiralnimi vložki z nožastimi kontakti (NH sistem varovalk).
Sistem varovalk C: zapahi v varovalkah (NH sistem varovalk).
Sistem varovalk D: osnove varovalk za namestitev zbiralke (NH sistem varovalk).
Sistem varovalk E: varovalke z vložki za vijačne spoje (BS vijačni sistem varovalk).
Sistem varovalk F: varovalke z vložki, ki imajo cilindrične kontaktne kapice (NF sistem cilindričnih varovalk).
Sistem varovalk G: varovalke z vložki z stranskimi nožastimi kontakti (BS sistem varovalk).
Sistem varovalk H: varovalke z vložki, ki imajo »gD« in gN« značilnosti (razred J in časovna zakasnitev razreda L in vrste varovalk brez časovne zakasnitve).
Sistem varovalk I: gU vložki varovalk s kontakti za zategovanje z zagozdo.
Sistem varovalk J: varovalke z vložki, ki imajo značilnosti »gD razreda CC« in »gN razreda CC« (časovna zakasnitev razreda CC in vrste varovalk brez časovne zakasnitve).
OPOMBA: Zgoraj navedeni sistemi varovalk so glede na njihovih varstvene vidike standardizirani sistemi. Nacionalni odbori lahko izberejo med primeri standardiziranih varovalk enega ali več sistemov za svoje lastne standarde.
