Low-voltage fuses - Part 3: Supplementary requirements for fuses for use by unskilled persons (fuses mainly for household or similar applications) - Examples of standardized systems of fuses A to F (IEC 60269-3:2010, modified)
Fuses for use by unskilled persons according to the following fuse systems comply with all subclauses of IEC 60269-1 and with the requirements laid down in the relevant fuse systems. This standard is divided into six fuse systems, each dealing with a specific example of standardized fuses for use by unskilled persons:
- Fuse system A: D type fuse system
- Fuse system B: Cylindrical fuses (NF cylindrical fuse system)
- Fuse system C: Cylindrical fuses (BS cylindrical fuse system)
- Fuse system D: Cylindrical fuses (Italian cylindrical fuse system)
- Fuse system E: Pin-type fuses
- Fuse system F: Cylindrical fuse-links for use in plugs (BS plugtop fuse system)
NOTE 1 Examples of standardized fuses complying with the requirements of IEC 60269-1 are listed in the present standard. Other examples may be added, provided that they comply with these requirements. For recommendations for future designs of fuses, see Annex CC. NOTE 2 The following fuse systems are standardized systems with respect to their safety aspects. The National Committees may select from the examples of standardized fuses one or more systems for their own
standards. Colour codes are not specified for each fuse system. Where colour codes are indicated, they apply only to that particular fuse system.

La CEI 60269-3:2010 donne exigences supplémentaires pour les fusibles destinés à être utilisés par des personnes non qualifiées qui appartiennent aux systèmes de fusibles suivant répondent à l'ensemble des paragraphes de la CEI 60269-1, ainsi qu'aux exigences énoncées dans les systèmes de fusibles qui leur sont applicables. La présente partie doit être utilisée conjointement avec la CEI 60269-1, Fusibles basse tension - Partie 1: Exigences générales. Lorsqu'aucune modification n'est nécessaire, la Partie 3 indique que l'article ou le paragraphe approprié est applicable.
Nizkonapetostne varovalke – 3. del: Dodatne zahteve za varovalke, ki jih uporabljajo nestrokovne osebe (uporaba varovalk zlasti v gospodinjstvu in podobnih okoljih) - Primeri standardiziranih sistemov varovalk od A do F (IEC 60269-3:2010, spremenjen)
Varovalke, ki jih uporabljajo nestrokovne osebe, v skladu z naslednjimi sistemi varovalk ustrezajo vsem podklavzulam IEC 60269-1 in zahtevam, določenim v primernih sistemih varovalk. Ta standard je razdeljen na šest sistemov varovalk, pri čemer vsak obravnava določen primer standardiziranih varovalk, ki jih uporabljajo nestrokovne osebe:
- Sistem varovalk A: vrsta D sistema varovalk.
- Sistem varovalk B: cilindrične varovalke (NF sistem cilindričnih varovalk).
- sistem varovalk C: cilindrične varovalke (BS sistem cilindričnih varovalk).
- Sistem varovalk D: cilindrične varovalke (sistem italijanskih cilindričnih varovalk).
- Sistem varovalk E: varovalke iglaste vrste.
- Sistem varovalk F: cilindrični vložki varovalk za uporabo v vtičih (BS sistem varovalk pri kabelskem vtiču).
OPOMBA 1: Primeri standardiziranih varovalk, ki ustrezajo zahtevam IEC 60269-1, so našteti v pričujočem standardu. Drugi primeri se lahko dodajo pod pogojem, da ustrezajo tem zahtevam. Za priporočila za prihodnje načrte varovalk glej Dodatek CC. OPOMBA 2: Naslednji sistemi varovalk so glede na njihove varstvene vidike standardizirani sistemi. Nacionalni odbori lahko izberejo med primeri standardiziranih varovalk enega ali več sistemov za svoje lastne standarde. Barvne kode niso opredeljene za vsak sistem varovalk. Kjer so navedene barvne kode, veljajo zgolj za ta posamezni sistem varovalk.
