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.
