BS HD 60269-3:2010+A1:2013

Low-voltage fuses. Supplementary requirements for fuses for use by unskilled persons (fuses mainly for household and similar applications). Examples of standardized systems of fuses A to F | Status: Current, Superseded

1 General scope 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 intofourfuse systems, ms, 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)

Text deleted

• • 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 in respect to their safety aspects. The National Committees shall select at least one complete fuse system of this standard for their national standards. Colour codes are not specified for each fuse system. Where colour codes are indicated, they apply only to that particular fuse system.
