1.1 Scope and object
Add after Note 2
NOTE 3 IEC 60269-6 (Low-voltage fuses – Part 6: Supplementary requirements for fuse-links for the protection of
solar photovoltaic energy systems) is dedicated to the protection of solar photovoltaic energy systems.

1.2 Normative references
Replace the reference to “IEC 60269-3:2006, 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” by the following:
IEC 60269-3, 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
Replace “I” by “J” at the end of the following reference:
