Foreword
The text of document 32B/484/FDIS, future edition 3 of IEC 60269-3, prepared by SC 32B, Low-voltage
fuses, of IEC TC 32, Fuses, was submitted to the IEC-CENELEC parallel vote.
A draft amendment, containing common modifications to document 32B/484/FDIS, was prepared by
Reporting Secretariat CLC/SR 32B, Low-voltage fuses, and was submitted to the formal vote.
The combined texts were approved by CENELEC as HD 60269-3 on 2007-03-01.
This Harmonization Document partially supersedes EN 60269-3:1995 + A1:2003 and also supersedes
HD 60269-3-1:2004.
This document is to be used in conjunction with EN 60269-1:2007.
This Part 3 supplements or modifies the corresponding clauses or subclauses of Part 1.
Where no change is necessary, this Part 3 indicates that the relevant clause or subclause applies.
The following dates were fixed:
– latest date by which the HD has to be implemented
at national level by publication of a harmonized
(dop) 2008-03-01
national standard or by endorsement
– latest date by which the national standards conflicting
(dow) 2010-03-01
with the HD have to be withdrawn
Tables and figures which are additional to those in Part 1 are numbered starting from 101.
Annex ZA has been added by CENELEC.
