About This Item
Full Description
IEC 60269-1 applies with the following supplementary requirements.
Fuse-links for the protection of semiconductor devices shall comply with aIl requirements of IEC 60269-1, if not otherwise indicated hereinafter, and shall also comply with the supplementary requirements laid down below.
These supplementary requirements apply to fuse-links for application in equipment containing semiconductor devices for circuits of nominal voltages up to 1 000 V AC or 1 500 V DC. For some fuse-links higher rated voltages can be used.
NOTE Such fuse-Iinks are commonly referred to as "semiconductor fuse-links".
The object of these supplementary requirements is to establish the characteristics of semiconductor fuse-links in such a way that they can be replaced by other fuse-links having the same characteristics, provided that their dimensions are identical. For this purpose, this standard refers in particular to
a) the following characteristics of fuses:
1) their rated values
2) their temperature rises in normal service
3) their power dissipation
4) their time-current characteristics
5) their breaking capacity
6) their cut-off current characteristics and their I2t characteristics
7) their arc voltage characteristics
b) type tests for verification of the characteristics of fuses
c) the markings on fuses
d) availability and presentation of technical data (see Annex BB).
