AS 2005.40:1989 pdf download.Low voltage fuses—Fuses withenclosed fuse-links Part 40: Supplementary requirements for fuse-links

for the protection of semiconductor devices.

The time-current characteristics of a fuse-link vary according to its design and ako, for a given fuse-link. depend on the ambient temperature and the cooling conditions.

The manufacturer shall provide time-current characteristics based on an ambient temperature of 20°C to 25°C in accordance with

the conditions specified in Sub-clause 8.3. The time-current characteristics of interest are the pre-arcing characteristic and

operating characteristics having voltage as a parameter. The time-current characteristics are stated for rated frequency.

For d.c. they are slated for time constants according to Table XIIB.

For some applications, and in panicular for the higher values of prospective current (shorter times), the same information may be

presented in the form of ft characteristics, It is recommended that in this region. 12, characteristics shall be given as an

alternative or in addition.
