I am trying to understand the spec of a Datasheet of a thermal fuse. for example the one below :
from the datasheet: http://www.farnell.com/datasheets/2244108.pdf
I see the temperature at which it fuses. But there is also a rated current.
my initial understanding was that if the current through the fuse is higher than this rated current , the fuse would blow.So basically, my reasoning was that the thermal fuse can then also be used as electrical fuse.
However, I did an experiment with my PSU where I was passing 2.5A through a similar fuse, but it still did not fail. The fuse in the test was rated 1A.
so my question is :
what is this rated current provided in the datasheet?
