Onderwerp: RE: [PSES] breakage of the fuse
Dear all,
Thank you for your comments.
The below mentioned construction was rejected. The client needs to use high
breaking fuse and not enhanced fuse.
The problem is that in every switch mode power supply you can

Peter,
Fuse is not replaceable. It needs to be sleeved (tubed)
and only manufacturer can repair the power supply.
Due to the tubing, there is not likely that vaporized
What is the breaking capacity of the fuse? Sounds like it may be a low breaking
capacity fuse. If it is you should change it to a high breaking capacity fuse.

Bostjan commented: During the abnormal tests in primary circuit,
internal input fuse operates and glass breaks. However, fuse is inside the
tubing and broken glass does not spread around.
Would you accept such construction?

Bostjan,
Such a question can have
When a fuse's interrupting (breaking) capacity is too low for an
application and the fuse opening interrupts current in a manner that
causes the glass to crack or break, the temperature gradient across the
glass and the internal pressure created by the plasma when the fusible
element vaporized can

Dear safety experts,
During the abnormal tests in primary circuit, internal input fuse operates
and glass breaks.
Yes do the test 3 times to check for repeatable results

Hello Bostjan:
I agree with John Woodgate. The fuse is being
used beyond its ratings. It cannot be relied
upon to interrupt the fault current.
