Hi
Can you give me some technical description of fuse supervision -(some relay or other method to monitorize fuse melting)?
Also some models and manufacturers?
Thanks.

There are 2 models needed:
1: for 3 HRC fuses 40-100 A. Fuse monitor has 1 NO+1 NC contact, used in control.
400 V AC.
2. for 220 VDC fuse, 6 A, to protect control voltage in LV switchboard drawers. Fuse must be small, for example bottle type.

I may be missing something, but could it be as simple as putting a general-purpose relay's coil in parallel with the fuse? We do this all the time in controls work at lower voltages.
In the olden days, we used to put a Sylvania Blue-Dot photo flash bulb in parallel with the fuses. You could tell at a glance what was blown -- and if you happened to be nearby when it happened, the flash of light would alert you to a problem.
Good on ya,

I found some solutions at Siba, Bussman- simple switches, and Jean Mueller- electronic relay.
