Is There Any NT/NH Fuses For DC Current 56v DC ?

 

If you would define "NT" and "NH" and explain what you are trying to protect,
and why you need a Fuse with those specifications,
maybe you'd get a response.

 

Hello,

The NT/NH fuses seem to be those knive fuses:
NT/NT fuses

56v DC is about 80a, Is there any good protection for that ?, negative side is earth grounded also I have DC MCB with recloser function, but I want to add some extra layer for DC Fuse something like NT Fuse but for DC current

 

Maybe this can explain it for you - https://www.powerelectronics.com/te...ht-overcurrent-protection-for-dcdc-converters

Or this - https://www.swe-check.com.au/editorials/nh_fuses.php From this one it looks like you have to chose the correct type for the circuit you have, there looks to be a letter /number code for different uses.

You don't see many NT/NH fuses any more, They use a special replacing tool to remove the fuses from the knife links.
Can you use any other type, if this is a new installation?
Max.
