SCCR fuse rating after rectifier UL 508A UL 61800-5-1

SCCR fuse rating after rectifier UL 508A UL 61800-5-1

(OP)
Hello,
I'm new to the forum and as well kind of to the UL word - so I'm not sure if I'm right here and if anybody has experience in these kind of issues.
My question is regarding required fuse SCCR rating in a dc link measurement branch of an AC voltage source converter. My SC rating from the source is 3 Phase 400V and about 80kA. What this means for the fuse rating which is protecting a measurement line branching of the dc link which is connected to the source by a six pulse diode rectifier. Please post your question if more inputs are required to clarify. Does anybody knows some guidance from UL side in this issue? thx
