(OP)
Hi,
I am trying to select a S&C vista device. Downstream of this device is a fused transformer rated at 2500kVA, 34500kV/480V. The transformer fuse is rated at 8A. The current on the primary side of the transformer is only 5A. Can I select a vista fuse rated at 100A? Is it too high?

I donot know why you are referring to S&C "VISTA" for 34.5 kV side fuse.As far as I know, VISTA is a model name of switchgear made by S&C.
If your application is outdoor,then you should have Model:SM-4,50E Amp (standard) fuse made by S&C.Verify non-fusing due to mag inrush with proper selectivity. 100 A fuse looks too high.If indoor select a current limiting model.
