If a slow 100mA is what you need, then you may get similar protection from a fast 200mA.

That is not all that far from fast 500mA.

Can you see where my suggestions and comments are going?

Any fast 500mA fuse is safer than no fuse.
If you can't get a 500Vdc rated fuse as low as T100mA then maybe an F500mA would be the next best.
Will go between the tube HV PSU 350VDC & SSHV2 30mA

I entered the specs at the Littelfuse site and this and this were the only items returned.

Try a Peavey or Marshall or Behringer guitar amp repair facility. Guitar amp people tell me tube guitar amps use B+ fuses all the time. I see using a 250 VAC rated fuse on 400 VDC as marginal. I use fireproof B+ resistors myself, Hint - 47 ohms 3 w is not big enough for a 5AR4 rectifier. Goes so hot it becomes transparent.

i hope you also size the fuse for the voltage rating of the power supply when it is unloaded.

Because when a fuse blows its unloading the power supply.
