Suitable fuse for 50v low current circuit

[wedwo1]

I have a DC-DC converter (50v to 5v) and have it connected to my 50v inverter battery circuit (200a capacity). The device consumes less than 1a. I'd like to use an in-line barrel fuse or other suitable protection in line on the positive but am struggling to find something low current in the 50v DC range. What should I be using?

”200a capacity” inverter line probably has pretty high short-circuit so you need enough breaking capacity.
6,3x32mm ceramic fuse likely, for example:
