Rated to 63 amp?

These look like standard Merlin Gerin forks from the 1970s/80s From memory they did breakers up to 50 amps which connected with these forks so might be OK for 63 amps.
Might be worth seeing if your supplier has an old M.G. catalog & spec book

As an observation over the years, they tend to be wider or fatter than AC only MCBs....

just like the rest of us. wider and fatter over the years. LOL.

the c60 fuses are good for dc . the other mcbs ( the c45n) are being replace with the c60hb fuses anyway that will will work as the table below shows.

If it was just a one-off, I think that I'd make my own fork from a bit of copper bus bar. Shouldn't take too long with hacksaw and drill. Doesn't need to be as nicely shaped as the others. If you need a few, a local small engineering company would make them to a sketch. More expensive than off the shelf, of course (if you coud find any).

Yeah we own a fabrication buisness but just dont know if this will be a one off. a price comparison would help, ive looked everywhere for something similar but no success
