hager1361 cartridge fuses

[driverman]

Afternoon Guys. Question from an out of date retired electrician.
Existing Hager split-board using cartridge fuses (1361) for OC protection.
Existing shower circuit (6mm) protected by 30amp cartridge fuse for old possibly 7'5kw shower unit.
Shower being replaced with a 8.5kw shower unit. Are there 40 amp cartridge fuses /holders still available? If not, would a Hager 40 amp Hagar MCB fit same board? Cable clipped surface (not buried in walls, insulation etc)
