Fuse size and type for 230V / 110V transformer

Can someone confirm if in place of FUSE 1 ca be used 25A RCBO Type D and in place of FUSE 2 16A MCB Type C  please?

Wall mounted transformer is 3.3kVA 230V/110V as per the below snapshot. 

Will 4mm2 singles H07 be fine on the primary and secondary side of the transformer if we don't consider any major voltage drop?
