OLD Crabtree / MK MCB Interchangeability

[PC Electrics]

Do any of the "old hands" here know whether the old style MK MCBs (LN series) like this one:

will fit into an old Crabtree SB6000 board, which takes these MCBs:

Reason for asking is that I've got to RCD a socket circuit fed from a SB6000 and I have an MK LN RCBO I can use to make a neater solution than an off board RCD.

not directly - the busbar is different. for the MK you have, its 'forked'. sor the crabtree, its solid, with slots for the MCB screw
