Calculating cascading on circuit breakers

Hey,
I am trying to work out the cascading on an old Merlin Gerin CM1600 circuit breaker. Basically, the product is so old that there are no cascade tables so I can't find out if the downstream breakers can withstand the fault current.

Does anybody know how to calculate this? I normally just rely on the tables - I have never been in a situation where I can't find the table.

Thanks
