Since the small starters can't handle large let through currents of a short circuit on a 100A breaker (the contacts weld together),
The short circuit current let through by a 100 amp breaker is virtually identical as the short circuit current let through by a 15 amp breaker.
I've seen a lot of size 0, or 00, starters running downstream from a 30 amp breaker, even though the manual starter labels clearly disallow anything more than 15 or 20 amp short circuit protective device. This is a common violation.
You lost me there, are you sure you are not thinking of the ratings of any auxiliary contacts?
