If this where a true 7 Hp motor (It's not, they don't build 7 HP motors standard) you could use a 100 amp breaker for this motor. NEC Article 430.52.
I used 7.5 HP for the calculation as that is the closest NEMA size listed in the NEC.
You should look at the instructions and see what the manufacturer recommends for the breaker (OCPD) size. Call them if you must.
