Motors should run a minimum of one minute to dissipate heat build up from starting current. Six inch and larger motors should have a minimum of 15 minutes between starts or starting attempts. 1. Minimize the frequency of starts, preferably to fewer than per 24-hour period. Six and eight inch motors should have a minimum of 20 minutes between starts

Look at the table of motor kW to cable size chart. The chart is prepared based on the direct online start and star-delta starting. Note that, using aluminium cable for low rating motor up to 1.5kW/2HP motor is not recommended. Here 2R indicates Two Run cables. The cable size chart is suitable for both single-phase and three-phase.

Assuming it is a three phase motor current will be 1.732 amps per KW per phase at full load. Cable amperage should be 2.5 times HP at 25′C ambient. 75KW = 100 HP. MCCB (Inductive grade also 2.5 times the HP. You have not mentioned how you are going to start? I recommend soft-starter.
