depending on kva class of the motor between 4-8 times the running current
you need the current of motor or the KW/HP rating
starting current of 315 kw motor in start delta 2.5 time for single sec. if your cable lingth 130 meter u can use 150mm2 (3 cable per phase) 150mm2 single cable current 292 Amp voltage drop 0.28/meters so u can use breaker 1000 Amp and set Im time (for starting current) setting avalible in breaker.
A 0.75 kW (750 W) single-phase motor operating at 220 V will typically have a full-load running current of about 3.4 A, calculated using the formula ( I = \frac{P}{V} ) (where ( P ) is power in watts and ( V ) is voltage). The starting current, or inrush current, can be significantly higher, often ranging from 4 to 7 times the running current, depending on the motor type and load conditions. Therefore, the starting current could be approximately 13.6 A to 23.8 A.
To answer these types of questions, a voltage of the single phase motor should be stated. It has to do with the breaker sizing and wire sizing and current load.

starting current of 3 phase 75 KW induction motor
Assuming the Motor is IE1 Efficiency and 4 Poles, the in rush current will be 1183 A
Well, isn't that a happy little question! To find the starting current for a 110 kW motor, you can use the formula: Starting Current = (Motor Power / (sqrt(3) x Voltage x Power Factor x Efficiency)). Remember, it's all about happy little calculations and making sure your motor has a smooth and joyful start.
The current depends on the supply voltage.
The starting current is high because the motor's rotor winding has very low resistance. It's similar to a transformer with a shorted secondary windings. As the motor accelerates,the back emf increases which resist the flow of current in the rotor winding. Hence,the current drop to the rated full-load value.

you need the current of motor or the KW/HP rating
It depends on what you mean by 'converter'; I'm not aware of such a machine. <<>> No, a 4 kW rotophase will not handle the start up current of a 4 kW 3 phase motor.

current = power/ voltage current = 3700/ 240 = 15.4 amps
Maximum current is defined by the rated KW of the device, say Motor. The motor may not run at its maximum rated capacity all the time. Nominal current is drawn when motor runs at nominal load.
