How many amps does a 100 HP 3 phase motor draw?

Here are the Full Load Amp (FLA) values for typical 230VAC and 480VAC 3 phase motors.

Motor horsepower Full load amps 230VAC Full load amps 460VAC
100 245 123
125 310 155
150 360 180
200 480 240

How do you size a circuit breaker for a motor?

You must size the overloads no more than 115% to 125% of the motor nameplate current rating, depending on the conditions [430.32(A)(1)]. You must size the short-circuit ground-fault protection device from 150% to 300% of the motor FLC [Table 430.52].

How do you calculate motor overload current?

The overloads are determined using 125% of the FLA, 7A x 1.25 = 8.75A. The maximum allowable size for the overloads is 9.8A. The overloads can be sized at 140% of the FLA if the overloads trip at rated load or will not allow the motor to start, 7A x 1.4 = 9.8A.
