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

How do you size an electric motor breaker?

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].

What is full load amps on a motor?

Full Load Amps, or F.L.A., represents the amount of current the motor is designed to draw at the rated horsepower. In the example nameplate, this means that when the motor is running under a full load at 230 volts, we can expect it to draw 5.4 amps.

How many HP is a 15 amp motor?

At 100% efficiency, the most a 15-amp, 120v outlet in a home circuit can supply is 15 x 120 or 1800w; 1800 divided by 746 equals 2.41 hp.

What is the full load current of HP motor?

25 A	3.62 HP	90%
30 A	4.34 HP	90%

How many amps does a 50 hp motor use?

AC Motor Full Load Amperes

HP	200 Volts	440-480 Volts
40	120	52
50	150	65
60	177	77
75	221	96

How do you calculate motor overload protection?

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.
