Weband the motor’s Service Factor (SF), should be sized at 115% or less of motor FLA for 1.0 SF or 125% or less of motor FLA for 1.15 or greater SF However, as shown in Curve 2, when fast-acting, non-time-delay fuses are sized to the recommended level the motors inrush will cause nuisance openings. Motor Protection Basic Explanation Motor ... WebSuppose we have a 3-phase induction motor with a power rating of 15 kW and is connected to a power supply of 415 V. The power factor of the motor is 0.85. We can calculate the amp rating of the motor as follows: Amp Rating = (15,000 × 1000) / (√3 × 415 × 0.85) = 24.98 A. Therefore, the amp rating of the motor is 24.98 A.
