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. WebSince the overload current rating cannot be greater than 125% of the FLA, engineers can choose the next lower circuit breaker rating, for example, 31 A. Note: Motor full load amperage ratings can easily be obtained from the motor nameplate or through calculations. Engineers can also obtain these ratings by contacting motor manufacturers. foam air conditionerWeband 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.
