Calculate amps, hp and kVA

The calculators below can be used to calculate electric motor amps, horsepower and 3-phase kVa.

Calculate Current (amps)

Calculate Power (horsepower)

Calculate 3 Phase Apparent Power (kVA)

RLA - 'Running Load Amps' - current drawn during normal operation of electric motor.
FLA - 'Full Load Amps' - amount of current drawn when full-load torque and horsepower is reached for the motor. FLA is usually determined in laboratory tests. Note! - in the calculator above FLA is RLA + 25%.
1 hp = 0.745 kW
