In order to properly set up programmable motor protection, it is necessary to know the locked rotor current of a motor. Given the illustrated chart of code letters for locked-rotor kVA/HP and the necessary instructions, calculate the estimated locked rotor current for the motor represented by the illustrated motor nameplate using a mid-range value for the code letter, assuming the motor is to run at 440 VAC. See illustration EL-0175.
