VoltageVolts): 240V. Maximum 1 Phase Power per Phase = 200 x 240. 48,000 Volt Amps (VA) per Phase or. 48 Kilowatts (KW) per Phase. Maximum 3 Phase Power = 200 x 415 x 1.732. 144 KVA Kilovolt Amps or. 144 KW Kilowatts. 240V power is used in the US and parts of the world. In the US 120 / 240V 1 Phase 3 Wire is the standard for homes and 240V 3 Thewire size chart below shows allowable ampacities of insulated conductors rated up to and including 2000 Volts, 60°C through 90°C (140°F through 194°F), not more than three current-carrying conductors in raceway, cable, or earth (directly buried), based on ambient air temperature of 30°C (86°F). Wire Size Chart and Maximum Amp Ratings I= kVA x 1000 ÷ (3 x VL-L) Where: S = Apparent Power in Volt-Amps. V = Voltage in Volts. I = Current in Amperes. VL-L = Line to Line Voltage in 3-Phase Circuits. VL-N = Line to Neutral Voltage in 3-Phase Circuits. Forany three-phase AC circuit, Current, I = 1000 x kW / (3 x V ph x P.F.) Where V ph is the RMS value of the applied phase voltage and P.F. is the power factor of the load. Therefore, amps can be calculated from AC - kW by dividing kW by 3 times the product of the RMS value of applied phase voltage, power factor and multiplying it by 1000. Thecurrent rating is amps per pole for the power poles. If there are auxiliary contacts, they will have a lower amps per pole rating. If a contactor is rated for use with either single-phase or three-phase motors, it would have a single-phase and three-phase power rating. The power ratings would also be stated separately for each motor Wehave a circuit with 25kW three-phase power generator, 80% efficiency (0.8 PF) at 240volts. The amps will be: amps = (kW × 1,000) ÷ (√3 × PF × volts) amps = 75.18A. kW to Amps Conversion Table. You can find the amps value from known kilowatts in the tables below: DC Kilowatts to Amps (kW to Amps). kW to Amps Conversion Table at 110V DC .
