Chart Notes:
L-L and L-N identifies voltage levels as measured from Line to Line or Line to Neutral respectively.
Power Factor PF = KW / KVA, and is the ratio of True Power to Apparent Power.
Power Factor Rating: Amps shown above are at 0.8PF rating. Actual load PF may differ.
Abbreviations: KVA : Kilo Volt Amperes; KW: Kilowatts; PF: Power Factor; L-L: Line to Line; L-N: Line to Neutral
Chart Instructions:
Find KVA & KW Rating
To find the KVA or KW rating (at 0.8PF) for your application, select the 50HZ three phase L-L (line to line) voltage level being utilized.
Scan down this column to the current needed for your application (select the next higher current rating for more margin). Scan the
row to the left and find the KVA and KW rating needed.
Find Current Rating
To find the phase current rating if the 50HZ load KW or KVA is known, select the known KVA or KW rating on the chart above. Scan
across the row to the right until the three phase L-L (line to line) voltage being utilized column is reached.
Useful Electrical Formulas
KVA = Volts x Amps x 1.732
1,000
KW = KVA x Power Factor (PF)
Amps (When KVA is Known) = KVA x 1,000
Volts x 1.732
Amps (When KW is Known) = __________KW x 1,000_______
Volts x Power Factor (PF) x 1.732
