How to use this data
Single phase S=VI; balanced three-phase S=√3VLLI. P=S×PF; reactive magnitude=S√(1−PF²), all divided by 1000 for k-units. Electrical input power is not shaft output.
CHECK THE METHOD
Worked example
400 V line-to-line, 10 A and PF 0.8 gives 6.9282 kVA, 5.54256 kW and 4.15692 kvar magnitude.

Common lookup questions
What should I confirm before using this lookup?
Not an ampacity, breaker, protection or installation-code selection. Verify the actual electrical system and equipment nameplate; voltage-drop checks remain separate.
