Calculation Breakdown
Suggested Product Category
Results are for preliminary estimation only. Final selection should be confirmed based on project specifications and engineering review.
Three-Phase Formula
kVA = (√3 × V × I) / 1000 × (1 + margin)
Single-Phase Formula
kVA = (V × I) / 1000 × (1 + margin)
Standard Sizes
Recommended size is the next IEC standard size above your calculated load.
