Derived Ratings (calculated from the configuration)

The values below are computed from what you selected above. Anything that cannot be computed yet is shown as an em dash — never as zero.

Iₙ = S / (√3·U) · I_sc = 100·Iₙ / uₖ · S_sc = √3·U·I_sc · I_p = k·Iₖ

Still required to complete the calculation: rated capacity S, impedance voltage uₖ, short-time or peak withstand current.

Per-model values (P0 / Pk / uₖ declared by the factory, losses, noise, temperature rise, dimensions, weight) are not in the product library: those rows stay at an em dash until the factory parameter sheet is supplied. An em dash means the value is unavailable — it is never rendered as zero.
