Three-phase motor current and starting analysis

Method and boundaries

Rated current = output power ÷ (√3 × line voltage × efficiency × power factor). Starting current applies the entered multiplier.

Protection selection, conductor ampacity, starter coordination, voltage dip and code compliance are not evaluated.
