It delivers 38 kW at 400 V and 60 °C (AC-3e duty), which means it handles typical three-phase induction motors in that power band without derating for elevated ambient temperatures inside an enclosure. The screw-type main and auxiliary terminals accept 2x (0.75–16 mm²) solid or stranded copper, so no special lugging is needed for common motor feeder sizes.
