It's rated for 22 kW at 400 V in AC-2 duty (slip-ring motor starting) and 41 A in AC-4 duty (plugging/inching), with a 30 kW rating at 500 V for standard squirrel-cage motors.
At 55 mm wide and 112 mm tall, it fits standard panel layouts with side-by-side mounting permitted — no derating gap needed. The front face carries an IP20 rating; the terminals themselves are IP00, so keep fingers and tools clear when live.
