It delivers 22 kW at 400 V in AC-2 duty (slip-ring motors, reversing starts) and 30 kW at 500 V in AC-3 duty (squirrel-cage motors, normal starts).
AC-2 at 400 V rated at 22 kW — that covers reversing or plugging duty on slip-ring motors up to that power. AC-3 at 500 V rated at 30 kW handles normal starting of cage motors. The contactor is rated for 800 operations per hour in AC-3, so it keeps up with moderate cycling on conveyors or pumps without overheating. The front is IP20 (finger-safe), the terminal area is IP00 — wire connections are exposed, so keep live parts behind a panel door or cover. Screw terminals accept solid wire up to 2x (0.5...1.5 mm²) and stranded up to 2x (0.75...25 mm²). That's generous for the main power circuit — no need for pin lugs on 16 mm² stranded unless your local code requires them.
