It carries a 22 kW rating at 500 V and 11.4 kW at 690 V, with an AC-2 motor rating of 18.5 kW at 400 V — figures that tell you it handles medium-horsepower induction motors on 400 V to 690 V three-phase systems. The screw-type terminals accept solid conductors up to 2x 4 mm² or stranded up to 2x 25 mm², so it mates directly to standard motor-circuit wiring without lug adapters.
The AC-1 maximum switching rate of 1,200 operations per hour applies to resistive loads (heaters, lighting); AC-3 drops to 1,000 ops/h for standard squirrel-cage motor starting; AC-4 (plugging/inching) is limited to 300 ops/h. Pollution degree 3 means it tolerates conductive dust and occasional condensation, typical for industrial enclosures not in clean-room environments.
