It is rated for motor switching at 11 kW in AC-2 duty at 400 V, and carries the same power rating at 500 V and 690 V — so it handles standard 400 V three-phase motors and also works on 480 V or 600 V class systems without derating the power.
The coil draws 10 A at 24 V rated value, dropping to 0.3 A at 220 V; these are the holding currents, not inrush, so size your control transformer for the inrush peak. The front face carries IP20 finger protection; the terminals themselves are IP00, so they must be inside an enclosure.
Short-circuit coordination and wiring
The main circuit terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) for the control circuit; the main terminals take up to 2x 10 mm² or 1x 8 AWG. Strip length and ferrule sizing follow standard Siemens practice for screw terminals — torque to the value printed on the contactor.
