It carries a 41 A AC-4 rating at 400 V for demanding reversing and plugging duty, and delivers 30 kW at 500 V for standard three-phase induction motors.
For less severe AC-3 duty (start-run-stop), the 30 kW at 500 V gives you headroom for a 37 kW motor at 400 V (derating per Siemens selection tables).
The S2 footprint is 75 mm wide, 112 mm tall, 115 mm deep — plan for that depth when routing cables behind the panel. Screw terminals on the main circuit accept up to 16 mm² stranded (2x 0.75–25 mm²) or 2.5 mm² solid (2x 0.25–2.5 mm²). Side-by-side mounting is allowed with no derating gap, so you can pack several contactors on a rail for multi-motor groups.
