AC-3 motor switching at 500 V delivers 22 kW, and at 690 V it handles 11.4 kW. AC-4 at 400 V is rated 35 A for reversing or inching duty where the load is switched under full current. Terminals accept 2x (0.75 to 2.5 mm²) solid or 2x (0.75 to 25 mm²) stranded, with a maximum of 2x (0.75 to 4 mm²) solid on the smaller pair.
The S2 frame measures 55 mm wide, 112 mm high, and 179 mm deep — fits standard 55 mm-wide contactor slots on a DIN rail.
The built-in auxiliary contacts handle DC-13 loads at various voltages: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. For AC-15 control circuits they're rated 6 A at 230 V and 3 A at 400 V. These numbers govern the PLC output or relay it can drive directly — watch the DC-13 curve if you're switching solenoids or contactor coils in a 24 VDC control loop.
