The Siemens 3RT1036-3AR60 is a SIRIUS S2 power contactor — screw-type main terminals, 55 mm wide, sized for motor loads up to 30 kW at 500 V and 22 kW under AC-2 duty at 400 V.
The 30 kW at 500 V figure governs motor switching under AC-3 duty (squirrel-cage motors, normal starting). Auxiliary contact ratings span 10 A at 24 V down to 0.3 A at 220 V — enough for PLC inputs or relay coils in the control circuit.
Screw terminals accept solid conductors 2x (0.25…2.5 mm²) and stranded up to 2x (0.75…25 mm²). Storage range -55 to +80 °C, operating -25 to +60 °C, pollution degree 3.
