The 230 V AC coil (rated value 230 V) is a standard control voltage for many industrial zones. The AC-4 rating (41 A at 400 V) matters for reversing or inching duty where the contactor makes and breaks under full load; the 300 operations per hour maximum in AC-4 reflects the thermal stress of that cycle. For DC switching, the contactor is rated at 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V. These are the make/break currents for DC loads — a critical check if you're switching solenoids or DC brake coils, because DC arcs are harder to extinguish than AC. The main circuit accepts stranded wire up to 2x (0.75... 25 mm²) and solid wire up to 2x (0.25... 2.5 mm²). The auxiliary circuit accepts 2x (0.75... 16 mm²) solid or stranded. The minimum permissible cross-section at 40 °C is 16 mm² — that's the smallest wire you can run at full rated current without exceeding terminal temperature rise. The contactor is rated IP20 on the front (finger-safe) and IP00 at the terminals, so it requires a panel enclosure or additional finger protection at the wiring points.","metaTitle":"Siemens 3RT1036-3BP40 SIRIUS Power Contactor, Size S2, 230 V","metaDescription":"Siemens SIRIUS 3RT1036-3BP40 power contactor, size S2, 230 V AC coil, screw terminals, 30 kW at 500 V AC-3, IP20 front.
