The Siemens 3RT6024-1AP00 is a SIRIUS S0 power contactor rated for 23 kW at 400 V at 60 °C in AC-3e duty, which means it handles the full load of a 23 kW motor without derating at that ambient temperature. The AC-3e rating is the key figure for motor switching — it governs the contactor's ability to make and break locked-rotor current. For resistive loads (AC-1), the maximum switching rate is 1 000 1/h, while for motor duty (AC-3) it's also 1 000 1/h; the more severe AC-4 duty (plugging/reversing) is limited to 300 1/h. At 45 mm wide, it occupies a single 9 mm pitch unit on the rail — standard for the S0 frame size. Main and auxiliary circuits both use screw-type terminals, accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire. The main contact minimum cross-section is 10 mm² at both 40 °C and 60 °C, so you don't need to upsize the cable for higher ambient. Coil draws 6 A at 24 V rated value, 1 A at 110 V, 0.3 A at 220 V, and 10 A at 230 V — these are inrush figures typical for the S0 coil family.
Substance prohibitance per RoHS/REACH applies from 05/01/2012, so the part is compliant with current EU substance restrictions.
Integration Notes
The 45 mm width per unit means a 4-contactor group fits in 180 mm of rail — useful for compact motor control centers.
