At 400 V, that translates to 55 kW of motor power. The 24 V AC coil (50/60 Hz) pulls in reliably across the standard control voltage found in many European and Asian panel designs. Size S3 means this contactor occupies a defined physical footprint in the SIRIUS modular system — it's a mid-frame size, not the compact S0 or the larger S6/S10 frames. The screw terminals accept standard power and control wiring without special tooling. RoHS compliant since 31 July 2018, and REACH Article 33 duty-to-inform data is available. No export restrictions apply (AL: N, ECCN: N). The manufacturer provides the standard compliance documentation pack with the shipment.","metaTitle":"Siemens 3RT2047-1AC20 SIRIUS Power Contactor, 110 A AC-3, 24","metaDescription":"Siemens SIRIUS 3RT2047-1AC20 power contactor, 110 A AC-3e/AC-3, 55 kW at 400 V, 3-pole, 24 V AC coil, 1 NO + 1 NC aux, screw terminals, size S3.
