The 690 V rating (38.2 kW) extends its reach to 690 V line supplies common in heavy industrial sites. For resistive loads (AC-1), it can switch up to 650 operations per hour. The S3 frame size means it occupies the same DIN footprint as other SIRIUS S3 contactors — a direct panel swap if your existing S3 unit fails. ## Panel Integration & Wiring Dimensions: 146 mm height, 70 mm width, 139 mm depth — fits standard S3 panel cutouts. Main circuit terminals accept solid conductors up to 2x 4 mm² or stranded up to 2x 50 mm² (derated to 35 mm² at 60 °C). Control terminals accept 0.5–4 mm² solid or stranded. The contactor can be snapped onto 35 mm or 75 mm rail — no tools needed for the snap-on method.","metaTitle":"Siemens 3RT1446-1AP60 SIRIUS Power Contactor, S3, 22 kW AC-2","metaDescription":"Siemens 3RT1446-1AP60 SIRIUS power contactor, size S3, rated 22 kW AC-2 at 400 V, 38.2 kW at 690 V.
