For standard AC-2 motor starting (slip-ring rotors) it's rated 45 kW at 400 V. The 55 kW rating at 500 V and 25.4 kW at 690 V tell you this contactor handles higher-voltage drives without stepping up a frame size. The 70 mm width and 146 mm height fit the S3 footprint; depth is 139 mm, so check gland-plate clearance if the panel is shallow. Side-by-side mounting is permitted, which saves rail space in multi-contactor groups but watch the thermal derating when packing them tight. Arcing time runs 10 to 25 ms at AC, with a tighter 10 to 15 ms window for the arc itself. Accepts solid wire 2x (0.25 to 2.5 mm²) for control wiring and stranded 2x (10 to 50 mm²) for power — that's a wide range covering most motor feeds up to the S3 rating. The intermediate terminal also handles 2x (2.5 to 16 mm²) solid or stranded, giving flexibility for mixed-gauge connections in the panel.","metaTitle":"Siemens 3RT1046-3AB00 SIRIUS Power Contactor, S3, 80A AC-4","metaDescription":"Siemens SIRIUS 3RT1046-3AB00 power contactor, S3 size, 80A AC-4 at 400V, 55kW at 500V.
