Rated for AC-2 duty at 45 kW and AC-4 at 80 A, both at 400 V, this contactor handles slip-ring motor starting (AC-2) and plugging/reversing (AC-4) without derating the main poles. The AC-3 maximum switching frequency of 850 operations per hour suits conveyor and pump cycling. ## Termination and wiring constraints Solid conductors accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²). Stranded conductors accept 2x (10 to 50 mm²). Solid or stranded mixed terminations are 2x (2.5 to 16 mm²). Switching times: arcing time 10 to 15 ms, total operate time at AC 10 to 25 ms. The coil holds at 24 V nominal; dropout occurs below the undervoltage threshold typical of 24 V control systems. Auxiliary contact ratings: 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, 6 A at 230 V, 3 A at 400 V, covering both 24 VDC and AC control circuits. Mechanical life typical 10,000,000 operations. The S3 frame shares the same rail footprint as other SIRIUS contactors, allowing mixed sizes on the same DIN rail.","metaTitle":"Siemens 3RT1046-1AB00-1AA0 SIRIUS Power Contactor, S3, 45 kW","metaDescription":"Siemens SIRIUS 3RT1046-1AB00-1AA0 power contactor, Size S3, 45 kW at 400 V AC-2, 80 A AC-4.
