The Siemens 3RT1046-3AG60 is a SIRIUS S3-frame power contactor rated for motor loads up to 55 kW at 500 V and 25.4 kW at 690 V — the 690 V figure is the one that governs for 690 V line applications, not the 500 V number. Switching frequency varies by duty class: 900 cycles/hour at AC-1 (resistive), 850 at AC-3 (standard motor starting), 350 at AC-2 (slip-ring motors), and 250 at AC-4 (plugging/inching). For a conveyor drive running AC-3 duty, the 850 cycles/hour limit is the one that decides whether this contactor keeps up with the cycle rate — not the AC-1 figure.
Auxiliary contact ratings cover 24 V at 10 A, 60 V at 2 A, 110 V at 1 A, 220 V at 0.3 A, 230 V at 6 A, and 400 V at 3 A — these are the values that matter for control-circuit coordination, not the main pole ratings.
Dimensions are 146 mm high by 70 mm wide by 139 mm deep. The S3 frame size is the physical envelope — it's the same footprint as other SIRIUS S3 contactors, so swapping between variants within the frame doesn't require re-drilling the panel or changing the DIN-rail layout. Solid wire capacity is 2x (0.25 to 2.5 mm²) for control wiring; stranded main power conductors accept 2x (10 to 50 mm²).
