The coil is rated 175-280 V AC, drawing 2.4 VA at both 50 Hz and 60 Hz, with a 43 A inrush peak. Rated operational current at 24 V DC is 10 A, dropping to 2 A at 48 V and 60 V DC, which sets the auxiliary contact capacity for DC control circuits. ## Switching Duty and Mechanical Endurance Maximum switching frequency varies by duty class: 900 cycles/hour at AC-1 (resistive), 850 cycles/hour at AC-3 and AC-3e (squirrel-cage motor starting), 350 cycles/hour at AC-2 (slip-ring motor), and 250 cycles/hour at AC-4 (plugging/inching). The specified arcing time of 10-20 ms and operate times of 38-57 ms (both AC and DC) define the contact timing window for coordination with upstream protection. Mechanical endurance is rated at 5,000,000 operating cycles typical, with an MTBF of 52 a, supporting long-service applications in continuous-process lines where contactor replacement triggers a requalification event. ## Panel Integration and Clearance Requirements Mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving flexibility in crowded enclosures. Required clearances: 10 mm upwards, 10 mm downwards, 10 mm at the side, 20 mm forwards. Dimensions are 70 mm wide, 152 mm deep, and 140 mm high. Main circuit wiring accepts solid conductors 2.5-16 mm² or stranded 6-70 mm²; auxiliary wiring accepts 2x (0.5-1.5 mm²) or 2x (0.75-2.5 mm²) solid or stranded. Screw-type terminals on the magnet coil. ## Environmental and Lifecycle Status For BOM planning, the 52 a MTBF figure supports a preventive replacement interval aligned with the plant's major shutdown cycle rather than calendar-based swap-out.","metaTitle":"Siemens 3RT2046-1SP30 SIRIUS Power Contactor, S3","metaDescription":"Siemens 3RT2046-1SP30 SIRIUS power contactor, size S3, 175-280 V AC coil, screw terminals.
