The coil connection uses screw-type terminals, which is the standard for panel wiring with ferruled or solid conductors. ## Switching Capacity and Duty Cycles For DC-13 duty (solenoid loads), the contactor is rated at 6 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. At 230 V AC, it is rated for 2 hp motor load. Switching frequency limits are 1000 cycles per hour for AC-1 (resistive), 750 per hour for AC-2 and AC-3 (motor start/run), and 250 per hour for AC-4 (plugging/inching). These duty-cycle figures govern the real-world thermal rise in the enclosure — a panel builder should derate if multiple contactors are ganged without spacing. The size S00 footprint is 45 mm wide, 58 mm high, and 117 mm deep — a compact profile that fits standard 600 mm deep enclosures with room for gland plates and wiring ducts. Main contacts accept solid or stranded conductors from 0.5 to 4 mm², or two conductors per terminal: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². The screw terminals are rated for the full current range of the size S00 frame. No auxiliary switch is integrated on this variant — if auxiliary contacts are needed for feedback or interlocking, a separate side-mount block must be added. The contactor is part of the SIRIUS family, which carries CE, UL, CSA, and other international approvals as standard for the series.","metaTitle":"Siemens 3RT2017-1BW44-3MA0 SIRIUS Power Contactor, 48 VDC Co","metaDescription":"Siemens SIRIUS 3RT2017-1BW44-3MA0 power contactor, size S00, 48 VDC coil, screw terminals, 45 mm width, active production.
