SIRIUS Size S00 Power Contactor — 3RT1017-1AD01-1AA0
It carries a 10 A rated operational current at 24 V DC and 5.5 kW at 400 V in AC-3 duty, making it suited for small-to-medium induction motors on conveyors, pumps, and fans. The 45 mm wide body snaps onto a 35 mm DIN rail per EN 50022, and the screw-type terminals accept conductors from 0.5 to 4 mm².
The AC-3 rating at 400 V (5.5 kW) is the figure that governs motor switching — it tells you this contactor can handle a standard 5.5 kW induction motor across the line. The AC-1 resistive rating at 400 V (3 A) covers heater or lighting loads where inrush is minimal. For DC switching, the 24 V DC rating of 10 A drops to 0.3 A at 220 V DC due to arc extinction limits in DC circuits — factor that into any DC load schedule. Pollution degree 3 (industrial environment with conductive or dry non-conductive pollution) and a -25 to +60 °C operating range mean this contactor is rated for unheated enclosures and typical factory-floor conditions. The mechanical endurance of 30 million operations exceeds the electrical endurance by a wide margin — in practice, the electrical life under load (not stated here) will be lower, but the mechanical figure confirms the contactor is built for high-cycle applications like packaging or material handling where the coil cycles frequently.
The 72 mm depth leaves clearance for wiring ducts and busbar systems. The screw-type terminals accept 2 x (0.5 to 1.5 mm²), 2 x (0.75 to 2.5 mm²), or up to 2 x (0.75 to 4 mm²) — the larger cross-section is for power-in and power-out, while the smaller range suits control wiring. AWG equivalents are 2 x (20 to 16), 2 x (18 to 14), and 1 x 12. The 6 mm side clearance to adjacent components is the minimum for heat dissipation; no additional gap is required when using the side-by-side mounting feature.
