Part Identity and Key Ratings
The Siemens SIRIUS 3RT1466-6PF35 is a Size S10 contactor with a 96-127 V AC/DC coil, terminated via screw-type terminals on the magnet coil. It is listed in a current production lifecycle stage, meaning it remains an active, factory-order line item — not a phase-out or NRND part.
What the Ratings Mean for Fit
The Size S10 frame (210 mm high, 165 mm wide, 202 mm deep) is a large industrial contactor class. The 96-127 V AC/DC coil covers both common control voltages in a single device — no need to select a separate AC or DC variant for that range. Screw-type coil terminals are the standard for high-current power connections, not spring-cage; expect to land lugs or ring terminals on the main power circuit. The auxiliary contact ratings are specified per DC voltage level: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, and 0.3 A at 220 V. These are the make/break capacities for DC control circuits — a 24 V PLC output driving this coil sees a 10 A contact rating, which is generous for a signal-level load but reflects the contactor's industrial rating method. At 230 V AC the auxiliary is rated 6 A. Mechanical life is rated at 10,000,000 operations typical. Arcing time is 10-15 ms. The mounting position allows vertical surface installation with ±90° rotation and ±22.5° tilt front-to-back, giving panel layout flexibility. Operating temperature range is -25 to +60 °C.
