The Size S10 designation tells you the physical envelope and the maximum thermal continuous current the contactor can handle; it governs the main power lug capacity, which on this unit accepts stranded conductors from 70 mm² up to 240 mm², so it is built for feeders and large motor branch circuits, not small panel auxiliaries. Mounting is screw fixing with a vertical mounting surface — the contactor can be rotated ±90° and tilted ±22.5° front-to-back, which gives flexibility in tight enclosures or when aligning with busbar systems. The 210 mm height, 145 mm width, and 202 mm depth mean it occupies a full-size footprint; plan for a 10 mm clearance above and below and 20 mm forward clearance for arc-chamber venting (arcing time is 10-15 ms). The coil is rated 42-48 V AC/DC with pickup at 80% of rated value and dropout below the hold threshold — operate time is 40-80 ms on both AC and DC, consistent for sequencing interlocking. ## Coil and auxiliary circuit — what the 42-48 V AC/DC rating drives The coil is screw-type terminals, accepting solid or stranded wire: 2x 0.5-1.5 mm², 2x 0.75-2.5 mm², or max 2x 0.75-4 mm². That is a standard control-circuit termination — compatible with most PLC digital outputs and relay interposing panels. The 42-48 V AC/DC coil voltage is common in industrial control systems using 48 V DC control buses or 42 V AC derived from control transformers; verify your control supply matches before wiring. The contactor ships with an auxiliary switch block (4 contacts attachable). The auxiliary contacts are rated: 10 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 6 A at 230 V — the ratings drop with voltage due to arc extinction limits. For a 24 V DC PLC input circuit, the 10 A rating gives generous headroom for multiple feedback signals.","metaTitle":"Siemens 3RT1466-6AD36 SIRIUS Contactor, Size S10, 42-48 V AC","metaDescription":"Siemens 3RT1466-6AD36 SIRIUS Size S10 contactor. 42-48 V AC/DC coil, 70-240 mm² power wiring, screw fixing.
