The coil termination uses screw-type terminals, a familiar interface for panel builders working with ferrule or ring lugs on the control circuit. An auxiliary switch is integrated on the contactor, providing a feedback or status signal without requiring a separate add-on block for basic applications. The S10 frame measures 210 mm high, 145 mm wide, and 202 mm deep — a substantial footprint that fits standard backpanel layouts but needs the depth verified against enclosure depth and gland-plate clearance. Mounting is via screw fixing through an 11 mm hole, with the contactor rotatable ±90° on a vertical surface and tiltable ±22.5° front-to-back, offering flexibility for tight cabinet arrangements. ## Power and Control Wiring Main power terminals accept stranded conductors from 70 to 240 mm² — sized for the high-current buswork this S10 contactor handles. Auxiliary and control wiring accepts solid conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or up to 2x (0.75 to 4 mm²) — covers standard control cable sizes for interposing relays and PLC outputs. ## Performance and Environmental Ratings Power factor at 50 Hz is 0.9, and at 60 Hz ranges from 0.8 to 1.1 — relevant when coordinating with power-factor correction or sizing upstream protection.","metaTitle":"Siemens 3RT1466-6AU36 SIRIUS Contactor, S10","metaDescription":"Siemens 3RT1466-6AU36 SIRIUS S10 contactor. 240-277V AC/DC coil, screw terminals, auxiliary switch included.
