The power circuit accepts stranded conductors from 70 to 240 mm², sized for high-current motor or resistive loads in a 214 mm high by 160 mm wide by 225 mm deep envelope. Mounting is screw-fixed with a vertical mounting surface; the unit can be rotated ±90° or tilted ±22.5° forward and back, giving panel builders flexibility in tight enclosures. An auxiliary switch is included as standard, with contact ratings that span the control voltage range: 10 A at 24 V, 6 A at 230 V, tapering to 0.3 A at 220 V DC — check your specific pilot duty against the curve. The magnet coil operates on AC or DC from 110 to 127 V, with a pickup threshold of 0.8 × rated value and a dropout floor at 0.1 × rated value. Pull-in and dropout times are 60–100 ms for both AC and DC supplies, and arcing time sits at 10–15 ms — predictable switching behavior for sequencing logic. The coil suppression is internal; no external free-wheel diode is required for DC operation. Screw fixing through a single 11 mm hole secures the contactor to the backplate. Up to four auxiliary contact blocks can be attached to the front, expanding the control interface without increasing the footprint. The S12 frame size is a common Siemens platform; spare parts and replacement coils are widely cross-referenced.","metaTitle":"Siemens 3RT1476-6AF36-0KU0 SIRIUS Contactor, Size S12, 110-1","metaDescription":"Siemens SIRIUS 3RT1476-6AF36-0KU0 contactor, Size S12 frame. 110-127 V AC/DC coil, screw terminals.
