The coil is 110 V DC; verify control voltage matches before wiring. Both the main current circuit and the magnet coil use spring-loaded (spring-type) terminals, accepting 2x (0.5... 2.5 mm²) solid or stranded — no screw torque to check, but strip length matters for a clean insertion. Dimensions are 45 mm wide, 70 mm high, 73 mm deep, so it occupies a single 45 mm module on the rail; side-by-side mounting is permitted with a 6 mm gap at the side for airflow and arc clearance. ## Electrical Ratings and Duty Rated for AC-3 at 400 V at 12 A and 5.5 kW; in AC-4 (reversing/inching duty) at 400 V it handles 4 kW — the AC-4 figure matters if the contactor sees frequent plugging or jogging.","metaTitle":"Siemens 3RT2317-2BF40 SIRIUS Contactor, 12 A / 5.5 kW at 400","metaDescription":"Siemens SIRIUS 3RT2317-2BF40 contactor, size S00, 12 A / 5.5 kW at 400 V AC-3, 110 V DC coil, spring-loaded terminals.
