AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. The 72 mm depth leaves clearance for wiring ducts and adjacent components on the DIN rail. The 6 mm spacing at the side is the minimum air gap to adjacent live parts — maintain that for creepage and clearance at pollution degree 3. This matters when coordinating with motor branch circuit protection — match the fuse class and rating to the coordination type your panel design specifies. ## Operating conditions and ratings The coil pick-up voltage is 0.85 x rated (93.5 V DC minimum), and the full-scale drop-out is 1.1 x rated (121 V DC), so the contactor holds in during dips but drops out reliably on undervoltage. Auxiliary switching capacity at 24 V DC is 10 A, at 110 V DC is 1 A, and at 220 V DC is 0.3 A — typical for DC load breaking where arc extinction is slower than AC.","metaTitle":"Siemens 3RT1317-1FF40 SIRIUS Power Contactor, 110 V DC Coil,","metaDescription":"Siemens SIRIUS 3RT1317-1FF40 power contactor, size S00, 110 V DC coil, 4 NO main contacts, 5.5 kW at AC-2 400 V.
