The 110 V DC coil with screw-type terminals pulls in at 0.8 x rated voltage and drops out at 1.1 x rated, giving a clean operate band for DC control circuits. Mechanical life is rated at 30 million operations, with arcing time between 10 and 15 ms and DC operate time of 7 to 13 ms — figures that matter when coordinating contactor timing in a motor starter sequence. ## Panel Integration — DIN Rail Mounting and Clearances The 45 mm width, 58 mm height, and 73 mm depth fit standard S00 panel layouts. Main current circuit and magnet coil both use screw-type terminals. Solid conductors accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²); stranded accepts 0.5 to 4 mm². Auxiliary contacts share the same 20–12 AWG range. Two attachable auxiliary switch blocks are supported.","metaTitle":"Siemens 3RT2317-1BF40 SIRIUS Contactor, 5.5 kW AC-3, 110 V D","metaDescription":"Siemens SIRIUS 3RT2317-1BF40 contactor, Size S00, 5.5 kW at 400 V AC-3, 12 A AC-1, 110 V DC coil.
