The main contact block is 4 NO (four normally open), with zero NC main contacts, so the part is suited for applications needing multiple independent load circuits switched on together. The auxiliary contacts are rated for 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V, and 6 A at 230 V — these are the switching capacities for control circuits at different voltage levels. The enclosure is rated IP20 on the front and at the terminals, meaning finger-safe but not protected against moisture — suitable for dry indoor panel environments. The 3RT1317-1BA40 uses screw-type terminals for the main current circuit, accepting solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²). AWG equivalents are 2x (20 to 16), 2x (18 to 14), and 1x 12. Dimensions are 45 mm wide, 57.5 mm high, and 72 mm deep — a compact footprint that fits standard 45 mm DIN-rail slots.","metaTitle":"Siemens SIRIUS 3RT1317-1BA40 Power Contactor, Size S00, 4 NO","metaDescription":"Siemens SIRIUS 3RT1317-1BA40 power contactor, size S00, 4 NO main contacts, 5.5 kW at AC-2 400 V.

The 3RT1317-1BA40 also uses screw terminals versus the 3RT1015-1BB42's spring-cage terminals, so a panel swap would require verifying the terminal type and the motor load rating."},{"question":"What is the depth of the 3RT1317-1BA40?","answer":"The depth is 72 mm."},{"question":"What conductor sizes does the 3RT1317-1BA40 accept?","answer":"The screw terminals accept solid or stranded conductors: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), and up to 2x (0.75 to 4 mm²).

However, the 3RT1317-1BA40 uses screw terminals while the 3RT1015-1BB42 uses spring-cage terminals, so the wiring method differs. Also verify the motor load rating: the 3RT1317-1BA40 is rated for 5.5 kW at AC-2, while the 3RT1015-1BB42 is rated for 4 kW at AC-3 — the application duty class and power level must match."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1317-1BA40","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT1317-1BA40 when reusing this data.
