It mounts via screw and snap-on onto 35 mm DIN rail per EN 50022, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when panel layout forces an unconventional orientation. ## Motor Power Ratings & Duty Cycles For motor switching, the 3RT6017-1KB42 delivers 7.5 kW at 230 V, 13 kW at 400 V, and 22 kW at 690 V (all at 60 °C ambient). The AC-3 maximum switching rate is 750 1/h, and AC-4 (plugging/reversing) drops to 250 1/h — that's the limit for high-duty-cycle applications like reversing conveyors or crane motions. The insulation voltage is rated 690 V, and the AC-3 maximum operating voltage matches at 690 V, so it's suitable for 400 V and 690 V line-fed motors within the power envelope. ## Coil Suppression & Wiring The surge suppressor is a built-in diode, so the coil is polarity-sensitive — verify +24 VDC to the correct terminal before energizing. Main circuit terminals accept 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), or 2x 4 mm² solid/stranded; AWG equivalents are 2x (20–16), 2x (18–14), or 2x 12. At 40 °C the minimum permissible conductor is 4 mm²; at 60 °C it's 2.5 mm² — derate the wire if the panel ambient runs hot.","metaTitle":"Siemens 3RT6017-1KB42 SIRIUS Coupling Contactor, 24 VDC Coil","metaDescription":"Siemens 3RT6017-1KB42 SIRIUS coupling contactor, size S00, 24 VDC coil rated 6 A, screw terminals, DIN rail mount.

The difference is the coil voltage — 3RT6017-1KB42 has a 24 VDC coil rated 6 A, while 3RT6017-1KF42 uses a different coil voltage. If the control circuit is already 24 VDC, it drops in without rewiring; if the panel was wired for a different coil voltage, you'd need to change the control supply."},{"question":"What compliance documentation does Siemens provide for 3RT6017-1KB42?","answer":"The part carries a substance prohibition date of 05/01/2012, indicating RoHS compliance. As a SIRIUS product, it is designed to meet IEC/EN 60947-4-1 standards for contactors. UL and CSA approvals are typical for this series, though specific certification marks should be verified from the product label or declaration of conformity."},{"question":"What is 3RT6017-1KB42's depth and width?","answer":"Depth is 73 mm, width is 45 mm, and height is 57.5 mm — size S00 footprint."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT6017-1KB42","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/3RT6017-1KB42 when reusing this data.
