Main circuit connections use spring-loaded terminals accepting 2x (0.25 to 2.5 mm²) solid or stranded copper, which speeds wiring and holds under vibration better than screw terminals. Rated for AC-3 motor switching at 5.5 kW on 400 V three-phase, this contactor handles the inductive inrush of standard squirrel-cage motors up to that power — the rating that governs real motor starts, not the resistive AC-1 figure. For reversing or plugging duty (AC-4), it carries 8.5 A at 400 V, so expect reduced service life if used for frequent inching or jogging of a motor near its full AC-3 rating. Motor power ratings extend to 5.5 kW at both 500 V and 690 V, making it suitable for 690 V line supplies common in wind turbine nacelles or mining installations. Coil hold power is a constant 3.3 W DC, so the thermal load on the panel stays low even under continuous energization. ## Environmental and installation limits Front face is IP20, meaning finger-safe when installed in a closed panel; the terminals themselves are also IP20, so no additional shrouding is required for basic touch protection. ## Protection coordination and sourcing posture","metaTitle":"Siemens 3RT1017-2BP41 SIRIUS S00 Contactor, 5.5 kW at 400V","metaDescription":"Siemens SIRIUS 3RT1017-2BP41 power contactor, size S00, 5.5 kW at 400V AC-3.

The 3RT2024-2BB40 is a larger-frame S2 contactor that physically will not fit the same DIN rail footprint without re-termination. For a drop-in equivalent, stick with the same size S00 frame and verify the coil voltage matches."},{"question":"What are the physical dimensions of this contactor?","answer":"It measures 45 mm wide, 60 mm high, and 73 mm deep — the 45 mm width is the key dimension for rail spacing in a multi-contactor assembly."},{"question":"What wire sizes does the spring-loaded terminal accept?","answer":"The main circuit terminals accept 2x (0.25 to 2.5 mm²) solid or stranded copper, or 2x (24 to 14 AWG). No ferrule is required for stranded wire, but ferrules improve pull-out force in high-vibration environments."},{"question":"Will this contactor drop into a panel designed for a 3RT1015-1BB42?","answer":"It shares the same S00 frame size and DIN rail mounting, so the physical footprint and rail clip are identical. However, the 3RT1017-2BP41 has a higher AC-3 rating (5.5 kW vs the 3RT1015's lower rating), so the upstream protection and cable sizing must be checked before substitution."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1017-2BP41","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/3RT1017-2BP41 when reusing this data.
