The 24 VDC coil draws 3.3 W holding power, with a pickup threshold of 0.85 x rated voltage and a dropout below the 1.1 x full-scale ceiling — a standard DC solenoid curve that panel builders can budget without surprises. AC-4 at 400 V is rated 6.5 A — that covers plugging or inching duty on squirrel-cage motors, where the contactor sees the locked-rotor current each cycle. For resistive loads (AC-12), the maximum operating current is 10 A. Type 1 coordination allows up to 35 A. Pollution degree 3 (conductive pollution) means the contactor is suited for industrial environments where temporary condensation or light dust is expected — no additional conformal coating needed for standard panel conditions. The IP20 rating on the front and terminals means the contactor is touch-safe for panel interiors but not washdown-rated; keep it behind an enclosure door in wet areas. ## Panel Fit and Wiring — S00 Footprint, Spring-Cage Terminals The spring-loaded terminal accepts 2x (0.25 to 2.5 mm²) or 2x (24 to 14 AWG). Side-by-side mounting is permitted, which simplifies multi-contactor assemblies for star-delta or reversing starters. ## Sourcing and Lifecycle — Active Part, Quoted to Order","metaTitle":"Siemens 3RT1015-2BW41 SIRIUS Power Contactor, S00, 24 VDC Co","metaDescription":"Siemens SIRIUS 3RT1015-2BW41 power contactor, Size S00, 24 VDC coil, spring-loaded terminals, IP20, active production.

Both share the same S00 frame size, 45 mm width, and DIN-rail mounting pattern, so the mechanical fit is identical. The wiring difference is the terminal type — spring-cage vs. screw clamp — so the panel layout and wire routing are compatible, but the termination method changes."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1015-2BW41","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/3RT1015-2BW41 when reusing this data.
