The evidence does not list UL, CSA, or CE marks explicitly, but the SIRIUS series typically carries these for the European and North American markets — verify with the full datasheet for your jurisdiction."},{"question":"What are the key electrical ratings for fit?","answer":"45 kW at 400 V AC-2 (slip-ring motor duty), 80 A at 400 V AC-4 (reversing/inching), 55 kW at 500 V, and 25.4 kW at 690 V. The AC-2 figure is the one that decides fit for most motor applications."},{"question":"How does this compare to the 3RT1044-1FB46?","answer":"The 3RT1044-1FB46 is a smaller S2-frame contactor with lower current ratings. The 3RT1046-3AP00 (S3 frame) carries higher AC-2 power (45 kW vs lower) and larger terminal capacity (2x 10–50 mm² stranded). They are not drop-in replacements — the S3 frame is physically larger and requires more DIN-rail space. If your panel was designed around the S2 frame, you would need to verify mounting footprint and busbar spacing before substituting."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT1046-3AP00","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/3RT1046-3AP00 when reusing this data.
