The supplied contactor is a 3RT2027-1AK60; the link module is 3RA2921-1AA00. The circuit-breaker size matches S0. This is a complete reversing starter package — wire it in and commission. ## Clearance and panel fit Snap-on fastening on 35 mm DIN rail, vertical mounting only. Required clearances: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, 0 mm backwards. That 0 mm backwards means it can sit flush against the back panel — useful when gland-plate depth is tight. Operating temperature range -20 to +60 °C; storage -50 to +80 °C; transport -55 to +80 °C. Rated insulation voltage 690 V. AC-3 rated maximum voltage 690 V.","metaTitle":"Siemens 3RA2225-4CB27-0AK6 SIRIUS Reversing Starter","metaDescription":"Siemens SIRIUS 3RA2225-4CB27-0AK6 non-fused reversing motor starter, 11 kW at 400 V AC-3, Trip Class 10, snap-on 35 mm DIN rail.

The 3RA2225-4CB27-0AK6 is a complete reversing starter assembly with contactor and overload relay; the 3RV2023-4CA10 would require separate contactors and a reversing contactor assembly to match function. They share the S0 frame size and DIN-rail footprint, so a panel designed for the 3RV2023-4CA10 could physically accept the 3RA2225-4CB27-0AK6, but wiring and control logic differ."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RA2225-4CB27-0AK6","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/3RA2225-4CB27-0AK6 when reusing this data.
