It ships with the contactor 3RT2026-1AK60 and the link module 3RA2921-1AA00 already integrated, so you mount and wire one unit instead of piecing together separate contactors and an overload. ## Duty ratings and motor sizing At 460/480 V it delivers 10 hp; at 575/600 V it still holds 10 hp, so it covers North American 480Y/277 V and 600 V systems without derating. The AC-3 maximum voltage is 690 V, meaning it can switch motors on 690 V delta-connected windings (common in European heavy industry) as long as the current stays within the contactor's rating. ## Mounting and panel fit Snaps onto a 35 mm standard DIN rail — no screws needed for the rail mount. Mounting position is vertical only, so plan the panel layout with the starter oriented upright. Physical envelope: 90 mm wide, 120 mm deep, 265 mm tall. The S0 size keeps it compact enough for a 600 mm wide panel section, but the 265 mm height may conflict with shallow enclosures — check the backpan clearance. Clearance requirements: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the side, and 0 mm backward. The zero backward clearance means it can sit flush against the backpan, but the 10 mm forward space is needed for the contactor arc chamber venting. ## Environmental limits and compliance Storage range is -50 to +80 °C; transport range is -55 to +80 °C. Pollution degree 3 rating means it's suitable for industrial environments with conductive dust or occasional condensation — typical for motor control centers in process plants. RoHS compliance dated March 1, 2017 — the starter meets the EU substance restrictions effective from that date. No REACH or UL marking is explicitly listed in the spec record, so verify with the full datasheet if those are contract requirements.","metaTitle":"Siemens 3RA2225-4AB26-0AK6 SIRIUS Reversing Starter","metaDescription":"Siemens SIRIUS 3RA2225-4AB26-0AK6 reversing motor starter, size S0, Class 10, 7.5 kW at 400 V AC-3.
