It is designed for snapping onto 60 mm busbar systems in a vertical mounting position, which keeps the panel layout compact and the busbar connections clean. The CLASS 10 trip class means it protects motors with short acceleration times — typical for pumps, fans, and light conveyors — without nuisance tripping on start-up. ## Thermal overload — no electronics to fail The overload release is thermal bimetallic, so there is no electronic adjustment or microprocessor to drift. Ambient compensation is built into the bimetal curve; the operating range is -20 to +60 °C. If the motor FLA changes, you swap the heater element or the entire starter — not a parameter. The supplied contactor is 3RT2023-1AK60, a known service part. If the starter fails in the field, the contactor alone can be replaced without pulling the entire busbar adapter or link module. ## Panel fit and clearances Dimensions: 155 mm deep, 90 mm wide, 260 mm tall. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, and 0 mm backwards. The zero backward clearance means it can sit flush against a back panel or busbar support — useful when depth is tight. The supplied busbar adapter is 8US1251-5NT10, and the link module is 3RA2921-1AA00. Both are standard SIRIUS accessories, so replacement or expansion parts are readily available through distribution. ## Compliance and documentation The substance prohibitance date is 03/01/2017, aligning with RoHS and REACH compliance milestones. The degree of pollution is 3, meaning it is rated for conductive pollution environments — typical in industrial enclosures without climate control. The product brand is SIRIUS, Siemens' standard motor management platform. No UL or CSA listing is stated in the spec record, but the 690 V AC-3 rating and pollution degree 3 indicate IEC 60947-4-1 design. Confirm local code acceptance with the project engineer.","metaTitle":"Siemens 3RA2225-1AD23-0AK6 SIRIUS reversing starter","metaDescription":"Siemens 3RA2225-1AD23-0AK6 SIRIUS reversing motor starter, non-fused, size S0, CLASS 10 thermal overload, 690 V max.
