The 3RA2225-1GB24-0AK6 is a non-fused reversing motor starter from the Siemens SIRIUS family, Size S0. This means it integrates two contactors and a link module in a single assembly to reverse a three-phase motor without external interlocking wiring. The AC-3 rated voltage is 690 V maximum, so it is suitable for 400 V and 480 V line supplies common in European and North American industrial panels. At 400 V, the rated power is 2 200 W. These figures define the maximum motor frame size this starter can handle in continuous duty.
Panel integration — DIN rail footprint and clearances
Mounting is snap-on fastening on a 35 mm standard rail, per EN 60715. The mounting position is vertical, which is the standard orientation for heat dissipation in a closed panel. The physical envelope is 120 mm depth, 90 mm width, and 265 mm height. For panel layout, the required clearances are: 30 mm upwards, 10 mm forwards, 10 mm downwards, and 9 mm at the side. Backwards clearance is 0 mm, meaning the unit can sit flush against a backplate. The supplied contactor is 3RT2024-1AK60 and the supplied link module is 3RA2921-1AA00. These are the specific components within the assembly, which matters for BOM traceability and spare parts ordering.
No stock-holding claim is made; each order is quoted individually. For compliance documentation, the substance prohibitance date is 03/01/2017, which aligns with RoHS and REACH requirements. The degree of pollution is 3, per IEC 60947-1, meaning it is rated for conductive pollution environments typical in industrial control panels.
