Reversing starter, S0 frame, current production
The Siemens 3RA2225-4DB27-0AP6 is a non-fused reversing motor starter from the SIRIUS series, S0 size. It ships as a factory-assembled unit with the contactor 3RT2027-1AP60 and link module 3RA2921-1AA00 included.
Horsepower and current ratings across common voltages
At 400 V it delivers 11 000 W (approx 15 hp). Lower-voltage ratings include 7.5 hp at 220/230 V and 3 hp at 110/120 V.
Trip Class 10 and panel clearance dimensions
Mounts via snap-on fastening on a 35 mm standard DIN rail in vertical orientation. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, and 0 mm backwards — tight enough for dense panel layouts. Overall dimensions: 265 mm height, 90 mm width, 120 mm depth. Pollution degree 3 rating confirms suitability for industrial environments with conductive dust or occasional condensation.
Operating temperature and ambient limits
The wide transport range supports cold-chain or hot-warehouse logistics without special handling.
