Size S0 reversing starter — 690 V AC-3, Class 10 trip
The 3RA2225-1DB23-0AP6 is a Siemens SIRIUS non-fused reversing motor starter, size S0, rated for AC-3 duty up to 690 V. It ships as a factory-assembled unit with the 3RT2023-1AP60 contactor and 3RA2921-1AA00 link module — no separate wiring of the reversing interlock needed.
Horsepower and current coverage across common line voltages
At 400 V it is rated 1 100 W, and at 500 V it is rated 1 500 W for European 50 Hz installations. Current ratings at 480 V are 2.8 A, and at 600 V are 3.16 A — the starter is sized for fractional to small integral-horsepower reversing applications where space on the DIN rail is tight.
Snap-on DIN rail mounting with clearance zones
Snaps onto a 35 mm standard rail (EN 60715) in vertical mounting position. The envelope is 90 mm wide, 120 mm deep, and 265 mm tall — plan for 30 mm clearance above, 10 mm in front, 10 mm below, and 9 mm to the side for airflow and wiring access. Pollution degree 3 rating means it is suitable for industrial control panels where conductive dust or occasional condensation is present — no conformal coating required in a standard IP54 enclosure.
