What this reversing starter delivers
The 3RA2225-4AB26-0BB4 is a SIRIUS non-fused reversing motor starter in size S0 — a factory-assembled combination of a contactor pair, a thermal overload relay, and a mechanical interlock, all on a common snap-on base for 35 mm DIN rail. The 24 V DC coil is supplied via the integrated link module (3RA2921-1BA00); the busbar adapter (3RA2922-1AA00) and the contactor (3RT2026-1BB40) are included as part of the assembly. This is a drop-in reversing solution — no separate interlock wiring or overload selection needed.
Mounting and panel integration
Snap-on fastening to 35 mm standard rail, vertical mounting position only. Dimensions: 90 mm wide, 130 mm deep, 265 mm tall. Clearance requirements: 30 mm upwards, 10 mm forwards, 10 mm downwards, 9 mm at the side, 0 mm backwards — the back of the unit sits flush against the mounting surface. The S0 frame size keeps the footprint compact for a reversing starter — expect it to occupy roughly the space of two S0 contactors side by side.
