Reversing starter for a motor control center slot
The 3RA2225-1FD24-0BB4 is a SIRIUS non-fused reversing motor starter — a single assembly that combines a reversing contactor pair, a thermal Class 10 overload relay, and the interlocking in one Size S0 footprint. It ships as a factory-assembled unit with the contactor (3RT2024-1BB40), link module (3RA2921-1BA00), and busbar adapter (8US1251-5NT10) included — no separate ordering or field wiring of the reversing interlock.
Busbar snap-on and panel clearances
Mounts by snapping onto 60 mm busbar systems — the fastening method is integral, no DIN rail adapter needed for the busbar mount. Dimensions: 165 mm deep, 90 mm wide, 260 mm high. Required clearances around the unit: 30 mm upward, 10 mm forward, 10 mm downward, 9 mm at the side, and 0 mm backward — the back face sits flush against the mounting surface. Mounting position is vertical only; operating temperature range is -20 to +60 °C, with storage from -50 to +80 °C.
Current production — sourcing posture
RoHS compliance date is March 1, 2017 — the starter meets the EU RoHS substance restrictions as of that date.
