12 A AC-3 reversing starter on 60 mm busbars
The 3RA2210-1KD17-2BB4: Designed for snapping onto 60 mm busbar systems — the mounting footprint is vertical only, with 155 mm depth, 90 mm width, and 204 mm height.
Supplied components and wiring terminals
This reversing starter ships with the 3RT2017-1BB42 contactor and the 3RA1921-1DA00 link module — the contactor is pre-wired to the reversing interlock, so field wiring is limited to the main circuit and control voltage. Main current circuit connections use screw-type terminals, which are standard for panel builds and accept up to the wire sizes matching the S00 frame rating. The control supply is rated 24 V DC, with the coil draw determined by the 3RT2017 contactor — confirm the PLC output or relay can sink the inrush before committing the BOM.
Clearance and ambient limits
Minimum clearances around the unit: 50 mm upwards, 32 mm forwards, 10 mm downwards, and 10 mm at the side — no clearance needed at the back since it mounts directly on the busbar. Operating ambient temperature range is -20 to +60 °C, with storage and transport limits from -50 to +80 °C — the temperature compensation is active across the full operating band.
