The 3RA2210-1DA15-2BB4: For high-inertia loads that need a longer acceleration ramp, Class 10 may trip prematurely; that is a selection gate to check before committing the BOM line. The supplied contactor is 3RT2015-1BB42, and the supplied link module is 3RA1921-1DA00 — the reversing starter ships as a pre-assembled unit with the mechanical interlock and wiring between the two contactors already in place. Screw-type terminals on the main current circuit mean the installer lands ring or fork lugs; no special crimp tooling required.
Panel integration — DIN rail footprint and clearance zones
The dimensions are 170 mm height, 90 mm width, 97 mm depth — the depth is the projection from the DIN rail face to the front of the terminals, which governs the enclosure depth needed. Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, 10 mm at the side, 0 mm backwards. The backwards clearance of zero means the unit can sit flush against the back panel or a busbar support — useful when packing multiple feeders into a shallow enclosure. Forwards clearance of 32 mm is the space needed for the screwdriver swing on the terminals.
