Reversing starter for compact motor control
The Siemens 3RA2210-1AA15-2BB4 is a SIRIUS reversing starter in the size S00 frame — a pre-assembled combination of a contactor pair and overload relay that handles forward/reverse motor control in a single DIN-rail footprint.
Panel fit and mounting constraints
Clearance requirements: 50 mm upwards, 32 mm forwards, 10 mm downwards, and 10 mm at the side for airflow and wiring access — zero clearance needed backwards. Main circuit connections use screw-type terminals — no special tooling needed, but torque the terminals to the values in the product drawing for the 1.6 A rating to hold.
Built-in components and serviceability
The reversing starter ships with a 3RT2015-1BB42 contactor and a 3RA1921-1DA00 link module pre-assembled — if either component fails in the field, those order codes are the direct replacement parts. Rated for operation from -20 to +60 °C ambient, with storage and transport tolerance from -50 to +80 °C — suitable for unheated enclosures in most industrial environments. The coil is 24 V DC — confirm your control transformer or power supply matches before wiring; the 24 V DC coil draws less inrush than an AC coil of the same rating, which simplifies PLC output sizing.
