What this SIRIUS direct starter delivers
The 3RA2110-0BA15-1BB4: Rated for 0.2 A at 400 V in AC-3 and AC-3e categories, the starter is built for small motor loads where the full-load current is well under 1 A — common on fractional-horsepower pumps, fans, and conveyor drives in automated warehouses or packaging lines. The 24 V DC coil (rated value 24...24 V) keeps control circuit wiring safe for PLC or safety relay outputs without an intermediate interface relay.
Protection and trip characteristics
The overload release is thermal bimetallic (ambient-compensated -20 to +60 °C), and the short-circuit trip is magnetic — a combined design that handles both sustained overloads and hard faults in one housing. Supplied as a factory-assembled set: contactor 3RT2015-1BB41 and link module 3RA1921-1DA00, so the coordination between the contactor and overload is pre-validated by Siemens — no guesswork on matching components.
Mounting and panel integration
Screw and snap-on mounting onto 35 mm DIN rail, vertical position only — the 45 mm width (size S00) fits standard 45 mm slot spacing in a control panel, leaving room for adjacent feeders or busbars. Dimensions: 97 mm deep, 45 mm wide, 167 mm tall. Clearance requirements: 50 mm upwards, 20 mm forwards, 10 mm downwards, 20 mm at the side — plan the enclosure depth and ventilation accordingly.
