The Siemens 3RA2110-0KA15-1BB4 is a SIRIUS direct-on-line starter in Size S00, combining a contactor and a thermal bimetallic overload relay in one package. Rated AC-3 at 1.25 A at 400 V, it's sized for small motor loads like pumps or fans on a DIN-rail panel.
Clearance needs: 50 mm above, 20 mm front, 20 mm sides, 10 mm below — zero clearance behind.
The supplied contactor is 3RT2015-1BB41, so if you're swapping just the contactor in a panel, that's the specific sub-unit.
The starter is rated AC-3 at 1.25 A at 400 V, with a 24 V DC coil and Class 10 thermal overload protection. Motor power rating is 370 kW at 400 V.
Width is 45 mm, depth 97 mm, height 167 mm. Mounts on 35 mm DIN rail with 50 mm clearance above, 20 mm front and sides, 10 mm below, zero behind.
