SIRIUS 3RA2 reversing starter — form factor and supplied components
The Siemens 3RA2225-0HB23-0BB4 is a SIRIUS 3RA2 non-fused reversing motor starter, size S0, designed for snap-on fastening on a 35 mm standard rail in vertical mounting position. It ships as a factory-assembled unit including the contactor 3RT2023-1BB40, circuit-breaker 3RV2011-0HA15, link module 3RA2921-1BA00, busbar adapter 3RA2922-1AA00, and RH assembly kit 3RA2923-1BB1 — the reversing pair, overload relay, and short-circuit protection come pre-integrated. Dimensions are 130 mm depth by 90 mm width, 265 mm tall, with clearance requirements of 30 mm upwards, 10 mm forwards, 10 mm downwards, and 9 mm at the side.
Motor ratings and trip characteristics
Trip class is CLASS 10, meaning the bimetallic overload release will trip within 10 seconds under a 7.2× cold start — standard for standard-duty motor starting where the acceleration time stays under 10 seconds. The short-circuit trip is magnetic, and the overload design is thermal bimetallic — no electronic adjustment, so the trip curve is fixed per the CLASS 10 characteristic.
Environmental and supply specs
Operating temperature range is -20 to +60 °C; storage range is -50 to +80 °C; transport range is -55 to +80 °C — the starter can sit in an unheated warehouse or ship in winter without derating. Degree of pollution is 3, meaning it tolerates conductive pollution in industrial control panels where condensation may occur. Substance prohibitance date is 03/01/2017 — the part complies with RoHS/REACH restrictions in effect as of that date.
