The Siemens 3RA2215-0GD15-2AK6 is a SIRIUS non-fused reversing motor starter in size S00, designed as a complete, pre-assembled unit for reversing motor control in a single enclosure footprint. It integrates a supplied contactor (3RT2015-1AK62), a supplied circuit-breaker (3RV2011-0GA15), a link module (3RA1921-1DA00), a busbar adapter (8US1251-5DS10), and an RS assembly kit (3RA2913-1DB1) — everything needed for a reversing starter in one order code. The overload release is thermal (bimetallic) with a Trip Class 10 characteristic, and the short-circuit trip is magnetic — so it provides both overload and short-circuit protection for the motor branch circuit.
The unit fastens by snapping onto 60 mm busbar systems, which is the standard panel-building method for SIRIUS feeders in a distribution board or motor control centre. Mounting position is vertical; the dimensions are 200 mm height, 90 mm width, and 155.1 mm depth — size S00 is the most compact SIRIUS feeder frame, saving panel space when multiple reversing starters are ganged. Main contact wiring accepts stranded conductors 0.5 to 4 mm² (single) or 2x 0.75 to 2.5 mm²; AWG equivalents are 2x 20–16 (contactor only), 2x 18–14, and 2x 12.
Operating temperature range is -20 to +60 °C; storage from -50 to +80 °C; transport from -55 to +80 °C. Pollution degree 3 (industrial environment with conductive or dry non-conductive pollution).
