SIRIUS 3RA2 direct starter — what ships in the box
The 3RA2115-0GA15-1AP6 is a Siemens SIRIUS 3RA2 non-fused motor starter, size S00, configured as a direct starter — meaning it ships as a factory-assembled unit combining a contactor and an overload relay in one package. It includes the contactor 3RT2015-1AP61, the circuit-breaker 3RV2011-0GA15, and the link module 3RA1921-1DA00 — three components that are mechanically and electrically coordinated at the factory to save panel wiring time.
Overload and short-circuit protection design
The overload release is thermal bimetallic — it tracks motor heating via current-squared-time and resets automatically after cooldown, no manual reset needed unless the application requires it. Short-circuit protection uses a magnetic trip element built into the supplied circuit-breaker 3RV2011-0GA15, giving instantaneous magnetic pickup on high fault currents. Rated insulation voltage is 690 V, with a surge voltage resistance of 6 kV — sufficient for 400/480 V industrial panels with standard overvoltage category III.
Mounting and panel fit
Mounting position is vertical only; clearance on the side is 9 mm, upwards 20 mm, downwards 10 mm — no clearance needed forward or backward. Operating temperature range is -20 to +60 °C, storage -50 to +80 °C, transport -55 to +80 °C — covers most indoor panel environments without derating.
