The Siemens 3RK1315-6KS71-1AA0 is a SIRIUS reversing motor starter rated for 0.75 kW at 400 V (0.7 hp at 460/480 V) with Trip Class 10 protection. It's built for reversing applications — forward/reverse control of a motor without external contactors. The IP65 enclosure means it handles washdown environments, so it's a fit for food processing or outdoor conveyor lines where dust and hose-down are daily.
This starter is a reversing design, not a direct-start unit — it integrates two contactors in one housing for forward/reverse motor control. It communicates via AS-Interface, not PROFIBUS or PROFINET, so it's suited for AS-i networks common in material handling and assembly lines. The 4 digital inputs and 1 digital output handle local sensors and feedback without an extra I/O block.
Mounts via screw fixing in vertical, horizontal, or flat orientation — the recommended position is horizontal. Dimensions are 294 mm wide, 215 mm high, 159 mm deep, so it needs a decent footprint in the panel. Power connections use a HAN Q4/2 plug per ISO 23570; the AS-Interface addressing is through an M12 plug. Supply voltage is 24 V DC (20.4 to 28.8 V range, max 31.6 V).
