Control power is 24 V DC (20.4 to 28.8 V range, max 31.6 V), and the unit communicates over AS-Interface for start/stop commands and diagnostics — no PROFIBUS or PROFINET onboard, so plan the fieldbus gateway accordingly. Four digital inputs are available for local sensors or limit switches, addressed via an M12 plug; the main circuit connects through a HAN Q4/2 connector per ISO 23570. ## Mounting and environment — panel integration notes Mounts by screw fixing in vertical, horizontal, or flat orientation — the recommended position is horizontal for optimal heat dissipation from the Trip Class 10 bimetal relay. Dimensions are 294 mm wide by 215 mm high by 159 mm deep — this is a standalone enclosure, not a DIN-rail module, so allocate panel door or subplate space accordingly. Shock rated at 12 g for 11 ms, vibration at 7 mm / 2 g — robust enough for machine-mounted installation on packaging or material-handling equipment.","metaTitle":"Siemens 3RK1315-6NS71-0AA3 SIRIUS Direct Starter, 4kW/400V,","metaDescription":"Siemens 3RK1315-6NS71-0AA3 SIRIUS direct motor starter, 4 kW at 400 V, Trip Class 10, IP65, AS-Interface, 24 V DC.
