It is designed for distributed motor control where the starter sits near the motor rather than in a central panel, saving cabinet space and reducing point-to-point wiring. Rated 5.5 kW at 400 V (7.5 hp at 460/480 V, 10 hp at 575/600 V), it covers the common small-motor range for pumps, fans, conveyors, and small compressors in industrial and infrastructure installations. ## Supply voltage, motor power, and trip coordination The control supply is 24 VDC nominal, with a permissible range of 20.4 to 28.8 V DC — the 26.5 V minimum permissible and 31.6 V maximum permissible define the absolute limits for the internal electronics. A 24 VDC supply with ±15 % regulation keeps the unit inside its operating window. Motor power ratings are given per voltage region: 5.5 kW at 400 V, 5 500 W at 500 V (same value, different notation), 3 hp at 220/230 V, 7.5 hp at 460/480 V, and 10 hp at 575/600 V. The Trip Class is CLASS 10, meaning the overload relay trips within 10 seconds at 7.2× the set current — standard for general-purpose motor protection where the starting time is short. ON-delay time is 85 ms, OFF-delay time is 65 ms — these are the internal response times from the AS-Interface command to the power contacts changing state. For sequencing multiple starters, account for these delays in the PLC logic if coordinated start/stop timing matters. ## Mounting, enclosure, and environmental fit The unit measures 159 mm deep, 294 mm wide, and 215 mm high, with screw fixing as the fastening method. Mounting can be vertical, horizontal, or flat — the recommended orientation is horizontal, which aligns with the natural convection path for the overload relay's thermal memory. IP65 protection means the enclosure is dust-tight and protected against low-pressure water jets — suitable for washdown areas, outdoor cabinets, and locations where the starter is mounted directly on the machine frame rather than in a sealed panel. Pollution degree 3 confirms it is rated for conductive pollution typical of industrial floors. Operating temperature range is -25 to +55 °C, with storage and transport limits of -40 to +70 °C. Shock resistance is 12g for 11 ms, and vibration resistance is 7 mm at 2g — adequate for mounting on machinery with moderate vibration, though a direct-coupled pump or fan on a rigid base is the typical fit. ## I/O, fieldbus, and connectivity The starter communicates via AS-Interface protocol — no PROFIBUS DP or PROFINET on this variant. AS-Interface is a bit-level fieldbus suited for simple on/off control and status feedback from distributed devices; it carries the start/stop command and returns the overload trip signal and motor current data. Four digital inputs are integrated into the unit, allowing local pushbuttons or sensors to be wired directly without a separate I/O block. Device addressing is via an M12 plug, and the main current circuit connects through a HAN Q4/2 connector per ISO 23570 — a standard industrial rectangular connector for motor power. On-site operation is supported — meaning the starter can be manually operated via a local button or selector switch for commissioning and maintenance, independent of the fieldbus command.","metaTitle":"Siemens 3RK1315-6LS41-2AA5 SIRIUS Motor Starter","metaDescription":"Siemens 3RK1315-6LS41-2AA5 SIRIUS direct starter, 5.5 kW at 400 V, IP65, AS-Interface, Class 10.
