SIRIUS direct starter with AS-Interface — 0.75 kW, IP65
The Siemens 3RK1315-6KS41-2AA5 is a SIRIUS direct motor starter rated for 0.75 kW at 400 V AC, with a Trip Class 10 overload protection curve. It is designed as a fully enclosed unit with IP65 protection, suitable for installation directly on machinery or in washdown areas without a separate control cabinet.
The 0.75 kW rating at 400 V defines the maximum standard induction motor this starter can handle in a direct-on-line application. The Trip Class 10 means the overload relay trips within 10 seconds at 7.2× the set current — standard for general-purpose motor protection on pumps, fans, and conveyors where starting time is under 10 seconds. This allows mounting on the machine frame or in food-grade zones where hose-down cleaning is routine, without needing a separate panel. Communication is via AS-Interface, a two-wire fieldbus that carries both power and data. The starter includes four digital inputs for local sensors or pushbuttons, addressable through an M12 plug for device addressing. No PROFIBUS or PROFINET on this variant. Supply voltage range is 20.4 to 28.8 V DC, with a nominal 24 V DC. The unit is screw-fixed and can be mounted vertically, horizontally, or flat, though horizontal is recommended. Dimensions: 294 mm wide × 215 mm high × 159 mm deep.
