It operates on a 24 V DC supply (20.4... 28.8 V range) and provides a CLASS 10 trip characteristic, meaning it disconnects within 10 seconds under a locked-rotor condition — suitable for standard induction motor starting profiles. Rated at 0.75 kW at 400 V (0.7 hp at 460/480 V, 1 hp at 575/600 V), this unit is sized for fractional-horsepower loads such as small conveyors, pumps, or fans in distributed I/O architectures. The IP65 enclosure allows deployment in washdown or dusty environments without a separate cabinet — mount it directly on the machine frame or panel surface via screw fixing in vertical, horizontal, or flat orientation. ## Fieldbus integration and I/O Communication is via AS-Interface — no PROFINET or PROFIBUS DP onboard. Device addressing uses an M12 plug, typical for AS-i drop cabling. The starter includes 4 digital inputs for local sensors or limit switches, reducing the need for a separate I/O block. The main circuit connects via a HAN Q4/2 plug per ISO 23570, a standardized industrial connector for motor power. Supply voltage is fixed at 24 V DC; the permissible range is 20.4... 28.8 V, with a maximum of 31.6 V and minimum of 26.5 V — watch the lower end for brownout ride-through. Shock resistance is 12g / 11 ms; vibration resistance is 7 mm / 2g — adequate for machine-mounted applications near rotating equipment. ON-delay is 85 ms, OFF-delay 65 ms — these are fixed, not adjustable.","metaTitle":"Siemens 3RK1315-6KS41-0AA3 SIRIUS Motor Starter, AS-Interfac","metaDescription":"Siemens 3RK1315-6KS41-0AA3 SIRIUS direct motor starter.
