It is part of the SIRIUS product brand and is classified as a motor starter with a direct-start design. The unit is rated for 5.5 kW at 400 V, 7.5 hp at 460/480 V, and 10 hp at 575/600 V, making it suitable for a range of three-phase motor loads in conveyor, pump, and fan applications. The IP65 protection class means the enclosure is dust-tight and protected against water jets, allowing deployment in washdown or outdoor environments without an additional cabinet. The starter offers selectable trip classes 5, 10, 15, and 20, which define the maximum time the overload relay allows the motor to run under locked-rotor conditions. Class 10 is the standard for general-purpose motors; class 20 accommodates high-inertia loads like centrifuges or crushers. This flexibility lets the same unit cover multiple motor types without changing hardware. Power is supplied at 24 V DC (20.4 to 28.8 V range), and the unit includes four digital inputs for local control signals. Communication is via AS-Interface protocol, with device addressing through an M12 plug. The main current circuit connects via a HAN Q4/2 plug per ISO 23570, which is a standard industrial connector for motor power. ## Mounting and Environmental Ratings The starter is fastened with screw fixing and can be mounted vertically, horizontally, or flat, giving flexibility in panel layout. Dimensions are 294 mm wide, 215 mm high, and 159 mm deep. The recommended mounting orientation is horizontal for optimal thermal performance. Vibration resistance is rated at 7 mm / 2g, and shock resistance at 12g for 11 ms, suitable for machine-mounted applications.","metaTitle":"Siemens 3RK1325-6LS41-2AA5 SIRIUS Motor Starter, 5.5 kW at 4","metaDescription":"Siemens SIRIUS 3RK1325-6LS41-2AA5 direct motor starter, IP65, 24 V DC, 4 DI, AS-Interface, trip classes 5–20.
