The starter offers selectable trip classes 5, 10, 15, and 20. Class 10 is the standard for general-purpose motor starting; Class 20 gives more time for high-inertia loads like fans or centrifuges, while Class 5 protects motors with very short acceleration times. The 24 V DC control supply (20.4 to 28.8 V range, max 31.6 V) is standard for modern PLC-driven panels. Four digital inputs are built in, so you can wire start/stop and direction commands directly without an extra I/O block. Mounting is by screw fixing, and the unit can be installed vertically, horizontally, or flat — useful when panel space is tight or the machine frame dictates the orientation. Dimensions are 294 mm wide by 215 mm high by 159 mm deep. The main power circuit connects via a HAN Q4/2 plug (ISO 23570), and device addressing uses an M12 plug. It communicates over AS-Interface (no PROFIBUS or PROFINET on this variant), so it fits into an AS-i sensor/actuator bus architecture.","metaTitle":"Siemens SIRIUS 3RK1325-6LS71-3AA0 reversing starter, 5.5 kW","metaDescription":"Siemens SIRIUS 3RK1325-6LS71-3AA0 reversing motor starter, 5.5 kW at 400 V, IP65, AS-Interface, 4 digital inputs, trip classes 5/10/15/20.
