It's sized for 5.5 kW at 400 V (7.5 hp at 460/480 V) and accepts 24 VDC control supply (20.4 to 28.8 V). Trip class is selectable among CLASS 5, 10, 15, and 20 — that's the maximum time in seconds the overload relay allows before tripping under a locked-rotor condition. Class 10 is the default for standard motor starting; Class 20 gives extra headroom for high-inertia loads like fans or centrifuges. The starter handles direct-on-line starts only (no reversing), so it's a fit for pumps, conveyors, and compressors that run one direction. Four digital inputs (M12, 24 VDC) are onboard for local start/stop and feedback — no separate I/O module needed. The main power circuit connects via a HAN Q4/2 plug (ISO 23570), which is a common industrial connector for motor feeds up to this power class. Mounting is flexible: vertical, horizontal, or flat, with screw fixing. The 294 mm width and 215 mm height are the panel footprint; depth is 159 mm including the connector.","metaTitle":"Siemens 3RK1325-6LS71-2AA0 SIRIUS Motor Starter, 5.5 kW 400V","metaDescription":"Siemens 3RK1325-6LS71-2AA0 SIRIUS direct motor starter, 5.5 kW at 400 V, IP65, AS-Interface, 4 digital inputs, trip classes 5-20.
