The enclosure is IP65, so it's built for washdown environments or outdoor installation — no separate cabinet needed if the location is within the -25 to +55 °C operating range. Communication is over AS-Interface (the M12 addressing plug is standard), and the main power connects via a HAN Q4/2 plug per ISO 23570. The 0.75 kW at 400 V rating is the AC-3 motor-switching capability — that's the number that governs whether it handles your load. The IP65 rating means the entire starter, including the electronics and the HAN Q4/2 connector, survives hose-down cleaning, so it's suited for food-and-bev lines or outdoor conveyor sections without a separate panel. Trip class flexibility (5/10/15/20) is the practical differentiator here: you dial in the overload curve to match the motor's starting duration without nuisance tripping. A 0.75 kW pump on a direct start might use Class 10; a crusher with a long acceleration could need Class 20. The 24 V DC control supply is standard for modern PLC-driven panels. Mounting is by screw fixing, and the unit can be installed vertically, horizontally, or flat — so it adapts to whatever orientation the enclosure or machine frame allows. The dimensions are 294 mm wide by 215 mm high by 159 mm deep, which is a compact footprint for a reversing starter with integrated overload and AS-i interface. The HAN Q4/2 power connector and M12 AS-i addressing plug mean field wiring is plug-and-play, not a terminal-by-terminal exercise.","metaTitle":"Siemens 3RK1325-6KS71-1AA5 SIRIUS Reversing Starter, 0.75 kW","metaDescription":"Siemens SIRIUS 3RK1325-6KS71-1AA5 reversing motor starter. 0.75 kW at 400 V, IP65, AS-Interface, trip classes 5-20.
