It integrates the contactor, overload relay, and control electronics in one IP65 enclosure — suitable for washdown or dusty environments without a separate panel. The unit is powered by a 24 VDC supply (20.4...28.8 V) and communicates via AS-Interface, with 4 digital inputs and 1 digital output onboard. The trip class is selectable among CLASS 5, 10, 15, and 20 — meaning you can match the thermal overload curve to the motor's starting profile: CLASS 10 for standard induction motors, CLASS 20 for high-inertia loads like fans or centrifuges. The 24 VDC control supply is common across most PLC cabinets, but verify your AS-Interface master supports the protocol — this unit uses AS-Interface, not PROFIBUS or PROFINET. Mounting is screw-fixed, not DIN-rail, so plan for a dedicated backplate or enclosure floor. The unit can be installed vertically, horizontally, or flat, but the recommended orientation is horizontal for optimal heat dissipation. Shock resistance is 12g / 11 ms, vibration resistance 7 mm / 2g — adequate for most industrial machinery but not for extreme mobile equipment. The main power circuit connects via a HAN Q4/2 plug (ISO 23570) — a standard industrial connector that simplifies panel wiring and allows pre-fabricated cable assemblies. Device addressing is done through an M12 plug, typical for AS-Interface nodes. The 4 digital inputs can accept signals from pushbuttons, limit switches, or sensors; the single digital output can drive a status lamp or PLC input. Dimensions: 294 mm wide, 215 mm high, 159 mm deep. Allow clearance for the HAN connector and cable bend radius.","metaTitle":"Siemens 3RK1325-6KS71-3AA5 SIRIUS Reversing Starter, IP65, 4","metaDescription":"Siemens SIRIUS 3RK1325-6KS71-3AA5 reversing motor starter.
