It integrates a contactor and overload relay in a single IP65-rated enclosure, ready for direct-on-line reversing of three-phase motors up to 0.75 kW at 400 V (2 A). The 24 V DC control supply keeps it compatible with standard PLC outputs. Trip Class is selectable between 5, 10, 15, and 20, letting you match the overload protection to the motor's thermal time constant — a Class 10 setting is typical for standard induction motors, while Class 20 suits high-inertia loads like fans or centrifuges. This is a reversing starter — it includes two contactors mechanically interlocked to swap motor phase rotation, so one unit handles forward/reverse control without external interlocking relays. Four digital inputs and two digital outputs are onboard for local pushbuttons or a PLC, reducing wiring to a single 24 V DC supply and a motor cable. Mounting is by screw fixing; the enclosure accepts vertical, horizontal, or flat orientation. The main circuit connects via a HAN Q4/2 plug per ISO 23570, so pre-wired harnesses or panel-mounted receptacles mate directly. Dimensions are 294 mm wide, 215 mm high, 148 mm deep — plan for a 300 mm wide gland plate or backplate cutout. Vibration resistance is 7 mm / 2g, shock resistance 12g / 11 ms, suitable for machine-mounted duty.","metaTitle":"Siemens SIRIUS 3RK1395-6KS41-3AD3 reversing starter, 0.75 kW","metaDescription":"Siemens SIRIUS reversing starter, 24 V DC coil, 0.75 kW at 400 V, 2 A AC-3, IP65.
