The Siemens 3RK1395-6KS71-0AD5 is a SIRIUS brand direct motor starter in an IP65-rated enclosure, rated for 0.75 kW at 400 V AC and 2 A at 400 V AC. It runs on a 24 V DC control supply and offers selectable trip classes 5, 10, 15, and 20. With 4 digital inputs and 2 digital outputs, it's a self-contained motor starting and protection unit for standalone or distributed installations.
The 0.75 kW rating at 400 V AC sets the maximum motor size this starter can handle in a standard three-phase system. The trip class selection — 5, 10, 15, or 20 — lets you match the overload protection to the motor's starting profile: Class 10 for standard start, Class 20 for high-inertia loads like fans or conveyors that take longer to accelerate. The 24 V DC control supply is the standard for modern safety and PLC-controlled panels.
Mounting is by screw fixing, with approved positions vertical, horizontal, or flat. The recommended orientation is horizontal. Dimensions are 294 mm wide, 215 mm high, and 148 mm deep — plan your gland plate and side clearance accordingly. The main circuit connection uses a plug according to ISO 23570, HAN Q4/2 format, so pre-wired harnesses or panel-side receptacles need to match that interface. Environmental limits: operate from -25 to +55 °C, store or transport from -40 to +70 °C. Shock resistance is 12g for 11 ms; vibration resistance is 7 mm at 2g.
