It accepts a 24 V DC control supply (20.4... 28.8 V range) and offers selectable trip classes 5, 10, 15, and 20, letting you match the overload curve to the motor's starting profile — a pump or fan with a long acceleration ramp needs class 20; a short-acceleration conveyor can run class 5 or 10. The enclosure carries an IP65 rating, so the unit is suited for washdown environments or outdoor cabinets where dust and hose-directed water are present. It mounts via screw fixing and accepts multiple orientations — vertical, horizontal, or flat — though horizontal is the recommended position for heat dissipation. The unit measures 294 mm wide by 215 mm high by 148 mm deep. That 148 mm depth is the dimension that matters most for enclosure depth clearance — standard 200 mm deep enclosures leave roughly 50 mm behind the unit for cabling and the HAN Q4/2 connector. The 294 mm width means it occupies about three 100 mm DIN-rail mounting slots; plan your backplate layout accordingly. It withstands 12 g shock for 11 ms and 2 g vibration at 7 mm amplitude — figures that cover most industrial conveyor and machine-tool applications without additional dampening.","metaTitle":"Siemens 3RK1395-6KS71-2AD3 SIRIUS Motor Starter, 0.75 kW, IP","metaDescription":"Siemens 3RK1395-6KS71-2AD3 SIRIUS direct motor starter, 0.75 kW at 400 V, IP65, 4 DI / 2 DO, trip class 5/10/15/20.
