The power connection uses a HAN Q4/2 plug per ISO 23570, so field wiring is a plug-and-play affair — no opening the sealed housing. The 12 A at 400 V AC rating is the motor full-load current the starter can handle continuously. That translates to 5.5 kW on a 400 V three-phase motor, or 7.5 hp at 460/480 V. The trip class is selectable — Class 5, 10, 15, or 20 — so you match the overload curve to the motor's starting profile: a high-inertia fan or pump needs Class 20 to avoid nuisance tripping during start; a fast-cycling conveyor can use Class 5 for tighter protection. Shock resistance is 12g for 11 ms, vibration resistance 7 mm / 2g — figures that matter when the starter mounts on a machine that sees repetitive impacts or continuous vibration. The unit can be mounted vertical, horizontal, or flat, with screw fixing, giving flexibility in tight machine cavities.","metaTitle":"Siemens 3RK1395-6LS71-0AD5 SIRIUS Motor Starter, 12 A, IP65","metaDescription":"Siemens SIRIUS direct motor starter 3RK1395-6LS71-0AD5. 12 A at 400 V AC, 5.5 kW.
