It's designed for starting and protecting three-phase motors up to 5.5 kW at 400 V, with a selectable trip class of 5, 10, 15, or 20 to match the motor's thermal characteristics. You can mount it directly on the machine frame in vertical, horizontal, or flat orientation, with screw fixing. The 5.5 kW at 400 V rating (12 A) matches a standard 7.5 hp IEC motor. The selectable trip class lets you tune the overload curve. Four digital inputs and two digital outputs are built in, so you can wire start/stop, fault reset, and status feedback directly without an external I/O block. The control supply is 24 V DC (20.4 to 28.8 V range) — standard for modern panels. At 294 mm wide, 215 mm high, and 148 mm deep, it's a substantial standalone enclosure — not a DIN-rail module. Plan for screw-fixing to a backplate or machine frame. The main circuit connects via a HAN Q4/2 plug (ISO 23570), which means pre-wired harnesses or a quick-connect panel interface.","metaTitle":"Siemens 3RK1395-6LS71-2AD0 SIRIUS Motor Starter, IP65, 5.5 k","metaDescription":"Siemens SIRIUS 3RK1395-6LS71-2AD0 direct motor starter.
