It integrates the switching and protection functions into a single IP65-rated enclosure, so it mounts directly on the machine frame or conveyor line rather than inside a central control cabinet. This qualifies the starter for washdown environments in food-and-beverage, chemical processing, or outdoor material-handling lines where a standard IP20 panel-mount contactor would require a separate enclosure. Trip class selection covers CLASS 5, 10, 15, and 20. For a motor with a long acceleration time (high-inertia load like a centrifuge or large fan), select CLASS 20 to avoid nuisance tripping during start. For a pump or compressor with a short start transient, CLASS 10 or 5 provides tighter thermal protection. The setting is adjusted on the unit; no additional modules are needed. The DC supply range of 20.4 to 28.8 V matches standard 24 VDC control systems, including those with long cable runs where voltage drop is a concern. The 4 digital inputs and 2 digital outputs allow direct connection of start/stop pushbuttons, selector switches, and status indicators without an external I/O block. Screw fixing is specified, so the starter bolts directly to a mounting plate or machine frame. Dimensions are 294 mm wide, 215 mm high, and 148 mm deep. The main circuit connection uses a plug according to ISO 23570 (HAN Q4/2), a standard industrial connector for motor power.","metaTitle":"Siemens 3RK1395-6LS71-0AD0 SIRIUS Direct Starter, IP65, 12A","metaDescription":"Siemens SIRIUS 3RK1395-6LS71-0AD0 direct motor starter.
