The Siemens 3RK1395-6LS41-0AD0 is a SIRIUS direct motor starter rated for 12 A at 400 V AC, delivering 5.5 kW at 400 V. It carries an IP65 enclosure rating, meaning the housing and connectors withstand washdown environments — suitable for food-and-bev lines or outdoor conveyor sections where hose-down cleaning is routine. Power supply is 20.4 to 28.8 V DC, with four digital inputs and two digital outputs onboard for local control and status feedback. The main circuit connects via a HAN Q4/2 plug per ISO 23570, so panel wiring is a pre-terminated cable assembly rather than individual lug terminations. Trip Class is selectable among CLASS 5, 10, 15, and 20, letting you match the thermal curve to the motor's start profile — a pump with a long acceleration ramp can use CLASS 20 to avoid nuisance trips, while a short-acceleration conveyor motor can run CLASS 10.
Mounting and Environment
Dimensions are 294 mm wide by 215 mm high by 148 mm deep. Mounting is screw fixing, and the unit can be installed vertically, horizontally, or flat — the horizontal orientation is recommended for optimal thermal performance. Vibration resistance is 7 mm / 2g; shock resistance is 12g for 11 ms, so it holds up on a machine frame or conveyor line. Operating temperature range is -25 to +55 °C; storage and transport range is -40 to +70 °C. Pollution degree 3 means it tolerates conductive dust and occasional condensation — typical for an unsealed control cabinet in a factory environment.
