The Siemens 3RA9011-2AC03 is a motor starter configured as a WASH TEC box variant 8 PV 1/1, covering the 1.1 to 4 kW power band with an FA (factory-assigned) setting — meaning it ships pre-set for a specific motor current, not field-adjustable. It belongs to the Siemens Motor Starters category, used for direct-on-line or reversing control of three-phase motors in washdown environments — the WASH TEC designation points to a housing rated for high-pressure spray and chemical cleaning, typical in food-and-beverage or pharmaceutical lines.
What the WASH TEC box variant means for installation
The WASH TEC box variant 8 PV 1/1 is a sealed enclosure variant — the housing is designed to withstand washdown spray, so the starter mounts directly in the wet zone without a separate panel enclosure, saving DIN-rail space and gland-plate penetrations. The 1.1-4 kW power range covers most small pump, conveyor, and mixer motors in hygienic zones — the FA setting locks the overload relay to a factory-calibrated current, so the installer does not need to dial in the trip point on site.
