The Siemens 3RA9011-2AD04 is a Set for FA (fully assembled) WASH TEC box variant 9 PV, covering a motor power range of 5.5 to 11 kW. It is a pre-configured motor starter assembly designed for washdown environments in food-and-beverage or similar wet-process lines, integrating a contactor, overload relay, and enclosure into one unit.
Compatibility with 3RT2 contactors
The 3RA9011-2AD04 is a fully assembled WASH TEC box that includes the contactor and overload relay internally. It is designed to interface with the same 3RT2 contactor series for replacement or expansion, but as a complete unit it does not require a separate contactor purchase. For field replacement of the contactor element inside the box, the 3RT2 series is the correct match.
