Terminal module providing U1/U2 potential-group infeed for compatible ET 200S PM-D power modules.
Siemens 3RK1903-0AA00 is a terminal module for the SIMATIC ET 200S PM-D motor-starter platform. Siemens identifies the exact order number for use with a PM-D power module and specifies potential-group infeed for U1 and U2. The product is shown with the lifecycle wording Prod. Cancellation. Siemens also points users toward the ET 200SP system with compact motor starter modules as the successor system, so retrofit planning must review both mechanical and electrical compatibility.
