Product Description

3RK1303-6DS74-3AA3 is identified by Siemens as a Motor Starter ECOFAST within the Simatic S7 family.

Within the control architecture, this product serves the equipment role stated in its description and should be selected by exact model identity rather than by appearance or a broadly similar name. Its role should remain distinct from that of similarly named assemblies.

Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. Its role should remain distinct from that of similarly named assemblies.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. Installation should follow the control node's approved hardware records.
