Product Details

• Part Number 1 3RK1304-5KS70-2AA3

Product Description

3RK1304-5KS70-2AA3 is identified by Siemens as a Direct Soft Starter 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. Selection should account for the intended surrounding hardware configuration.

Within an S7 installation, the exact hardware order number determines supported interfaces and configuration behavior. System and software compatibility should be checked before replacement. The original equipment schedule should guide compatibility review.

In the signal path, this approach helps preserve the intended system function while keeping selection aligned with the documented ratings, capacity, and compatibility requirements. This helps preserve the function assigned to the installed control node.
