What it is and where it fits
The 6SL3266-1EC00-0DA0 is a Siemens SINAMICS G120 shield plate for the FSC push-through frame size. It ships as a complete kit — shield plate plus mounting accessories — so you don't have to source hardware separately. This plate clamps the motor and line cable shields at the drive entry point, keeping radiated emissions inside the cabinet and preventing coupled noise from tripping downstream sensors. In a G120 FSC push-through build, omitting it means the drive passes EMC pre-compliance but may fail the full radiated-emission test on the line side.
Lifecycle and sourcing posture
For a BOM-line planner, mature is the safest slot: no looming last-time-buy, no PCN-driven respin. The part is sourced and quoted to order against an RFQ through independent distribution; availability and current pricing are confirmed at quote time.
Integration note for panel builders
The FSC push-through frame mounts the drive so its heat sink protrudes through the back panel, and this shield plate bolts onto the front side around the cable entry. Verify the panel cutout matches the FSC push-through template before fitting — the plate is sized for that specific frame, not the standard FSA/FSC book-size variant.
