Siemens ET 200SP Shielded BaseUnits

Siemens ET 200SP Shielded BaseUnits is usually shortlisted when the project already points to ET 200SP but shield handling, wiring segregation, or EMC-sensitive layout decisions are still open. It becomes relevant when the mechanical base-unit choice is tied to how cable shields, terminal layout, and potential groups need to be organized in the cabinet. Keep it separate from standard ET 200SP base units until the shielding requirement is clearly confirmed, especially on retrofit jobs.
