What this package does on the line
The 6SL3000-0GE21-0AA0 is a SINAMICS / SIMODRIVE subassembly that bundles a line filter and an HF line reactor into one orderable package for a 10 kW Smart Line Module. It takes a 3-phase 380-480 V, 50/60 Hz input and contains the line filter type 6SL3000-0HE21-0AA0 plus the HF line reactor type 6SL3000-0CE21-0AA0. If you are rebuilding a SINAMICS drive cabinet and need the EMC filter and reactor matched to a 10 kW Smart Line Module, this is the single order code that gets you both in one box — no separate sourcing, no mismatch risk.
What is in the box and where it fits
This is a panel-mount subassembly, not a standalone DIN-rail component. The line filter and HF reactor inside are sized for the 10 kW Smart Line Module's input harmonics and EMC compliance. Mount it close to the line entry in the drive cabinet — long pigtails between the filter/reactor and the module defeat the common-mode attenuation the reactor provides.
