What it sits next to in the cabinet
The 6SL5100-0HE25-5DD0: It belongs to the Line filters for Smart Line Modules family and carries group code R220 under product group X0HX. A line filter goes upstream of the Smart Line Module to keep converter-side switching noise off the plant bus and to bring the drive stack within EMC limits — the S220 line filter is the dedicated Siemens match for that 55 kW SLM slot, not a generic mains filter.
Production status and class
Packaging quantity is one piece per unit, which matches how a single line filter is normally ordered to support one SLM stack rather than bought in bulk.
Compliance and substance declarations
RoHS compliance has been confirmed since 08-10-23. REACH Art. 33 disclosure is on file for lead, CAS-No. 7439-92-1, above the 0,1 % (w / w) threshold — a routine declaration for this filter class, not a restriction on its use in industrial cabinets. Export classification is AL:N / ECCN:EAR99H, which keeps cross-border shipment paperwork at the low end of the export-control scale.
