The Siemens 6SL3100-0EE21-6AB0 is a SINAMICS line reactor sized for a 16 kW combi FTB line module. It sits on the input side, handling 380-480 V 3AC at 50/60 Hz — the standard three-phase supply for most European and North American industrial panels. The reactor's job is to smooth current draw and limit harmonic distortion from the drive's rectifier stage, which keeps the upstream transformer and bus from overheating on a multi-drive line.
RoHS compliant since 01-07-06, with REACH candidate list information available on request. No export control restrictions apply — AL: N, ECCN: N — so it ships without special licensing paperwork for most destinations.
Integration Note
Mount this reactor close to the line module input — long cable runs between the reactor and the drive's rectifier defeat the inductance and can radiate switching noise into nearby signal cables. The 16 kW rating matches the combi FTB module's continuous output; verify the line module's input current rating against the reactor's impedance curve if you are pushing the drive into overload duty cycles.
