This unit is a SINAMICS G120X frame-size C filter-stage interface module rated for 45 kW AC motors on medium-voltage supplies. The 71 A output rating aligns with standard IEC motor sizes in that power band.
Design Trade-offs for Panel Integration
- Chassis mounting only — no DIN rail option; panel-cut or sub-plate fabrication required during enclosure build.
- 71 A output current demands correctly sized motor-branch conductors and thermal coordination with upstream protective devices; verify cable ampacity per local wiring rules.
- 20–45°C operating window restricts deployment to climate-controlled enclosures; supplemental enclosure cooling may be needed in warm switchgear rooms.
- 500–690 V AC input range suits medium-voltage pump, fan, and compressor drives but requires confirmation that the upstream supply characteristics match before system-level commissioning.
Comparison Against Siemens G120X Family Members
The reader must independently verify fit for a given application. All listed alternates share the same voltage window, current rating, and power class.

| Similarity | — | 1.0 | 1.0 | 1.0 |
Why similar: All parts carry the same SINAMICS G120X series designation, identical electrical ratings, and chassis-mount form factor. Differences reside in suffix codes (AB0/AF0/AP0/UB0) that typically denote variant-specific firmware, filter class, or factory configuration—details that require confirmation against Siemens ordering documentation before selection.
