Siemens SINAMICS G120X 11 kW Motor Drive Module
G120X drive comparison (seed vs. alternates)
Compare the seed and all in-catalog parametric alternates before design commit. Numbers are from records only; similarity is a catalog proximity signal, not a quality rank.

Why these are similar: All are Siemens SINAMICS G120X family units with identical voltage window, current rating, power class, chassis mounting, and IP20 form factor. The suffix difference identifies firmware variant and regional encoding; electrical and mechanical interfaces are shared across the block.
Drive family — suffix coding and selection
The G120X series encodes function and firmware in the trailing suffix. Units bearing U or UF suffixes (UF0, UB0, UP0) target standard drive configurations with universal firmware. The C-suffix variants (AF0, AB0, AP0) apply firmware tuned for specific control modes or regional certifications. The digit preceding the suffix (260 vs 261) indicates frame size or filtering variant within the same power band. All share a 19 A output stage at 500–690 V three-phase and the same chassis-mount form factor. Panel builders selecting a replacement or spares unit should match suffix code to the existing inverter configuration to avoid parameter mismatches at startup.
Thermal and environmental limits
All listed variants operate within a 20°C to 45°C ambient window. This constrains cabinet placement: ventilation paths must not introduce intake temperatures above 40°C under worst-case load. Chassis mounting requires direct attachment to a grounded metal substrate; the module relies on the enclosure backplane for thermal dissipation. Designers should verify that the enclosure thermal model maintains substrate temperature below the upper limit at full 19 A output with the specified 11 kW motor load.
Mechanical and compliance notes
IP20 rating means the unit is intended for enclosure-internal mounting with no direct operator access to live parts. The box package ships with the module as the sole item; no integral line filter or external brake chopper is included at this part number. ROHS3 compliance covers the component level; system-level compliance depends on the parent assembly. The chassis-mount tab pattern matches standard G120X frame sizes; verify mechanical fit against the existing inverter slot before procurement.
