The 0XA00-5 at 0.55 kW fills the gap between the 0.37 kW baseline and the 0.75 kW workhorse — same 380 × 156 × 129 mm FSA envelope, same 364.5 × 145 mm mounting, same natural convection cooling. At 37.6 W power loss, it is 13% more efficient in heat rejection than the 0.75 kW unit — a small per-drive difference that becomes material at scale: a 500-drive installation saves 2.75 kW of total thermal load on the building HVAC compared to sizing every zone at 0.75 kW.

Where does 0.55 kW make sense?

Transfer zones, curve sections, and diverter arms where 0.37 kW is undersized but 0.75 kW is more than the mechanical load requires. The 1.7 A continuous output (3.4 A overload) matches SIMOGEAR 2KJ8 geared motors in the 0.37–0.55 kW class. For an OEM building hundreds of zones per year, the BOM savings from right-sizing transfer zones to 0.55 kW instead of defaulting to 0.75 kW accumulate — without sacrificing the unified FSA mounting platform or the PROFINET integration common to every G115D on the line.
