The middle rating is where flexibility pays twice — once for the loads that outgrow 0.75 kW, once for the line layouts that keep changing. The 2XL01-1AB0 build of the SINAMICS G115D covers both: 1.1 kW at 3.1 A rated in LO duty (6.2 A HO) on local I/O, with the Quickon power terminals wiring the 400 V AC feed in seconds rather than a gland in an hour.

What does the middle rating actually buy?

Resolution where small sections drift. A gate or transfer that stalls a 0.75 kW build on a loaded start draws 3.1 A of LO current here without leaving the frame — the 380 x 216 x 129 mm FSA housing, the fanless cooling and the maintenance picture are identical to the smaller builds. The 6.2 A HO capacity and 200%/3 s starting envelope absorb everything the 1.1 kW class produces.

Why choose Quickon terminals for a standalone section?

Because standalone sections are the ones that get moved between benches and cells during commissioning and troubleshooting. Quickon terminals are push-in fast wiring — the power connection survives repeated re-termination the way a gland does not. The integrated 24 V PSU, the C2 filter and the IP65/66 / UL Type 4X sealing are family constants; the local/remote switch hands control to whoever is standing in front of the section.
