The highest-power G115D that still runs fanless. At 3 kW and 125.8 W power loss, the FSB heat sink handles all dissipation through natural convection — no moving parts in the cooling path. This is the drive to spec when the installation environment has airborne dust, fibers, or light debris that would clog a fan intake.

7.7 A rated output at 400 V. AB0 suffix: standard I/O with integrated brake control. The 7.12 kg FSB housing mounts directly on the machine frame near the motor — no control cabinet space consumed.

Step up to 4 kW in the same FSB frame and the integrated fan becomes mandatory (172.9 W exceeds the convection ceiling). For applications that value silence and zero fan maintenance over absolute power density, this 3 kW model is the sweet spot.
