The Siemens 6SL3260-6AB00-0DA0 is a SINAMICS G120 Installation frame FSB push-through — the mechanical chassis that the drive module mounts into for panel integration. This is the push-through variant, meaning the heat sink protrudes through the panel cutout, keeping the electronics on the cool side of the enclosure.
Integration Note
The FSB push-through frame is sized for the lower power range of the G120 family. When specifying the panel cutout, account for the push-through lip and the clearance needed for the heat sink fins on the rear.
