What it is and what it does
The Siemens 6SL3210-1SE16-0UA0 is a SINAMICS S120 PM340 power module — the converter stage that takes a 380-480 V three-phase supply and delivers 5.9 A (2.2 kW) to the motor. It's a blocksize FSB unit with internal air cooling, built for the modular S120 drive architecture.
Where it fits
This PM340 mounts in a control cabinet as part of a SINAMICS S120 drive line-up. The blocksize FSB form factor and internal air cooling mean it's designed for panel integration with standard clearance around the heatsink — no external ducting required for this power class.
