PM340 power module — what it is and what it fits
The Siemens 6SL3210-1SE21-0AA0 is a SINAMICS S120 Power Module PM340 in blocksize FSB, rated for 380-480 V 3AC input at 50/60 Hz and delivering 10 A (4.0 kW) three-phase output. It includes a built-in line filter and uses internal air cooling. The blocksize FSB form factor means it mounts directly on a DIN rail or panel plate in a standard control cabinet — no special bracket needed.
What the ratings mean for fit
The 10 A output at 4.0 kW is the continuous motor rating under typical induction-motor load — sized for a 4-pole motor in that power band. The built-in line filter covers conducted emissions for the 380-480 V range, which saves panel space versus an external filter. The FSB blocksize footprint is compact: it shares the same mounting pattern as other PM340 FSB units, so swapping up or down in power within the frame size keeps the drill plan unchanged.
