The Siemens 6SL3210-1SE17-7AA0 is a SINAMICS S120 Power Module PM340, officially designated a spare part. It takes a 380-480 V three-phase AC input at 50/60 Hz and delivers a 3-phase AC output rated 7.7 A, corresponding to 3.0 kW of motor power. The unit is built in blocksize FSB with an integrated line filter and uses internal air cooling, so it pulls ambient air through the heatsink — no external coolant loop needed.
Fit and integration notes
The built-in line filter saves panel space and avoids an external EMC filter add-on. Internal air cooling means you need clearance above and below the module for airflow — check the Siemens mounting clearances for FSB to avoid derating. The 7.7 A output (3.0 kW) is sized for a standard 4-pole induction motor on 400 VAC three-phase; match the motor's full-load amps to this rating for continuous duty.
