The Siemens 6SL3210-1SE21-0UA0 is a SINAMICS S120 Power Module PM340, designated as a spare part. It takes a 380-480 V 3AC, 50/60 Hz input and delivers a 3AC output rated at 10 A, corresponding to 4.0 kW of motor power. The module comes in the Blocksize FSB frame with internal air cooling.
What the Ratings Mean for Fit
The 10 A output at 4.0 kW is sized for a standard 4-pole induction motor on a 400 VAC three-phase supply — think a small conveyor, pump, or fan. The FSB Blocksize frame is the compact footprint; it mounts on a panel backplate, not a DIN rail, so plan for gland-plate clearance and cooling airflow around the heatsink. Internal air cooling means the drive relies on its own fan, not cabinet forced air, but derate the output if the ambient inside the enclosure climbs above 40 °C.
