What it is and what it does
The Siemens 6SL3330-1TH41-4AA3 is a SINAMICS S120 Basic Line Module rated for 1400 A output at DC 675–930 V, fed from a 3-phase 500–690 V AC supply at 50/60 Hz. It delivers 1100 kW of rated power in a chassis (IP00) form factor with internal air cooling and includes a DRIVE-CLiQ cable for integration into the S120 drive system.
What the ratings mean for fit
The 1400 A DC output at 675–930 V DC is sized for the DC-link bus of a multi-axis S120 drive group — it supplies the common DC bus that feeds Motor Modules. The 1100 kW rated power tells you the motor load it can support in continuous duty. The 500–690 V AC input range covers 50/60 Hz grids worldwide; the IP00 chassis unit is intended for cabinet mounting where the enclosure provides the IP rating. Internal air cooling means it draws ambient cabinet air across its heatsink — ensure adequate cabinet ventilation for the full 1100 kW load.
