425 A DC bus supply for multi-axis S120 drives
The 6SL3330-7TE33-8AA3 is a SINAMICS S120 Active Line Module that takes three-phase 380-480 V AC input and delivers a regulated 600 V DC bus at 425 A, supporting a continuous power rating of 235 kW. It includes a Drive-CLiQ cable for direct communication with the S120 control unit and other modules on the shared DC link. Internal air cooling means it draws cabinet air across the heatsink — plan for adequate panel ventilation or a top-mounted exhaust fan to keep ambient within the module's operating range.
Physical fit in the cabinet
Packaged dimensions are 326 x 1533 x 545 mm — this is a tall, narrow module that mounts vertically in the S120 cabinet frame. The 235 kW rating at 425 A DC output means it feeds a multi-axis drive group; confirm the total motor load plus regenerative braking power stays under the module's continuous current limit.
