SINAMICS S120 Basic Line Module — 355 kW, 430 A DC
The Siemens 6SL3330-1TH34-3AA3 is a SINAMICS S120 Basic Line Module that converts 3-phase AC supply (500-690 V, 50/60 Hz) into a regulated DC link of 675-930 V, rated at 430 A continuous output. This supports a motor power rating of 355 kW in a chassis IP00 format with internal air cooling. It ships with a DRIVE-CLiQ cable for integration into the S120 drive system. Rated for 430 A DC output at 675-930 VDC, this module feeds the common DC bus of an S120 multi-axis system. The 355 kW rating assumes typical motor loads; actual axis power draw depends on the sum of connected Motor Modules and their duty cycles.
Deployment Context
As a chassis IP00 unit with internal air cooling, this module mounts inside a switchgear cabinet, not as a standalone enclosure. The 500-690 VAC input range suits it for global 690 V industrial grids common in heavy process industries (steel, mining, marine) as well as 575-600 V North American installations. The regulated DC bus at 675-930 VDC powers downstream SINAMICS S120 Motor Modules for coordinated multi-axis drives.
