The Siemens 6SL3330-1TH41-1AA3 is a SINAMICS S120 Basic Line Module rated for 3AC 500-690V, 50/60Hz input, delivering 1100A DC output at 675-930V, with a rated power of 900 kW. This is a chassis unit, IP00, with internal air cooling, and includes a DRIVE-CLiQ cable. It sits in a common DC-bus configuration for multi-axis drives — the Basic Line Module provides a regulated DC link without regenerative feedback, so braking energy is dissipated in a resistor rather than returned to the line.
Chassis unit IP00 means it is intended for enclosure mounting — no finger-safe cover, so it goes inside a cabinet with proper interlocking. Internal air cooling requires clearance around the heatsink; typical SINAMICS S120 practice is to mount with the heatsink ducted through the enclosure rear panel. The DRIVE-CLiQ cable is included, which simplifies connection to the Motor Module and Control Unit — one less item to order separately.
The 1100A DC output at 675-930V feeds a common DC bus that can supply multiple SINAMICS S120 Motor Modules. For a 900 kW rating, this module is sized for large drives — think conveyors, crushers, extruders, or test stands. The 500-690V input range covers 50/60 Hz grids globally, including 690V industrial networks common in European and Asian heavy industry.
