SINAMICS S120 Active Line Module — spare part designation
The Siemens 6SL3330-7TE35-0AA0 is a SINAMICS S120 Active Line Module, factory-tagged as a spare part. It converts a three-phase 380-480 V AC input at 50/60 Hz to a regulated 600 V DC bus, rated at 500 A continuous output for 300 kW of drive power. Internal air cooling handles the thermal load; the unit ships with the DRIVE-CLiQ communication cable for integration into the S120 drive system.
Lifecycle and sourcing posture
Siemens lists this Active Line Module at a mature lifecycle stage. That means the design is stable and the part remains in the active catalog — no discontinuation notice on record, but also no active development. For a BOM-critical line item like this 300 kW front-end, the mature status signals that a long-term supply agreement or a last-time-buy trigger should be on the procurement radar. The part carries a Siemens copyright date of 03.08.2021, indicating the documentation baseline.
What the ratings mean for fit
The 500 A DC output at 600 V DC defines the bus capacity for the connected motor modules. 300 kW is the nominal drive power this line module can support.
