The Siemens 6SL3120-1TE15-0AA0 is a SINAMICS Single Motor Module — explicitly labeled as a spare part, not a new-install variant. It takes 600 V DC on the DC link and delivers 400 V three-phase AC at 5 A, with internal air cooling and the DRIVE-CLiQ cable already included. That DRIVE-CLiQ pre-wire saves a step in a swap: you pull the old module, plug this one in, and the drive system re-identifies it on the next power-up.
The module is fed from the common DC bus. The 5 A output sizes it for a small servo or induction motor. Internal air cooling means it pulls ambient air through the heatsink.
