The 6SL3120-1TE24-5AB0 is a SINAMICS S120 Single Motor Module, listed as a spare part. It takes a 600 V DC bus and delivers 400 V three-phase AC at 45 A, with internal air cooling. The unit ships with the DRIVE-CLiQ cable modules and is painted — that last bit matters if you're matching a panel's existing look or dealing with environmental exposure.
What the ratings mean
The 45 A output at 400 V three-phase is the motor-side rating — it's sized for a standard 22 kW induction motor on a 400 V line, give or take depending on duty cycle. The 600 V DC input tells you it's designed for a common DC bus topology, typical in SINAMICS S120 multi-axis systems. Internal air cooling means it pulls ambient air through the heatsink; keep clearance around the module for airflow, and don't stack it tight against a heat source in the cabinet.
