The Siemens 6SL3320-1TG28-5AA0 is a SINAMICS S120 Single Motor Module marked as a spare part, taking a 675 V to 1035 V DC input and delivering 500-690 V three-phase AC output at 85 A. It's a built-in unit with internal air cooling and ships with the DRIVE-CLiQ cable. The 85 A rating tells you the continuous motor current it can handle — match it to the motor nameplate FLA, not the supply breaker. The DC input range means it's fed from a common DC bus or a line module, not directly off the mains.
Built-in construction with internal air cooling — plan for cabinet airflow around the module, not ducted or liquid cooling. The DRIVE-CLiQ cable is included, so the communication link to the Control Unit is ready to plug. On the DC bus side, the 675-1035 V range covers common 600 V and 690 V drive system DC links. The 85 A output at 500-690 V 3AC suits a motor in the 75-90 kW range depending on voltage and duty cycle.
