Siemens 6SL3120-1TE28-5AA3 SINAMICS S120 85 A Single Motor Module
Active 85 A internal-air-cooled module with 141 A maximum current in a 200 mm housing.
01Product Profile
Siemens 6SL3120-1TE28-5AA3 is the active 85 A Single Motor Module in the SINAMICS S120 booksize range. It delivers 68 A base-load current, 110 A S6 current and 141 A maximum current. The 200 mm module uses an M8 motor terminal, a 1,880 µF DC-link capacitance and 0.044 m³/s internal cooling airflow. Its engineering data is specific to the 85 A article and must not be scaled from the 60 A or 132 A modules.
