Part identity and fit
The Siemens 6SL3065-2AA00-0AA0 is a replacement terminal block for SINAMICS, SINUMERIK, and SIMOTION drive and control modules — specifically the CU3xx, NCU 7x0.1/.2, D4xx, TB, TM, and SM families. It is a 4-pole, 24 V DC connector supplied without bolting, meaning it mates to the existing screwless header on the module face. The part carries group code R2SC and product group 9485, which are Siemens internal classification codes used for ordering and logistics.
