Part identity and fit
The Siemens 6SL3064-3BB00-0AA0 is a spare-part blanking cover for the BOP20 operator panel interface on SINAMICS, SINUMERIK, and SIMOTION control units — specifically the CU3XX-X, NCU 7X0, or D4XX-X series. If you're replacing a missing or damaged cover on one of those drives or CNC controllers, this is the factory part that snaps into the front bezel opening to maintain IP2X finger protection and keep dust out of the display connector.
What it covers — and what it doesn't
This is strictly the plastic bezel cover for the BOP20 keypad slot. It does not include the BOP20 operator panel itself, the display, or any electronics — just the blanking plate that seals the cutout when the operator panel is not fitted. If your control unit has the BOP20 installed, you don't need this part. If the cover is missing or cracked, this is the correct Siemens spare to restore the enclosure integrity.
