Spare-part BOP for the SINAMICS G110 / G120 drive
The Siemens 6SL3255-0AA00-4BA1 is the Basic Operator Panel that snaps onto the SINAMICS G110 / G120 family of drives, giving local start/stop, frequency setpoint and parameter read/write without a laptop or fieldbus terminal. It is catalogued as a spare part, so the typical use is to replace a lost or failed BOP on an existing drive rather than to be ordered alongside a new drive shipment.
Cabinet footprint and sealing envelope
Protection degree is IP20, which is appropriate for mounting behind a cabinet door on a control desk — not for an open washdown or outdoor enclosure. Storage temperature is rated -40 … 70 °C, so spares held in a parts cupboard for a fault call-out stay within spec on the shelf.
Mature lifecycle — what that means for spares
Condition is new, which matters on a panel door that an operator handles daily — a second-hand BOP with a worn keypad or a faded display is the usual failure mode that drives this kind of replacement order. Shelf No. 230520 is the internal stock-keeping reference for this lot; nothing in the listing names an official successor panel, so the drop-in spare for an existing G110 / G120 stays this same code.
