The Siemens 6SL3255-0VA00-4BA0 is a SINAMICS V20 Basic Operator Panel (BOP) spare part, sized 91x97x32 mm (WxHxD). This is the front-panel interface for local drive control, parameter access, and status readout on V20 frequency inverters.
The document base carries a revision date of 17.02.2021 with copyright to Siemens 2021, indicating the technical specification and spare-part classification were current as of that date.
The 91x97x32 mm footprint mounts directly into the V20 drive's front-panel cutout, replacing a lost or damaged BOP without additional wiring or configuration. No DIN-rail or panel-mount hardware required — it clips onto the drive chassis.
