The Siemens 6SL3263-1HA20-0GA0 is a SINAMICS G110D protection bar, designed for FSA and FSB frame sizes. It mounts across the drive terminals to prevent accidental contact with live conductors during maintenance or operation — a mechanical guard, not an electrical component.
Deployment context
This protection bar is a panel-mount accessory for SINAMICS G110D drives in FSA or FSB enclosures. It adds a physical barrier over the power terminals, which is relevant for installations requiring IP2X finger-safe access or compliance with local wiring rules for exposed conductors.
