Before the order
Use the complete XVUC21B code in the quotation and verify the installed nameplate, wiring schedule and enclosure or mounting constraints. Similar-looking parts may have different duties from XVUC21B.
Commissioning gate
Check the number of signal units and mounting method. Confirm this against the installed XVUC21B label and the current manufacturer documentation.
Receiving and installation record
When XVUC21B arrives, record the packing label and compare it with the permanent product marking. Inspect the terminals, housing and supplied accessories. Quarantine a mismatch instead of assuming that a related code can replace XVUC21B.
Installation of XVUC21B should follow an isolation plan and the current Schneider Electric instructions. Record torque or connector checks, settings, program backups and functional-test results where relevant. The commissioning file should tie every result back to XVUC21B and its equipment tag.
Visually related model codes
These 6 remaining designations share a visible XVUC pattern with XVUC21B; they are listed here rather than published as separate pages. This visual grouping does not establish identical ratings, functions, or interchangeability with XVUC21B.
Maintenance handover
Keep the exact XVUC21B designation with source documentation, equipment tag, acceptance test, and any settings or program archive. At the next maintenance visit, compare the installed XVUC21B code with the recorded XVUC21B order before replacing or reconfiguring the device.
