Buyer questions
What exactly is being ordered?
The order must state SR3B261BD in full, with quantity, equipment tag and required accessories. The category collage is a reference image and is not a photograph of the exact SR3B261BD configuration.
What makes the selection valid?
For SR3B261BD, compare the verified data above with circuit duty, supply, mounting, wiring and the current Schneider Electric instructions. Similar-looking codes do not prove interchangeability with SR3B261BD.
What must maintenance retain?
Keep the delivered SR3B261BD label, configuration or setting backup, and acceptance-test record. These help identify the installed SR3B261BD during later service.
Decision boundary
A buyer considering SR3B261BD should resolve this point: Preserve the program and map expansion modules before replacement. Document any deviation from the installed SR3B261BD configuration.
Inspection before energising
Inspect SR3B261BD on receipt for the exact suffix, readable nameplate, undamaged body and matching terminals. Compare the manufacturer data for SR3B261BD with the drawing and the physical installation. Do not rely on visual appearance or the shared image to approve a rating.
When replacing an installed item with SR3B261BD, isolate the equipment, retain wiring identifiers and save any programmable settings. Complete a controlled functional test after SR3B261BD is fitted, with the responsible engineer approving any changed protection or control behavior.
Similar-looking designation register
These 5 codes share the visible SR3B pattern with SR3B261BD and are consolidated here rather than becoming separate pages. Their individual voltage, contacts, range, connection, approval or size may differ; verify each complete code before use.
Procurement handover
The final purchase and commissioning record for SR3B261BD should contain the full model code, source document, selected site parameters, accessories and test result. This makes a future repeat order of SR3B261BD traceable while keeping other similar-looking models distinct.
