Buyer questions
What exactly is being ordered?
The order must state LT3SA00ED in full, with quantity, equipment tag and required accessories. The category collage is a reference image and is not a photograph of the exact LT3SA00ED configuration.
What makes the selection valid?
For LT3SA00ED, 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 LT3SA00ED.
What must maintenance retain?
Keep the delivered LT3SA00ED label, configuration or setting backup, and acceptance-test record. These help identify the installed LT3SA00ED during later service.
Inspection before energising
Inspect LT3SA00ED on receipt for the exact suffix, readable nameplate, undamaged body and matching terminals. Compare the manufacturer data for LT3SA00ED 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 LT3SA00ED, isolate the equipment, retain wiring identifiers and save any programmable settings. Complete a controlled functional test after LT3SA00ED is fitted, with the responsible engineer approving any changed protection or control behavior.
Similar-looking designation register
These 5 codes share the visible LT3S pattern with LT3SA00ED 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 LT3SA00ED should contain the full model code, source document, selected site parameters, accessories and test result. This makes a future repeat order of LT3SA00ED traceable while keeping other similar-looking models distinct.
Additional Schneider LT3 visually similar model codes
These ordering strings are grouped because their printed model codes look similar. They may represent different product types, functions, ratings, accessories or approvals. This list is not an interchangeability claim; verify the exact manufacturer data before ordering.
