28900 — Schneider Compact INS40 three-pole switch-disconnector: procurement passport
28900 identifies a Compact INS40 three-pole switch-disconnector. This page is a reference for identifying and quoting 28900; the common main image is a Schneider category collage, not a guaranteed picture of the exact unit. Read the complete designation on the installed component before selecting a replacement.

Configuration boundary
The record above gives only the facts that can be supported for 28900. It does not decode every suffix or establish every rating of 28900. Ask for the original datasheet or configuration printout when the installed assembly includes options, firmware, a trip unit, a cable, a sensor or an interface card.
For 28900, compare the equipment tag and system drawings with the visible markings. Confirm supply, poles, contacts, protocol, measured range, nominal force or network role as applicable. Do not copy a value from a similar-looking code. If a number is missing, leave it open until the manufacturer record or actual nameplate resolves it.
Procurement and receiving notes
Request an offer for the exact 28900 designation and required quantity. The offer should identify stock condition, manufacturer, document revision, included accessories and any exclusions. If the supplier proposes an alternative to 28900, ask for a separate written comparison rather than silently accepting a different product family.
At receipt, inspect the 28900 label, packaging and supplied accessories. Keep the serial or batch number when present. For a protection, safety or control component, preserve the old settings and approved wiring design before the existing 28900 is removed.
Site acceptance
Install 28900 only under the applicable isolation and safety procedure. Commissioning must test the specific installed function: switching or protection behavior, relay I/O, sensor response, communication, valve travel or cabling continuity as relevant. A visual match does not prove that 28900 has the correct settings or compatibility.
Record the test result and exact 28900 code in the maintenance file. If the part is obsolete or service status differs by region, verify stock and approved migration path with the manufacturer. Keep a separate note for substitutions because the replacement may require engineering changes.
Related-looking references
These 11 designations resemble the 28 portion of 28900. They are gathered here for finding an enquiry only; a related-looking reference can have a different function, rating or interface and is not automatically interchangeable with 28900.
Release statement
Use 28900 as the search and purchase reference only when the verified identity and the site's requirements align. Review each unconfirmed configuration item before issuing an order. This 28900 record is an identification aid, not a substitute for the manufacturer manual or a site-specific engineering approval.
