Inspection dossier for Schneider MD20SR-24M spring-return modulating damper actuator
The full MD20SR-24M designation is the anchor for this spring-return modulating damper actuator enquiry. The shared main image illustrates a Schneider-related category rather than the exact MD20SR-24M unit. Use the physical nameplate and site drawing to settle the identity before comparing offers.

Only the documented facts above are stated for MD20SR-24M. A family description, shortened code or supplier photograph cannot establish every rating and option. Record missing MD20SR-24M data as an open item rather than assuming a standard variant.
1. Identify the installed item
Photograph the front label, side markings, terminals and accessories of MD20SR-24M. Capture the assembly location, serial or revision where present, and the surrounding equipment. If the site refers to MD20SR-24M by a short name, check that it matches the complete supplier reference.
Trace MD20SR-24M in the electrical or control drawing and write down its actual job. For a switch or breaker, inspect the circuit and protection arrangement; for a drive or control board, check rack, firmware and cables; for a sensor or actuator, check signal, mechanical fit and process conditions.
2. Compare the proposed supply
Full code, revision, origin and condition.
Terminals, connectors, dimensions and mounting.
Inspection, documented test and warranty scope.
Request a quotation explicitly naming MD20SR-24M, not simply a visually similar item. Compare the offer to the installed MD20SR-24M with regard to ratings, environmental limits, connector coding and any required certificate. A substitute needs a separate written engineering approval.
The availability and lifecycle status of MD20SR-24M may differ by region and date. Ask whether the offered MD20SR-24M is factory-new, surplus, repaired or refurbished, and whether traceability and return rights apply. These commercial details are part of a usable maintenance decision.
3. Receive and test
At goods receipt, match the delivered MD20SR-24M label to the approved order, inspect packaging and verify all included connectors or accessories. A qualified technician should follow the site's isolation procedure before installing MD20SR-24M; the functional test must reflect the actual application.
Record test results, deviations and any replacement cross-reference next to MD20SR-24M in the asset history. If a claim about MD20SR-24M cannot be linked to a manufacturer document or the installed unit, keep it unresolved until the responsible engineer signs it off.
Other visually similar designations
A related code is a search reference only. It is not proof of identical manufacturer, function or interchangeability.
No further unassigned MD20SR-pattern code is grouped with MD20SR-24M in this dossier. That does not establish uniqueness or an approved replacement for MD20SR-24M.
Enquiry release
Release the MD20SR-24M purchase enquiry when the exact code, technical boundary, offer condition and acceptance plan agree. Retain the full MD20SR-24M wording in the order and receiving record so that any later variation is visible.
