Reviewing SEPAM M20 legacy Sepam Series 20 motor-protection relay for an installed system
SEPAM M20 is the exact designation used for this legacy Sepam Series 20 motor-protection relay entry. The picture is a shared Schneider-category reference collage, not an exact photograph of SEPAM M20. Use the confirmed details below as the starting point for enquiry; the installed label and current manufacturer document govern final selection.

Site information to collect
Before ordering SEPAM M20, write down the existing equipment tag, location and duty. Preserve the settings and test plan; a P-series modernization needs an engineering study. Capture a legible photograph of the complete SEPAM M20 marking so that voltage, option suffix and revision can be compared with the quotation.
Check the mating equipment around SEPAM M20: supply and load wiring, mechanical mounting, protection, communications or software interface as appropriate. The table intentionally separates documented facts from values that depend on a complete configured variant. Never infer a missing rating from a shared image or from another model whose code merely resembles SEPAM M20.
Quotation worksheet
- Complete SEPAM M20 designation and quantity
- Condition, revision and applicable manufacturer documentation
- Included accessories, exclusions and delivery region
- Any proposed substitution identified separately for approval
For SEPAM M20, ask the supplier to quote the exact reference and disclose any deviation. A suffix, pole count, communications port, certification or terminal style can change the installation even when the front appearance is similar. If the original SEPAM M20 is obsolete, confirm availability and obtain an engineering-reviewed migration path rather than assuming a current series is a direct swap.
Installation and commissioning record
Keep the isolation and safety procedure for the equipment that uses SEPAM M20. Compare delivered markings, package condition and accessories with the approved order. Record hardware and firmware revisions where present; preserve settings and backups before an installed SEPAM M20 is removed.
The acceptance test for SEPAM M20 should match its actual duty: switching or trip performance, protective settings, measured values, motion direction, software connection or busway continuity as applicable. Use qualified personnel and the manufacturer's commissioning instructions. A passing visual inspection alone does not prove that SEPAM M20 is correctly configured.
Similar-looking designations
No additional unassigned SEPAM M-pattern code is indexed with SEPAM M20. A different complete designation still requires its own technical check.
Release decision
Approve SEPAM M20 for procurement only after the exact model, documented product role, site connections and supplier offer agree. Keep SEPAM M20 on the purchase and receiving records. If a substitute is proposed, document the differences and obtain approval before fitting it.
