For controlled power distribution
Standardized LV switchboard
ML-MPS400 provides a standardized platform with defined main, feeder and control-busbar references. It supports repeatable project arrangements while allowing circuit-level devices and interfaces to be engineered for the application.
- 01Standardized modular arrangement
- 02Separate feeder and control-busbar reference
- 03Defined enclosure and ventilation protection

Get to know the product and its documentation
Explore how the equipment is used, review the published reference data, and ask our team about anything you would like to understand.
Ask about the configuration
Ask our team about the enclosure, devices, interfaces and ratings before deciding whether this product is relevant to your application.
Review the evidence
SLVA distribution and compensation assemblies have different report scopes. The linked distribution reports must not be used to claim compensation-assembly performance, or vice versa. The linked Fangyuan distribution report covers the 2500 A configuration; the catalogue's 2000 A option is not independently established by that 2500 A report. Catalogue values are not a substitute for the report's tested model, configuration and conditions.
Understand the next steps
If you choose to explore a project, we can explain the drawings, inspection records and final documentation associated with the proposed configuration.

Reissued type-test reports: 2022 tests, 2024 descriptive reissue
SLVA 2500 A standardized LV assembly - reissued type-test reports
Corresponding range: ML-MPS400 →What this report covers
- Physical page 3 explicitly identifies this as the first reissue of the 2022 type-test report, with standard/name/address changes. The 2024 signature does not mean a fresh 2024 full test.
- The -ZJ report has a State Grid standardized-design basis, not an additional independent GB/T or IEC certificate.
- Marketing-family linkage is not authorization to extrapolate to untested assemblies or currents.
- The standard-report cover lists the 2023 GB/T editions, but its summary-page default-standard footnote retains GB/T 7251.12-2013. Preserve the source discrepancy and ask the laboratory to clarify the retained footnote; do not rewrite the original.
- The website model is a commercial family name; the original laboratory model and tested arrangement remain controlling.
- This is a Chinese GB/T report, not an IEC certificate or a blanket qualification of every offered configuration.
- Pass, inherited pass, document-review pass and N (not applicable or not tested) are kept distinct.
- Report scope has been reviewed against selected identity, change and result pages. A physical-page count alone is not a page-by-page completeness or authenticity audit.

Product questions
Get familiar with this product
What is the published reference for ML-MPS400?
The page lists the catalogue reference configuration for ML-MPS400. Final ratings and interfaces remain subject to the approved project documents.
Are the published dimensions fixed for every project?
No. The dimensions are a documented reference envelope. Final width, depth, height and lineup arrangement depend on the selected devices, ratings, cable interfaces and approved general arrangement.
What evidence can be requested?
SLVA distribution and compensation assemblies have different report scopes. The linked distribution reports must not be used to claim compensation-assembly performance, or vice versa. The linked Fangyuan distribution report covers the 2500 A configuration; the catalogue's 2000 A option is not independently established by that 2500 A report. Catalogue values are not a substitute for the report's tested model, configuration and conditions.
