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
Model-linked reports and independently prepared English reading guides are available below. Check the original model, current range, construction, standards and individual test scope. A change or reissue document is not a new full retest; catalogue values are not blanket certification for the range.

Standard-change / descriptive verification report
GCS low-voltage assembly - report chain
Corresponding range: ML-HCW400 →What this report covers
- Physical source page 3 states that this descriptive verification report must be used together with C-14201-DC193996.
- The original temperature-rise test used three 60/65 W axial fans (W2E20060HA3) operating below the incoming air circuit-breaker; see physical source page 3. Do not describe the 6300 A reference as naturally ventilated.
- LV-021 is another scan of the same report, not another independent test.
- 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.
