What this report covers
  • This is an independently prepared English reading guide, not an English report issued by the test laboratory. The complete Chinese original follows unchanged and governs interpretation.
  • Results apply to the submitted sample, stated configuration, test conditions and listed tests only. They are not a blanket certificate for all Minglang products or all project requirements.
  • Marketing product names identify a website range; the source report model, ratings and configuration must be matched before the evidence is used for an order.
  • This is a medium-voltage DFW cable box, not the 400 V DFW variants in the same source folder. Do not transfer its 25 kA rating to a low-voltage product.
  • There is no internal-arc test in the nine-item report summary. Do not add an IAC claim.
