Flameproof TypeSafecalledIsolationEliminateexplosionType，mainlyThroughCabinet Body的FlameproofAspectsAdvanced explosion-proof。The explosion-proof standard has strict parameter requirements for the length, gap, and roughness of flameproof surfaces. Only when all three meet the standard simultaneously can the flameproof effect be achieved.。

This box also has flanges and flameproof joints on all sides, but looking at the gap between the door and the body, the opening indicated by the arrow is large enough that it completely fails to meet the requirement of a gap ≤0.2mm. When an explosion, electric spark, or arc occurs inside the enclosure, it will immediately propagate to the outside of the enclosure, making this a non-conforming product.
