    KKVA-MT Series Mining Terminal Boxes

    KKVA-MT Series Mining Terminal Boxes

    Product Description

    The KKVA-MT is an explosion-proof terminal box with Ex d protection rating made of mild steel. It is used for switching, distributing, and connecting electrical circuits in hazardous areas. The explosion-proof enclosure reliably contains any spark or explosion within the enclosure, preventing ignition of the external environment. It ensures easy installation and maintenance.

    Advantages

    • Certified equipment ensuring safety and uninterrupted operation.
    • Corrosion resistance and durability - polymer-epoxy coating protects against aggressive environments.
    • Mild steel body designed to withstand the extreme conditions of underground mines and workings.
    • Flat connection of the box cover, eliminating the risk of “biting” the threaded connection
