    Explosion-proof boxes KSRV-M made of mild steel

    Explosion-proof boxes KSRV-M made of mild steel Explosion-proof boxes KSRV-M made of mild steel - image 2 Explosion-proof boxes KSRV-M made of mild steel - image 3

    Product Description

    The KSRV-M explosion-proof terminal box with Ex e/Ex i protection is made of mild steel. It is used for switching, distributing, and connecting electrical circuits in hazardous areas of mines, quarries, and underground workings. The Ex e protection principle prevents sparks and overheating, while the Ex i components installed inside ensure intrinsic safety of internal circuits. 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.
    • Terminal boxes KSRV-M are included in the register of Russian industrial products.

    Additional information

    All KSRV-M explosion-proof enclosure covers, except for the KSRV-M111109 and KSRV-M171109, are supplied with hinges by default. Using hinged covers improves ease of installation, cable and wire connections, and subsequent maintenance.

    External and internal stainless steel grounding cluminaires can be connected to a terminal block mounting rail, mounting plate, or grounding busbar. Grounding for cable glands is ensured through contact with the enclosure wall, eliminating the need for additional grounding continuity measures.
