    KSRV-N Stainless Steel Explosion-Proof Junction Boxes

    KSRV-N Stainless Steel Explosion-Proof Junction Boxes Explosion-proof junction boxes type KSRV-N made of stainless steel - image 2

    Product Description

    The KSRV-N explosion-proof terminal box with Ex e/Ex i protection type is made of stainless steel. It is used for switching, distributing, and connecting electrical circuits in hazardous areas. The Ex e protection principle prevents sparks and overheating, while the Ex i components installed inside ensure intrinsic safety of the internal circuits. It ensures easy installation and maintenance.

    Advantages

    • Certified equipment ensuring safety and uninterrupted operation.
    • The body is made of stainless steel, resistant to aggressive environments, alkalis, sulfuric and hydrochloric acids.
    • Double-sided electrochemical polishing ensures a durable and aesthetic appearance.
    • Certified for food, oil and gas, chemical, marine and mining applications.
    • Terminal boxes KSRV-N are included in the register of Russian industrial products.
