Product Description

The KKVA explosion-proof terminal box with Ex d protection is made of aluminum alloy with alloying modifiers. 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.
Compact size and easy installation.
The aluminum housing shell combines exceptional mechanical strength, corrosion resistance and efficient heat dissipation.
KKVA terminal boxes are included in the register of Russian industrial products.
