SHORV-MT Mild Steel Explosion-Proof Boxes

Product Description

The SHORV-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 of mines, quarries, and underground workings. 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.
Reliable protection against dust and moisture IP66/IP67/IP68.
Terminal boxes SHORV-MT are included in the register of Russian industrial products.
