Explosion-Proof ISOLATORS

Explosion-proof isolators are specialized switches designed to provide absolute electrical isolation in hazardous environments where explosive gases, vapors, or dust may be present—such as petrochemical plants, offshore platforms, sewage treatment facilities, and industrial processing zones. At Liya Qatar, we proudly supply top-of-the-line explosion-proof isolators from industry-leading brands SCAME and Eaton, ensuring safe and reliable operation in the most demanding conditions.

What Are Explosion-Proof Isolators?

Explosion-proof isolators are rugged isolating devices that safely disconnect electrical circuits, preventing the ignition of hazardous atmospheres. Designed to maintain integrity under extreme conditions, they ensure electrical circuits can be shut down safely, protecting both personnel and equipment. These units meet strict certifications—such as ATEX, IECEx, UL, and FM—making them ideal for Zone 1, Zone 2, Zone 21, and Zone 22 classified hazardous areas.
