Explosion-proof distribution box

Explosion-proof distribution boxes are specialized enclosures designed to safely distribute electrical power in hazardous areas, compliant with EN, ATEX, and IECEx standards.

Key Features

Materials and Construction: These boxes are typically made from 304 or 316L stainless steel, Q235 steel, aluminum, or polyester, providing durability and corrosion resistance. They often feature hinged doors and specialized joints to maintain flameproof integrity during operation and maintenance . Protection and Certification: Explosion-proof distribution boxes are certified for Zone 1 and Zone 2 hazardous areas, with protection types including Ex d (flameproof), Ex e (increased safety), and Ex tb (dust-proof). They comply with EN standards and international certifications such as ATEX and IECEx . Electrical Features: These boxes can house air circuit breakers, leakage protection devices, and alarm systems. They support single-phase and three-phase outputs, with channels ranging from 1 to 12. Temperature control can be digital or via thermostats, and IP protection levels typically range from IP54 to higher, ensuring resistance to dust and water ingress . Customization and Modularity: Many models allow modular installation, enabling combination of multiple boxes to save space and meet specific distribution requirements. Custom solutions are available for cable entry, gland types, and internal layout, especially for oil, gas, and chemical industries .

Applications

Explosion-proof distribution boxes are used in industrial plants, oil and gas facilities, chemical processing units, and any environment with combustible gases or dust. They ensure safe power distribution, control, and monitoring in hazardous zones, preventing ignition of flammable atmospheres .
