EU Explosion-proof Distribution Box Control Box

EU explosion-proof distribution and control boxes are ATEX and IECEx certified enclosures designed for safe operation in hazardous areas, available in stainless steel, aluminum, or polyester, and fully customizable to meet industrial requirements.Overview

Explosion-proof distribution boxes and control boxes are essential for electrical systems in hazardous areas where flammable gases, vapors, or dust may be present. In the EU, these devices must comply with the ATEX directive, ensuring safe operation in potentially explosive atmospheres, with many also meeting IECEx international standards for global use .

Materials and Construction
  • Stainless Steel (AISI 304L / 316L): Offers high corrosion resistance and durability, suitable for extreme temperatures and outdoor conditions .
  • Aluminum: Lightweight, corrosion-resistant, and suitable for marine or offshore applications .
  • Polyester / GRP: Non-metallic, flexible, and configurable for various sizes and terminal arrangements . Enclosures are designed with robust flameproof joints, specialized hinges, and modular internal layouts to accommodate meters, switches, relays, PLCs, and other control devices .
Certifications and Hazard Zones
  • ATEX and IECEx certified for Zones 1, 2, 21, and 22, covering areas with combustible gases or dust .
  • Flameproof types include Ex d IIB+H2, suitable for high-risk environments .
  • Some models also carry UL, TR CU, NEPSI, and other international certifications, ensuring global compliance .
Features and Customization
  • Modular design allows custom configuration of control elements, meters, and actuators .
  • Up to four contact elements can be mounted under a single actuator, saving space .
  • Optional accessories include cable glands, breathing glands, flanges, and locking devices .
  • Enclosures can withstand ambient temperatures from –40 °C to +70 °C, suitable for extreme climates .
  • Customizable internal layouts allow integration of MCCBs, MCBs, AC contactors, soft starters, frequency converters, and monitoring instruments .
Applications

These boxes are widely used in:

  • Industrial automation and motor control
  • Oil & gas, chemical, and petrochemical plants
  • Offshore and marine installations
  • Hazardous area lighting and power distribution
Leading Manufacturers
  • Atex Delvalle: Offers stainless steel and GRP enclosures with fully configurable local control stations .
  • ROSE Systemtechnik: Provides aluminum, polyester, and stainless-steel control stations for explosion-prone zones .
  • R. STAHL: Modular 8150 series local control stations with extensive customization and international certifications .
  • Pepperl+Fuchs: EJB series aluminum Ex d control and distribution panels for industrial and offshore applications . These solutions ensure maximum safety, flexibility, and compliance for EU and international hazardous area installations.
