Level 2 distribution box equipped with explosion-proof plug

A Level 2 distribution box equipped with an explosion-proof plug is designed for hazardous areas, offering robust stainless steel construction, ATEX/IECEx certification, and flexible component integration.Key Features

Construction and Materials: These distribution boxes are typically made from 316L or 304 stainless steel, providing high corrosion resistance and durability in extreme environments . Some models also use aluminum alloy with electrostatic spraying for lightweight applications . Explosion-Proof Certification: Boxes are certified for ATEX and IECEx, suitable for Zone 1 and Zone 2 hazardous areas. They comply with flameproof standards (Ex d) and dust protection (Ex tb) to prevent ignition of flammable gases or dust . Internal Components: They can be equipped with a wide range of electrical components, including air circuit breakers, MCBs, MCCBs, contactors, relays, fuses, meters, and control switches. Level 2 boxes often allow modular installation, enabling multiple control elements under a single actuator and flexible internal layouts . Explosion-Proof Plug: The plug is designed to maintain the integrity of the flameproof enclosure, preventing sparks or arcs from escaping. Specialized hinge structures protect flameproof joints during opening and closing, prolonging service life . Customization and Installation: Many manufacturers offer customizable sizes, terminal arrangements, and component configurations to meet specific project requirements. Boxes can be combined or installed freely to save space and adapt to various distribution systems . Environmental Performance: These boxes are engineered to withstand extreme temperatures (as low as –40°C), outdoor conditions, and maritime environments, ensuring reliable operation in harsh industrial settings . Protection Level: Typical protection ratings include IP54 or higher, ensuring resistance to dust and water ingress .

Applications
  • Industrial plants with flammable gases or dust
  • Oil and gas facilities
  • Chemical processing units
  • Hazardous area electrical distribution and control systems
Summary

A Level 2 explosion-proof distribution box with plug combines robust stainless steel construction, ATEX/IECEx certification, flexible internal configuration, and specialized explosion-proof plugs to ensure safe and reliable electrical distribution in hazardous environments. These boxes are highly customizable, durable, and suitable for both indoor and outdoor industrial applications .
