There are several series of distribution boxes

Distribution boxes come in multiple series and types, including indoor/outdoor, metal/plastic, wall-mounted/floor-standing, main and sub-distribution boards, modular smart boxes, and specialized industrial variants.Classification by Installation Environment
  • Indoor Distribution Boxes: Designed for protected environments such as homes, offices, and utility rooms. They are shielded from rain, dust, and extreme temperatures and are typically made of plastic or metal for safety and durability .
  • Outdoor Distribution Boxes: Built to withstand exposure to weather, sunlight, and dust. They require higher IP protection ratings and robust enclosures to ensure safety in open environments .
Classification by Material
  • Metal Distribution Boxes: Common in industrial and commercial applications, offering high mechanical strength, impact resistance, and long-term durability .
  • Plastic Distribution Boxes: Lightweight and corrosion-resistant, suitable for residential or light commercial use .
Classification by Mounting Method
  • Wall-Mounted Boxes: Installed on walls for easy access and space efficiency.
  • Floor-Standing Boxes: Larger enclosures for industrial or high-capacity applications, often housing multiple circuits and busbars .
Functional Series
  • Main Distribution Board (MDB): The primary control panel receiving high-voltage supply and distributing it to sub-distribution boards and major loads. Found in large commercial buildings, factories, and power plants .
  • Sub Distribution Board (SDB): Receives power from the MDB and distributes it to smaller circuits within a building or facility .
  • Meter Panels and Panel Fuse Banks: Used for metering and protection of individual circuits .
  • Unitized Panels and Consumer Units: Compact solutions for residential or small commercial applications, often including RCDs and circuit breakers .
  • Transfer Switches: Critical for facilities requiring backup power, allowing seamless switching between utility and generator supply .
  • Enclosed Switchgear: High-capacity, protective enclosures for industrial power distribution .
Specialized and Modular Series
  • Smart Distribution Boxes: Include energy monitoring units, communication modules, and smart circuit breakers for real-time data collection and integration with home automation systems .
  • Modular FieldPower® Series: Designed for decentralized power and signal distribution, supporting IP67 protection, pluggable connections, and flexible installation in industrial automation and sensor-actuator networks .
  • EX Zone Variants: Explosion-proof or robust versions for hazardous industrial environments .
Key Considerations for Selection

When choosing a distribution box, consider:

  • Installation environment (indoor vs outdoor)
  • IP protection rating for dust and water resistance
  • Number of circuits and electrical load
  • Material and mechanical strength
  • Functional requirements (e.g., smart monitoring, modularity, backup power integration) By understanding these series and classifications, you can select the appropriate distribution box for residential, commercial, or industrial applications, ensuring safety, efficiency, and long-term reliability .
