A three-level distribution box designed for outdoor use is typically made of steel, rainproof, and suitable for temporary construction site power setups.

Key Features

Material and Construction: Most three-level distribution boxes are made from cold-rolled steel plates, providing durability and resistance to outdoor conditions. The cabinets often feature a sloping roof design and reinforced triangular brackets to prevent water accumulation and enhance stability . Rainproof Design: The rainproof feature is achieved through a roof-type structure and thickened brackets, which protect internal components from rain and reduce the risk of rusting . Some models are also labeled as waterproof or outdoor portable, suitable for industrial and construction environments . Internal Configuration: These boxes are usually empty, allowing for flexible installation of air circuit breakers and other electrical components. Common protective devices include 2P/32A, 3P/63A, 3P/10A, and 100A breakers, which can accommodate various power requirements . Applications: Ideal for temporary power supply on construction sites, including steelwork, woodworking machinery, rebar areas, bending machines, cutting machines, lighting sockets, and power tools . They are also suitable for industrial and municipal projects requiring a safe and organized power distribution solution . Portability and Safety: Some models are mobile and portable, making them convenient for temporary setups. The triangular bracket structure ensures stability, while rear wiring configurations improve safety and organization . Certifications and Quality: Reputable manufacturers often provide ISO9001 certification and comply with international standards such as CE, RoHS, KEMA, CB, and TUV, ensuring product reliability and safety .

Summary

A three-level empty distribution box with rainproof features is a robust solution for outdoor and construction site power distribution. Its steel construction, waterproof design, flexible internal configuration, and safety features make it suitable for temporary or industrial electrical setups, providing both durability and protection against environmental factors .
