Dimensions of Waterproof Distribution Box Signage

Waterproof distribution boxes typically range from compact 4-way enclosures to larger 36-way units, with dimensions varying by series and manufacturer, often designed to meet IP65–IP66 standards for outdoor use.

Typical Dimensions and Configurations

• Compact Boxes (AT Series / 4–8 ways): Designed for tight spaces, these boxes often measure approximately 200–300 mm in height, 150–250 mm in width, and 80–120 mm in depth, suitable for small residential or commercial installations .
• Medium Boxes (HT Series / 8–16 ways): Provide extra internal room for DIN rail mounting and multiple terminals. Dimensions typically range 300–450 mm height, 250–350 mm width, and 120–180 mm depth, allowing cleaner cable routing and integration with fuses, SPDs, or breakers .
• Large or Modular Boxes (SHPN / 36-way): Used for industrial, photovoltaic, or high-capacity applications. These enclosures can exceed 600 mm in height, 400 mm in width, and 200 mm in depth, with customizable internal layouts, wall thickness, and knockout positions for cable entry .

Material and Protection

• Housing Materials: ABS for cost-effective indoor use; UV-stabilized polycarbonate (PC) for outdoor, solar, or marine exposure .
• Ingress Protection: IP65 ensures protection against dust and low-pressure water jets; IP66 adds resistance to powerful water jets, suitable for high-exposure environments .

Signage and Labeling Considerations

• Front Panel: Transparent PC covers allow visibility of internal circuits and labeling without opening the box .
• Custom Signage: Many manufacturers offer RAL color matching and custom labeling options to match project or brand requirements .
• Internal Layout: DIN rail configurations and multi-layer designs support clear signage for circuit identification, grounding, and safety instructions .

Summary

Waterproof distribution boxes are available in a wide range of sizes, from compact 4-way units to large 36-way enclosures. Dimensions depend on the series, number of circuits, and intended application, with IP65–IP66 ratings ensuring outdoor durability. For precise signage placement, it is recommended to consult the manufacturer's datasheet or installation diagram for the specific model, such as the HT-8 or EKDB10 series .
