Cost of Custom Waterproof Distribution Boxes

The price of a custom-made waterproof distribution box varies widely depending on size, material, IP/NEMA rating, and customization, typically ranging from $50 to several hundred dollars per unit, with bulk orders reducing per-unit cost.

Factors Affecting Price

  1. Material: Boxes can be made from metal (stainless steel, aluminum), PC/ABS plastic, or polycarbonate, with metal enclosures generally costing more due to durability and corrosion resistance .
  2. Waterproof Rating: Higher IP ratings (IP65–IP68) or NEMA standards (3S, 4X, 6P) increase cost because of enhanced sealing, gaskets, and construction quality .
  3. Size and Configuration: Larger boxes or those with DIN rail setups, multiple terminals, or modular compartments require more material and labor, raising the price .
  4. Customization: Features like OEM branding, knockouts, busbar fitment, UV stabilization, or pre-assembled kits add to the cost .
  5. Certifications: CE, UL, TUV, RoHS, and other certifications may increase manufacturing costs but ensure compliance and reliability .
  6. Order Volume: Wholesale or bulk orders reduce per-unit cost, while single custom units are more expensive .

Typical Price Range

  • Small plastic IP65 boxes: Approximately $50–$100 per unit
  • Medium-sized metal IP66/IP67 boxes: Around $150–$300 per unit
  • Large, fully customized enclosures with high IP/NEMA ratings: Can exceed $500 per unit, depending on complexity and certifications .

How to Get an Accurate Quote

Since prices vary significantly based on specifications, the best approach is to contact manufacturers directly:

  • Saipwell: Offers full custom metal enclosures with NEMA/IP ratings and certifications .
  • SinoBreaker: Provides IP65–IP68 plastic and DIN rail distribution boxes with pre-assembled options .
  • ZCEBOX: Specializes in IP65/IP66 waterproof boxes for industrial applications .
  • Selhot Electric: Factory-direct IP65/IP67 PC/ABS boxes with custom knockouts and certifications . Provide details such as dimensions, material, IP/NEMA rating, internal layout, and quantity to receive a precise quote. Bulk orders or repeat purchases often qualify for discounted pricing and faster production timelines.
