Specifications and Models of Waterproof Distribution Box

Waterproof distribution boxes are IP65–IP68 rated enclosures designed to protect electrical circuits from water, dust, and UV exposure, available in multiple series and configurations for industrial, commercial, and outdoor applications.

Key Specifications

• Ingress Protection (IP Rating): Most waterproof distribution boxes are rated IP65 to IP68, ensuring protection against dust and water jets, with some models capable of temporary immersion in water up to 1 meter for 30 minutes (IEC 60529) .
• Materials: Commonly made from ABS or polycarbonate (PC) plastics, offering UV resistance, mechanical strength, and lightweight durability for field installations .
• Flammability: Housing plastics are evaluated per UL 94 standards for fire safety .
• Mounting Options: Many boxes support DIN rail mounting for MCBs, RCDs, RCBOs, and other modular components .
• Layers and Ways: Available in single, double, or triple layers, with module counts ranging from 4 to 39 ways, suitable for lighting, control circuits, solar PV, and industrial applications .
• Sealing: Compression gaskets maintain waterproofing even after repeated openings, and knock-out entries support cable glands for secure connections .
• Standards Compliance: Designed to meet IEC 60529, IEC 60695-2-10, IEC 62262, and often CE/TUV certified .
