Key Considerations

• IP Rating: Choose IP65 for protection against rain and dust, IP66 for high-pressure water jets, and IP67 for temporary submersion.
• Material: ABS plastic is lightweight and corrosion-resistant; metal enclosures offer higher impact resistance.
• Size and Configuration: Select based on the number of circuits, DIN rail requirements, and internal space for wiring.
• Installation: Look for pre-drilled mounting holes, DIN rail compatibility, and gasketed covers for reliable waterproofing. By selecting from these sources, you can find a waterproof electrical distribution box that meets your environmental, safety, and installation requirements.
