Marine Grade Rainproof Junction Box

Product features:

The core advantage of this marine-grade junction box is its 316 stainless steel construction, which offers superior resistance to saltwater corrosion, acid, and alkali, addressing the pain point of rapid enclosure degradation in marine settings. Its IP68 rating guarantees protection against full immersion in water, making it suitable for underwater equipment connections and splash zone electrical systems. The FKM sealing strip provides excellent resistance to oil, ozone, and saltwater, maintaining a tight seal even after years of exposure to harsh marine conditions. The UL94 V-0 flame retardant rating prevents fire spread in enclosed ship spaces, while the 1000-hour salt spray resistance ensures long-term durability. Additionally, it features heavy-duty mounting brackets for secure bulkhead or wall installation, withstanding strong ship vibrations and rough sea conditions. The box also includes corrosion-resistant stainless steel screws and hinges, ensuring easy access for maintenance without rusting.

Product specifications:

This marine-grade rainproof box measures 250mm (L) × 200mm (W) × 100mm (H) and weighs 4.2kg, providing a robust housing for marine electrical connections. The 316 stainless steel enclosure has a wall thickness of 2mm, offering high impact resistance up to IK10. The internal terminals are made of tin-plated copper, ensuring excellent electrical conductivity and corrosion resistance. The FKM sealing strip has a thickness of 4mm, creating a watertight barrier against saltwater and moisture. The box is certified by ABS, DNV, and CE, confirming compliance with global marine safety standards. Its rated voltage of 440V AC and current of 63A support marine electrical systems such as ship lighting, navigation equipment, and pump controls. The operating temperature range of -35°C to 80°C ensures functionality in cold polar waters and tropical climates, with vibration testing compliance to IEC 60068-2-6 for shipboard use.

Product application:

This specialized enclosure is designed for a wide range of marine and offshore applications. In commercial ships, it protects the wiring connections of navigation equipment, communication systems, and engine room controls, ensuring safe operation in rough seas and heavy rain. For offshore drilling platforms, it serves as a junction box for oil rig electrical systems, resisting saltwater corrosion and extreme weather conditions. In coastal ports and marinas, it protects the wiring of dock lighting, security cameras, and loading equipment, withstanding salt spray and tidal splashes. For fishing boats, it provides waterproof protection for fish finder systems and deck lighting, ensuring reliable operation in harsh ocean environments. Additionally, it can be used for marine research equipment, protecting the wiring of underwater sensors and data collection devices, as well as coastal renewable energy systems such as tidal power generators.
