IP68 Electrical Enclosure Rating
IP68 electrical enclosures offer reliable protection against solid objects and water splashes.
What is IP68 Enclosure Rating?
IP68 electrical inclosures are intended to provide the most comprehensive protection for electrical equipment against dust and prolonged immersion in water. These inclosures are excellent for the most demanding indoor and outdoor applications, where exceptional protection is required.

A IP68 Enclosure For Your Application
Some of the basic types of IP68 electrical enclosures that you’ll find on the market today include:
IP68 electrical enclosures are rated for continuous immersion — equipment that lives underwater or in flood zones: submersible pump connections, wet-well controls, underwater lighting junctions, dockside and marine instrumentation, and any installation where standing water is a design condition rather than an accident. Under IEC 60529, IP68 means the ingress of water in harmful quantity is prevented during prolonged immersion at conditions agreed between manufacturer and user.
We build IP68 enclosures with welded or molded bodies, engineered seals, and entry systems that keep the rating after cabling. ElectricalCabinet has built electrical enclosures and control systems since 2010, delivering more than 4,000 projects for industrial clients. Our fabrication covers CNC punching, bending, and welding, with custom cutouts, sizes, and surface finishes built to your drawings. The cable entries and potting details are specified together with the box — immersion duty is won or lost at the glands, not the shell.
Features of IP68 Enclosure
- Ingress Protection (IP) Rating: The "IP" in IP68 refers to Ingress Protection, and the "68" represents the level of protection. The first digit, "6", denotes total dust protection. The second digit, "8", denotes protection against prolonged immersion in water deeper than one metre, as stated by the manufacturer.
- Dust Protection: IP68 enclosures provide comprehensive dust protection, guaranteeing that dust does not enter the enclosed equipment.
- Water Protection: These enclosures provide strong protection against continuous immersion in water, making them appropriate for locations where equipment may be subjected to extended submersion.
- Construction: These enclosures are often made of robust materials such as stainless steel, aluminium, or reinforced plastic, and are meant to endure the worst weather conditions while providing long-term protection.
Advantages And Disadvantages For IP68 Enclosure
Advantages
- Comprehensive Protection: Offers the best degree of protection against both dust and continuous water immersion, therefore guaranteeing the lifetime and operation of the contained machinery.
- Versatile Use: Suitable for a broad spectrum of uses in both indoor and outdoor locations, in the most demanding surroundings is adaptable use
- Durable Construction: Designed from strong materials to resist great environmental exposure and offer long-lasting protection, durable construction.
Disadvantages
- Cost: IP68 enclosures' great degree of protection and sturdy construction means that they might be more costly.
- Installation Considerations: Maintaining the IP68 certification and guaranteeing complete protection depends on correct installation.

Frequently Asked Questions
What exactly does the 8 in IP68 guarantee?
It guarantees protection against continuous immersion in water under conditions — depth and duration — agreed between manufacturer and user, unlike the defined-jet tests of IP65/IP66. Always confirm the specific depth/time specification behind an IP68 claim.
IP68 or IP69 — which do I need?
IP68 targets immersion; IP69 targets high-temperature, high-pressure wash-down. Submerged equipment needs IP68; food-line equipment facing steam-jet cleaning needs IP69K-class performance. Our comparison guide covers the boundary cases.
Why do IP68 enclosures fail in service?
Almost always at cable entries and unsealed penetrations drilled on site. We machine and re-seal all cutouts in the factory and match glands to the actual cable schedule — site-drilling an IP68 box voids the immersion rating.
Can electronics be serviced inside an IP68 enclosure?
Yes — the lid seals are designed for repeated opening when correctly reassembled. We supply torque and gasket-lubrication instructions, and recommend spare gaskets for maintenance cycles.
