EJB241808
Quick Summary
EJB241808 junction box delivers rugged enclosure protection for hazardous-location installations in industrial plants. Operators and maintenance teams struggle with oversized, non-compliant boxes that slow wiring, increase inspection cycles, and elevate safety risk. This enclosure delivers NEC/CEC compliance, IP66 ingress protection, and multiple NEMA ratings to meet stringent standards across Class I, Division 1 & 2 and Class II environments. With copper-free aluminum construction and a generous internal cavity, it reduces weight relative to steel yet remains exceptionally durable for outdoor, washdown, and chemical exposure scenarios. The Style C, without hinge design simplifies field mounting and service access, accelerating installations and minimizing downtime. For engineers driving uptime and compliance, this model offers a reliable, long-term enclosure solution.

The 24 x 18 x 8 inch enclosure footprint provides ample interior space for complex terminations and layout, reducing the need for multiple boxes and simplifying thermal management in hazardous-location control panels. Copper-free aluminum delivers corrosion resistance with a lighter overall profile than traditional steel housings, lowering handling risk and maintenance costs while maintaining durable protection in chemical processing and offshore environments. IP66 ingress protection guards against dust and water ingress in washdown and outdoor installations, supporting reliable operation in demanding plants and outdoor sites where exposure is common. The NEC/CEC compliance and multiple recognized NEMA ratings (3, 3R, 4, 7, 9) establish a clear path to regulatory acceptance, reducing project risk and accelerating commissioning. Style C without hinge streamlines installation and service access, minimizing field labor and downtime during upgrades or retrofits. The enclosure’s large interior accommodates diverse termination methods and mounting arrangements, enabling faster engineering sign-off and reduced engineering change orders. Availability of CAD drawings, SP3D design packages, and installation instructions from Eaton enhances project planning, enabling precise fit and faster site deployment in FIFO or modular panel builds. In real-world terms, these features translate into fewer field errors, shorter commissioning windows, and lower total cost of ownership for hazardous-location electrical infrastructure.

FAQs
The EJB241808 is designed for hazardous locations and supports NEC/CEC compliance with Class I, Division 1 & 2 and Class II, III ratings. When installing, verify appropriate seals, mounting orientation, and cable entry selections to maintain IP66 protection. Utilize the provided installation sheets and CAD drawings to ensure correct gasket seating, proper enclosure alignment, and safe terminal access during commissioning.
Key ratings include IP66 ingress protection and NEMA ratings 3, 3R, 4, 7, 9. It is certified for hazardous locations per NEC/CEC guidelines, suitable for Class I Div 1 & 2 and Class II Div 1 & 2 environments, as well as Zone 1 & 2 classifications. These certifications support compliance in chemical plants, oil & gas facilities, and other demanding industrial settings.
Yes. Eaton provides 3D CAD drawing packages, SP3D design packages, and installation instructions (IF 931) to streamline design, integration, and field installation. This enables precise fit checks, faster routing of terminations, and reduces on-site errors. Access to these resources helps maintain project schedules and ensure accurate panel layouts.
Absolutely. The enclosure is copper-free aluminum with IP66 protection, designed for harsh outdoor and washdown conditions common in chemical, water treatment, and oil & gas facilities. Its corrosion resistance and rugged construction help maintain long-term reliability, even under exposure to moisture, dust, and chemical cleaners.
The enclosure size is 24 x 18 x 8 inches, with a weight around 302 pounds. When planning handling and mounting, account for the weight in crane or forklift operations and ensure the mounting surface can support long-term loads. The large interior volume also informs cable routing and termination space requirements for compliant, clean wiring.
