Brass construction delivers robust corrosion resistance in challenging environments, reducing downtime and replacement costs for chemical plants and offshore facilities. This translates to longer service life for terminations and connectors and lower total cost of ownership in aggressive atmospheres. The IP66 and NEMA 4X ratings protect against dust ingress and water exposure, ensuring reliable operation in wash-down areas and outdoor installations while maintaining compliance with industrial safety standards. Explosion-proof design for hazardous locations provides peace of mind in Class I/II environments, enabling safer wiring in oil & gas, mining, and chemical processing facilities with fewer enclosure-related contingencies. The 3/4" trade size and two entry points with 180° conduit openings offer flexible routing and easier field wiring, reducing installation time and improving first-pass accuracy. Surface mounting simplifies mounting logistics, cutting labor, while the 4-pole 20A terminal block supports robust electrical connections with fewer terminals to manage, lowering maintenance complexity. At 9.8 lb with dimensions of 5.69 in by 5.69 in by 3.5 in, this enclosure fits compact spaces without compromising protection or accessibility, aiding shipping and on-site handling in busy plant environments. Industry-grade compatibility with Pauluhn style accessories and Eaton catalog pages further streamlines procurement and project planning, aligning with long-cycle projects and multi-site deployments.

FAQs
Installation should follow the EPJ505B752T4 specifications for surface mounting in hazardous locations. Ensure a compliant mounting surface, verify that conduit entries are oriented per 180° apart, and secure the box using appropriate hardware. Route cables through the 3/4" conduits and connect to the 4-pole, 20A terminal block with proper torque per Eaton instructions. Review NEC/CEC requirements for Class I/II locations, maintain IP66/NEMA 4X integrity, and consult the IF LBL 1514 installation sheet for step-by-step guidance tailored to explosion-proof enclosures.
The EPJ505B752T4 features a 3/4" trade size, two entries, and a 4-pole, 20A terminal block. This configuration supports reliable terminations for up to 20A circuits with compact wiring in hazardous environments. The brass, IP66/NEMA 4X enclosure maintains integrity against dust and water ingress, enabling safe operation in demanding conditions. When designing wiring, plan for two entry points, ensure proper conduit routing, and observe torque values from the Eaton specification sheet to prevent terminal loosening under vibration.
Yes. The EPJ505B752T4 is rated for hazardous locations, with NEC hazardous ratings including Class I, Division 1 and Division 2, and Class II, Division 1 and Division 2. This makes it appropriate for oil and gas facilities and similar environments where explosive atmospheres may be present. The enclosure also carries IP66 and NEMA 4X ratings to protect against dust, water ingress, and corrosion, supporting long-term reliability in challenging sites.
The EPJ505B752T4 meets NEC/CEC standards and hazardous-location classifications (Class I/II divisions), with NEMA 4X and IP66 ratings. Area classification is Hazardous/Classified Locations. These certifications help ensure regulatory compliance for installations in petrochemical, mining, and chemical processing facilities, facilitating inspections and approvals. Always reference the Eaton catalog page and the EPJ505 datasheet for the most current certification statements and installation guidance.
Using the EPJ505B752T4 can reduce maintenance downtime due to its robust brass construction and high ingress protection (IP66) along with NEMA 4X corrosion resistance, lowering replacement frequency in harsh environments. Its two-entry design and 4-pole 20A terminal block simplify wiring, reducing field labor time during upgrades. Over multi-year operations, these factors translate to lower total cost of ownership, fewer unplanned outages, and improved system reliability in hazardous-location installations.
