The EPJ505B504 is engineered as an explosion-proof conduit outlet box, delivering robust protection for hazardous process environments. The IP66 and NEMA 4X ratings ensure water, dust, and chemical ingress are controlled, minimizing field failures and guarding wiring in harsh plants. This enclosure is designed for Class I and Class II hazardous locations (Division 1 and 2), supporting NEC/CEC compliance across global projects. Brass construction provides exceptional durability and corrosion resistance in corrosive atmospheres common in oil, gas, and chemical processing. The material choice also aids heat dissipation and sealing, contributing to longer service intervals and reduced maintenance costs. Installed as part of Pauluhn EPJ505 series solutions, it aligns with industry standards while delivering dependable performance. It features four 1/2 inch trade entries, enabling flexible wiring configurations in compact control panels. The surface-mount mounting style simplifies installation on walls, enclosures, or equipment frames and supports reliable gasketing for sealed operation. Users gain faster field terminations and fewer penetrations, cutting project timelines and reducing labor costs. The enclosure's compact footprint—5.69 in length, height, and 3.5 in width with a 9.7 lb weight—fits into tight spaces without sacrificing protection. The 1/2 inch trade size is a common standard, ensuring compatibility with standard conduit fittings and simplifying stocking of spare parts. Its rugged build reduces risk of equipment downtime in harsh environments. From installation instructions to specification sheets, Eaton offers authoritative resources to support compliance and proper use, including the EPJ505 catalog page and LBL1514 instruction sheet.
