Eaton Specification Sheet - HBAB43571
Hazardous area rating and NEC/CEC compliance provide regulatory confidence and safer operations in chemical plants, refineries, and mining sites. This translates to reduced risk of non-compliance penalties and improved worker safety, enabling smoother project approvals and ongoing maintenance. IP66 protection and NEMA 4 construction guard against dust and water ingress, lowering replacement costs and downtime in washdown environments, outdoor facilities, or dusty production floors. The 54W, 4 ft length with a 3-lamp configuration utilizes T5HO mini bi-pin lamps for efficient light output and energy savings, supporting lower operating costs and consistent illumination across large workspaces. Aluminum housing and acrylic lens deliver rugged, corrosion-resistant performance, while the through-feed design and 1/2" NPT hubs enable flexible mounting and wiring options to fit legacy conduits and new builds alike. This fixture is well-suited for retrofit projects where dependability and compliance are critical, helping facilities maintain uptime without sacrificing safety.
