Eaton Specification Sheet - HPAB42570
Durable IP66 enclosure and hazardous-location rating protect internal components against dust, water, and washdowns. This reduces uptime loss from ingress and simplifies maintenance in harsh environments. It’s specifically suited to Class I Division 2 locations and similar classifications, enabling compliant operation in chemical plants, oil refineries, and offshore facilities. 4 ft lamp length with two lamps and T5HO mini bi-pin lamps delivers high-quality illumination and consistent color across large workfaces. Business impact includes improved operator visibility and reduced replacement cycles due to longer lamp life. Applications span plant floors, corridors, and equipment bays where reliable lighting is essential to safety and productivity. Pendant mounting and bolted-door access simplify installation and servicing in restricted spaces. The 1/2 inch entry with two NPT hubs supports flexible conduit routing and wiring options, reducing installation time and wiring complexity for new builds or retrofits. Universal voltage 120-277 VAC and 50/60 Hz support minimizes stock diversification and simplifies maintenance across multiple facilities. This compatibility also helps reduce total cost of ownership by allowing a single fixture to serve global operations and varying supply conditions. Aluminum housing and acrylic lens combine durability with easy handling, resisting corrosion and impact in demanding environments. The 54W lamp configuration provides ample brightness while keeping energy use economical, aligning with energy targets and code-required lighting levels in hazardous locations. Compliance and installation resources are readily accessible, with official Eaton installation sheets and specification documents informing safe, code-compliant commissioning and ongoing maintenance.
