Eaton Specification Sheet - HBAB43574
Aluminum housing with an acrylic lens delivers rugged durability and reliable ingress protection. The result is reduced maintenance cycles and lower replacement costs in harsh environments such as chemical plants and offshore facilities. Three-lamp 54W T5HO mini bi-pin configuration provides high lumen output with efficient energy use. Compared with legacy ballast-driven lighting, this fixture reduces operating costs while delivering consistent color and brightness in work cells and walkways. Through-feed mounting with two 3/4 inch NPT hubs and bolted-door access simplifies field installation and service, enabling faster commissioning and safer maintenance in constrained spaces. Wide voltage range of 120-277 VAC and 50/60 Hz compatibility supports flexible power supply across facilities, reducing inventory variety. NEC/CEC compliance and hazard ratings ensure regulatory alignment and safer operation across demanding industrial environments.

FAQs
HBAB43574 supports through-feed wiring with a bolted-door enclosure and two 3/4 inch NPT hubs for secure, flexible installation in confined hazardous spaces. The 4 ft, 3-lamp configuration accelerates commissioning and simplifies wiring because it can be wired for 120-277 Vac without ballast changes. This makes retrofits and new builds quicker and safer in challenging environments.
HBAB43574 carries NEC/CEC compliance and hazard ratings essential for regulated facilities. It supports Class I, Division 2; Class II, Division 1; and Class III locations, along with a NEMA 4 rating and IP66 ingress protection. These certifications help you meet local codes, minimize risk during audits, and avoid costly retrofit work after installation.
Electrical specs include 120-277 Vac input, 50/60 Hz operation, and a 54W total wattage across three lamps in a 4 ft length using a T5HO mini bi-pin configuration. The fixture is designed for through-feed wiring with entry via two 3/4" NPT hubs, ensuring reliable performance and broad compatibility with standard industrial power systems.
HBAB43574 excels in chemical processing plants, refineries, mining operations, wastewater treatment facilities, and offshore rigs. Its rugged build and hazardous-location ratings ensure reliable illumination in damp, dusty, and high-risk environments, while the through-feed wiring and long lamp life reduce downtime during maintenance cycles and support safer, more productive work cells.
The fixture’s aluminum housing resists corrosion and the acrylic lens minimizes impact damage, reducing service calls. IP66/NEMA 4 protection and hazardous-location ratings help avoid unnecessary shutdowns. Although initial cost may be higher than non-rated fixtures, lifecycle savings come from lower energy use, extended lamp life, and simplified, safer servicing in harsh environments.
