FAQs
When installing HPAB44571 in hazardous locations, plan for through-feed wiring with 1/2" entry and two NPT hubs to simplify field connections. The bolted-door design allows quick access for lamp changes while maintaining enclosure integrity. Ensure power is within the 120-277 VAC range and adhere to NEC/CEC requirements for Class I, II, and III locations to maintain compliance and safety.
Yes. HPAB44571 is rated for Hazardous/Classified Locations with NEC/CEC compliance and hazardous ratings covering Class I, Division 2; Class II, Division 1; Class II, Division 2; and Class III. Its IP66 ingress protection and NEMA 4 enclosure provide the needed protection in these risk-prone environments, making it appropriate for many industry sectors.
The fixture operates on 120-277 VAC at 50/60 Hz and uses four lamps configured as 4-lamp T5HO mini bi-pin fluorescent units, totaling 54W. The acrylic lens and aluminum housing complement the fluorescent lamp technology by delivering reliable light output in demanding environments while maintaining energy efficiency.
Maintenance benefits include a bolted-door access for lamp changes and a through-feed wiring setup that simplifies field modifications. The IP66/NEMA 4 protection and corrosion-resistant aluminum housing reduce environmental wear, while the acrylic lens resists impact and chemical exposure, all contributing to longer service intervals and lower lifecycle cost.
