FAQs
The HBA46571HR is designed for hazardous/classified locations with an IP66 rating and a NEMA 4 enclosure. It supports through-feed wiring via two 1/2" NPT hubs and operates on 120–277 Vac at 50/60 Hz. For retrofit projects, ensure wiring conforms to NEC/CEC requirements and that mounting feet align with four-foot fixtures in the Pauluhn Apex family.
Yes. The fixture uses standard 4 ft Pauluhn Apex form factor with through-feed wiring and quick-release features, facilitating straightforward integration into existing layouts. Verify alignment with compatible mounting hardware, lamp type (T5HO mini bi-pin), and through-feed junctions to maintain consistency with current configurations and minimize retrofit risk.
Ideal for chemical processing, mining, offshore platforms, and other areas classified as hazardous or restricted. The IP66 and NEMA 4 ratings, combined with a 4 ft, 6-lamp, 54W configuration, provide robust illumination while resisting dust, moisture, and corrosive wash-downs typical of demanding industrial facilities.
The quick-release feature enables fast lamp changes and access without extensive disassembly, reducing downtime during routine maintenance or lamp-lumen maintenance cycles. This translates to higher operational uptime, lower labor costs, and predictable maintenance scheduling in continuous-operation facilities.
The fixture is certified for Hazardous/Classified Locations, with NEC/CEC conformity, IP66 ingress protection, and a NEMA 4 enclosure. It is suitable for Class I, Division 2 and Class II, Division 1 environments, among other hazardous-area classifications, ensuring regulatory compliance across industrial markets.
