FAQs
SPA43170 is a through-feed 4 ft fixture with 3/4" entry and (2) hubs, supporting universal 120-277 VAC operation at 50/60 Hz. Plan conduit routing to align with NEC/CEC requirements for Hazardous/Classified Locations, and ensure access for maintenance. Use hazloc-rated wiring methods and verify Class I Division 2 (and related) classifications are in scope for your area. This configuration enables flexible retrofit and clean wiring runs in tough environments.
SPA43170 uses a 3-lamp, 4 ft fluorescent arrangement with a total of 32W. It operates on 120-277 VAC at 50/60 Hz and uses T8 bi-pin lamps. The lumen output per fixture, combined with durable housing and polycarbonate lens, supports longer service intervals and lower maintenance costs. Standard ballast compatibility and common component availability help reduce replacement parts downtime and overall lifecycle costs.
Yes. SPA43170 is designed for hazardous/classified locations with NEC/CEC compliance, IP66 ingress protection, and a NEMA 4 enclosure. This makes it suitable for chemical plants, oil and gas facilities, refineries, mining, and other harsh environments where reliable lighting and robust enclosure protection are essential to maintain safety and uptime.
The fixture carries NEC/CEC standards for Hazardous/Classified Locations, a NEC hazardous rating of Class I, Division 2 (and Class II, Division 2, Class III), IP66 ingress protection, and a NEMA 4 enclosure. These certifications support safe operation in demanding environments and simplify the design-compliance process during project approvals.
The 32W three-lamp design delivers energy efficiency for 4 ft runs, while the rugged aluminum housing and matte polycarbonate lens reduce wear and cleaning costs. IP66 and NEMA 4 protections lower ingress-related maintenance frequencies. Combined with familiar 120-277 VAC operation, this translates to lower downtime, fewer replacement parts, and a favorable total cost of ownership over the fixture’s life.
