FAQs
Installers should plan for through-feed wiring using the two NPT hubs and ensure the supply is within the 120–277Vac range at 50/60 Hz. The bolted-door design requires access for maintenance, and the fixture must be mounted per NEC/CEC guidelines for Class I, II, and III environments. Clearances and enclosure integrity must meet hazardous-location requirements before energizing.
HBAB43574P delivers 54W total across three lamps with a 4 ft length, using T5HO mini bi-pin lamps. It operates on 120–277 Vac at 50/60 Hz, enabling flexible integration with common plant power systems and reducing the need for multiple drivers. This supports simplified panel design and inventory management while maintaining reliable luminance in hazardous areas.
Yes. The fixture is rated IP66 and built with an aluminum housing and polycarbonate lens, providing strong resistance to dust, water jets, and wash-down conditions. This makes it well-suited for outdoor installations, chemical plants, refineries, and other harsh environments where wash-down capability and durability are critical.
HBAB43574P complies with NEC/CEC standards and offers hazardous-location ratings for Class I Division 2, Class II Division 1, and Class III, along with a NEMA 4 enclosure and IP66 protection. These certifications help meet stringent regulatory requirements for hazardous and classified locations across multiple industries.
The bolted-door access, through-feed wiring, and two NPT hubs simplify maintenance wiring and servicing. Durable IP66/NEMA 4 protection reduces downtime from environmental exposure and corrosion, while the 3-lamp, 54W configuration lowers energy use and lamp replacement frequency. Together, these features translate to lower total cost of ownership and improved uptime in hazardous locations.
