FAQs
HBAB44174EM1 is designed for Hazardous/Classified Locations per NEC/CEC, including Class I Division 2, Class II Division 1, and Class III. It suits chemical plants, refineries, water treatment, and offshore facilities where durable, weather-resistant illumination is essential, backed by IP66 protection and a NEMA 4 enclosure for rugged environments.
The fixture operates on 120–277 VAC, 50/60 Hz, with four T8 bi-pin fluorescent lamps totaling 32 W. It measures 4 ft in length, uses an through-feed design with two NPT hubs, a bolted-door enclosure, and includes an emergency ballast for outage safety while maintaining illumination.
IP66 provides complete protection against dust and powerful water jets, while NEMA 4 enclosures resist weather, corrosion, and impact. For maintenance teams, this reduces enclosure leakage, protects internal drivers, and extends service intervals in washdown-ready, outdoor, or chemical-processing areas.
Yes. The fixture includes an emergency battery back-up ballast that powers one lamp during outages, supporting safe egress and compliance with emergency lighting standards. This is particularly critical in facilities where uninterrupted illumination is a safety and regulatory priority.
Through-feed wiring, bolted-door access, and a 4-ft, 4-lamp form factor streamline installation and service. The 32W fluorescent configuration reduces energy costs, while IP66/NEMA 4 protection and NEC/CEC compliance lower maintenance and regulatory risk, delivering a favorable total cost of ownership and enhanced uptime.
