FAQs
HPSB42570 supports pendant mounting with 1/2" entry and (2) NPT hubs, operating on 120-277 VAC at 50/60 Hz. It is designed for Class I, Division 2 and other hazardous classifications per NEC/CEC, with a bolted door and 304 stainless steel body. For best results, follow Eaton installation sheets and ensure power is shut off during a site retrofit.
IP66 protection means complete protection against dust ingress and powerful water jets, which, combined with a sealed bolted door and NEMA 4X enclosure, keeps electronics and optics safe from moisture and contaminants. This translates to lower maintenance, longer lamp life, and reliable operation in washdown areas common to chemical plants and offshore facilities.
Yes. The fixture is rated for Hazardous/Classified Locations with NEC/CEC compliance, supporting Class I, Division 2 and related classifications. The combination of IP66 and NEMA 4X enclosure provides robust protection in corrosive environments, enabling compliant operation without sacrificing lighting performance in challenging industrial sites.
Maintenance is streamlined by the 304 stainless steel body, acrylic lens, and bolted door design, which simplify cleaning and lamp replacement. With a 54W two-lamp configuration and readily available T5HO mini bi-pin lamps, routine tasks are reduced and downtime shortened. Regular inspection should focus on lens clarity, door seals, and wiring terminations in harsh environments.
The fixture delivers durable, corrosion-resistant construction, IP66/NEMA 4X protection, and energy-efficient 54W operation, which lowers replacement costs and downtime. While initial costs may be higher than non-hazardous-area fixtures, long-term savings accrue from fewer maintenance events, reduced risk in regulatory audits, and extended service life in demanding industrial settings.
