Eaton Specification Sheet - SPP43570L
Hazardous and Classified Locations rating with Class I, Division 2; Class II, Division 2; Class III ensures compliance in volatile environments, while IP66 and NEMA 4 provide robust protection against dust and water ingress. This combination reduces regulatory risk and maintenance costs in chemical plants, refineries, and wastewater plants. The rugged fiberglass-reinforced polyester housing delivers chemical resistance and extended service life, even in aggressive environments. Lamps are included, enabling immediate deployment and eliminating separate procurement steps, which shortens project timelines and lowers total cost of ownership. Through-feed wiring with two hubs simplifies retrofit integrations into existing 120–277 VAC systems, reducing field labor and installation complexity. The 4 ft, 3-lamp configuration delivers high lumen output with efficient 54W consumption, optimizing energy use in long-run corridors and work areas. T5HO mini bi-pin lamps support common maintenance stock, while matte polycarbonate lens provides impact resistance and clear visibility in harsh conditions. This fixture aligns with NEC/CEC standards, delivering reliable performance in hazardous facilities while maintaining compatibility with Pauluhn Intrepid lighting families and retrofit strategies.
