Eaton HPAB42574HR Pauluhn Summit HPA - IP66 Hazardous
Part Number: HPAB42574HR
Quick Summary
Eaton HPAB42574HR linear fluorescent fixture provides reliable hazardous-location illumination for industrial facilities. Too many options fail in demanding environments or require constant maintenance and costly downtime. This model meets Hazardous/Classified Locations with IP66 and NEMA 4 protection, plus NEC/CEC compliance. With a 54 W, two-lamp configuration and through-feed installation, it reduces energy use and wiring time for hazardous-area lighting. Operators benefit from acrylic lens durability and a high-reflectance reflector that boosts lumen maintenance and visibility. Designed for 50/60 Hz operation across a wide voltage range and with sturdy aluminum housing, it stands up to harsh environments while simplifying procurement and maintenance planning.

Through-feed wiring with a 3/4 inch entry and two NPT hubs enables straightforward field connections. Impact: This design reduces conduit runs, minimizes termination errors, and speeds electrical commissioning in hazardous locations. Application: Ideal for long runs and multi-zone layouts in chemical processing, oil and gas, and other demanding facilities. 54W dual-lamp configuration in a 4 ft length using T5HO mini bi-pin lamps delivers balanced brightness. Impact: The efficient two-lamp setup lowers energy use while maintaining required lumen levels for critical work areas. Application: Suitable for production lines, cleanroom-adjacent spaces, and process areas where reliable, code-compliant lighting is essential. IP66 ingress protection, NEMA 4 enclosure, and NEC/CEC compliance to hazardous locations (Class I, Division 2; Class II/III as listed). Impact: Provides robust resistance to dust, water jets, and chemical exposure, boosting uptime and safety. Application: Hazardous locations across oil, gas, chemical processing, and manufacturing facilities. Aluminum housing paired with an acrylic lens combines durability with clear optical transmission. Impact: The rugged construction resists corrosion and impacts, while the lens maintains visibility in dusty or humid spaces. Application: Outdoor-rated or harsh indoor environments where long service life and minimal maintenance are valued. High reflectance reflector optimizes light distribution, improving usable light per watt. Impact: Higher efficiency reduces the number of fixtures needed to achieve target illuminance, cutting installed costs. Application: Warehouses, manufacturing floors, and assembly lines seeking cost-effective, high-visibility operation. Wide voltage range of 120-277 VAC and 50/60 Hz compatibility offers flexible power delivery. Impact: This versatility supports multi-site deployments and simplifies procurement by reducing ballast and ballast-related concerns. Application: Global facilities and multi-region operations requiring consistent hazardous-location lighting across sites. Through-feed configuration with bolted-door access enables clean sealing and safer maintenance. Impact: Quick access and secure enclosure support safer servicing and reduced downtime during routine maintenance. Application: Retrofits and new builds in Class I/Division 2 or Class II environments where continuity matters.
