Eaton HPAB46573 Linear Fluorescent Light Fixture - IP66
Part Number: HPAB46573
Quick Summary
HPAB46573 linear fluorescent light fixture provides rugged illumination for hazardous locations in industrial facilities. Maintenance downtime and re-lamping in hazardous environments can drive costs and risk, but this luminaire is built for reliability. It complies with NEC/CEC standards and hazardous location ratings (Class I, Division 2; Class II, Division 1/2; Class III), plus IP66 and NEMA 4 for rugged environments. Designed for pendant mounting with 6 lamps over 4 ft of illumination, it supports 120–277 VAC at 50/60 Hz and minimizes energy costs while maximizing uptime. This 54W fixture aligns with modern efficiency targets, and the acrylic lens provides clear visibility in demanding environments. This makes it a reliable choice for plant-wide retrofits and new builds requiring hazardous-area compliant lighting.
