FAQs
The 746AQ supports surface mounting in Class I Division 2 / Zone 2 locations with NEC/CEC compliance. It operates at 120 VAC using a 500W quartz halogen lamp, and its copper-free aluminum housing plus heat resistant glass lens resist harsh chemicals and heat. Ensure IP66 protection and a NEMA 4X enclosure are maintained, and follow Eaton installation sheets for wiring and mounting clearances.
IP66 provides complete dust protection and resistance to powerful water jets, while NEMA 4X adds corrosion resistance for outdoor or coastal environments. The 746AQ achieves these through a copper-free aluminum housing, a heat-resistant glass lens, sealed gaskets, and robust mounting hardware. This combination supports reliable operation in chemical plants, refineries, and offshore facilities.
The 746AQ uses a quartz halogen lamp rated at 500W and operates at 120 VAC. This configuration offers high luminous flux and fast warm-up, ideal for demanding hazardous-area lighting. Replacement lamps are available through Eaton's catalog, and the unit’s wiring remains compatible with standard 120V electrical systems, simplifying retrofits.
Industries such as chemical processing, oil and gas, refining, and mining benefit from the 746AQ’s combination of high-intensity lighting and rugged enclosure. Its Class I Division 2 / Zone 2 readiness, IP66/NEMA 4X protection, and surface-mount versatility support uptime, safer operations, and regulatory compliance in harsh environments.
The copper-free aluminum construction resists corrosion, extending service life in aggressive environments. The 500W quartz lamp delivers lasting brightness, and the heat-resistant lens reduces replacement frequency. Coupled with IP66/NEMA 4X protection and easy surface mounting, facilities experience lower downtime, fewer part replacements, and a faster return on investment.
