Eaton Specification Sheet - 746A
The IP66 and NEMA 4X ratings translate to superior protection against dust, water ingress, and corrosion, significantly reducing unplanned downtime in chemical plants, refineries, and mining sites. This translates to safer operations and lower maintenance costs as inspectors trust a fixture that resists harsh environments and passenger-grade wear. The copper-free aluminum housing delivers excellent corrosion resistance while keeping weight manageable for field installs, enabling quicker commissioning and fewer mounting compromises in tight spaces. A heat-resistant glass lens shields the incandescent lamp from thermal stress, increasing lamp life in high-temperature zones and reducing replacement cycles. Surface mounting simplifies installation workflows, cutting labor costs and enabling retrofits in crowded instrument rooms or outdoor platforms. The 300W lamp with medium optical distribution provides reliable, uniform coverage for task-critical areas, improving operator safety and productivity. Designed for 120 VAC circuits, it integrates with standard plant electrical systems without requiring special power infrastructure, supporting efficient procurement and spare-part planning. In addition, documented installation and configuration sheets reduce on-site errors and accelerate commissioning, delivering predictable performance from day one.

FAQs
The 746A is specified for surface mounting, which simplifies installation in control rooms, walkways, and outdoor platforms within hazardous locations. Its copper-free aluminum housing and heat-resistant glass lens are designed to withstand challenging industrial conditions, reducing field adjustments and maintenance time. When planning installations, consider available installation sheets (LBL1520) to ensure proper mounting clearances and wiring access, and verify that surface mounting is compatible with your enclosure configurations and space constraints.
The 746A achieves IP66 protection against dust ingress and powerful water jets, while the NEMA 4X rating indicates corrosion resistance and suitability for outdoor and washdown environments. This combination supports operation in chemical plants, offshore platforms, and other facilities with exposure to moisture, dust, and corrosive atmospheres. NEC/CEC compliance and Class I, Division 2 Zone 2 ratings further confirm suitability for hazardous locations, reducing compliance risk and inspection hassles during installation and maintenance.
Yes. The 746A is rated for Class I, Division 2 and Zone 2 locations, aligning with NEC/CEC standards and hazardous-area classifications. It carries a NEMA 4X enclosure and IP66 protection, providing robust environmental sealing. This combination supports compliance with hazardous-location requirements in chemical processing, refining, and other critical industrial settings, helping facilities meet regulatory expectations while delivering reliable illumination.
Maintenance considerations center on lamp replacement (incandescent 300W) and periodic lens cleaning while ensuring seals remain intact to preserve IP66/NEMA 4X integrity. The availability of installation sheets and specification sheets from Eaton supports service planning and part lookup. Operators should maintain an inventory of replacement lamps and gasket seals, and schedule inspections aligned with hazardous-location maintenance programs to sustain performance and safety.
Total cost of ownership combines initial procurement, installation labor, and ongoing maintenance. The 746A’s rugged copper-free aluminum housing, long service life from heat-resistant glass, and high ingress protection reduce downtime and replacement cycles, delivering lower maintenance costs over time. Its surface-mount design streamlines installation, minimizing commissioning time and labor. For ROI, compare the fixture’s uptime gains against lamp replacement costs and maintenance labor over a multi-year horizon, and factor in regulatory compliance savings from using a certified hazardous-location luminaire.
