FAQs

To ensure safe operation, verify the fixture is rated for the specific hazardous location (Class I, Zone 2; Division 2; Class II, Division 1; Class III). Use the 3/4 inch entry provisions for cabling, mount flush to the ceiling, and follow the installation instructions (IF 1932 family) to preserve IP66/IP67 integrity and maintain NEMA 4X protection. Confirm voltage (347–480 VAC) and 50/60 Hz compatibility with your panel schedule.
The MLLA4-UNV34-S903D-M2 operates on 347–480 VAC at 50/60 Hz and offers a high power factor greater than 0.98. With an input of 59 W and 8000 lumens, it delivers efficient, stable illumination across industrial electrical distributions while minimizing reactive power and wiring losses in large facilities.
Yes. This luminaire is designed for Hazardous/Classified Locations and carries NEC/CEC compliance, with Class I, Zone 2 (and other related classifications) ratings, along with UL/Canada certifications. Its IP66/IP67 protection and NEMA 4X enclosure provide robust performance in aggressive, dusty, or damp chemical processing areas.
With an LED life projection and a 4 ft, diffused lens design, the fixture minimizes lumen depreciation and reduces replacement cycles. The rugged copper-free aluminum housing resists corrosion, lowering maintenance costs in harsh environments. The high efficiency (135 lm/W) also reduces energy bills, contributing to a favorable total cost of ownership in hazardous-location facilities.
The MLLA4-UNV34-S903D-M2 carries Hazardous/Classified Location ratings, IP66/IP67, NEMA 4X, and NEC/CEC compliance. Supporting documentation includes UL certification reports, installation sheets, and the Eaton specification sheet, accessible via the provided assets in the product data set for quick regulatory verification.
