FAQs
The EHAR42572012EMT3 is designed for universal 120–277 VAC operation with 50/60 Hz. This broad voltage range enables simple integration across global facilities, reduces the need for separate drivers, and supports straightforward retrofits in existing Pauluhn ECOS installations without extensive rewiring.
This fixture uses zinc Myers conduit hubs with one entry at each end and 3/4" entry size, aiding flexible wiring routes. Wall mounting suits a variety of layouts, and the end-entry configuration simplifies wiring in constrained spaces while meeting NEC/CEC requirements for safe, code-compliant installation.
EHAR42572012EMT3 features an IP66 rating and a NEMA 4X enclosure, plus an Ordinary/Non-Hazardous area classification. This combination makes it suitable for non-hazardous environments and washdown zones, while still delivering robust protection against moisture, dust, and corrosion in harsh industrial spaces.
The unit includes an emergency battery back-up ballast for safe operation during outages, a polycarbonate lens for impact resistance, and a fiberglass-reinforced polyester housing for chemical and environmental durability. With a 54W, 2-lamp design, service intervals are extended and replacement parts are readily available through Eaton's Pauluhn ECOS line.
At 54W for a 4 ft, 2-lamp luminaire, the EHAR42572012EMT3 delivers meaningful energy savings over traditional ballast configurations. When paired with emergency back-up and durable construction, facilities benefit from lower maintenance costs, reduced downtime, and improved safety compliance, contributing to a favorable total cost of ownership in high-use industrial spaces.
