Hazardous-location encapsulated design reduces ignition risk and helps maintain regulatory compliance in Class 1 Division 2 environments, enabling safer operation in chemical plants, refineries, and mining sites. The Grade 304 stainless steel enclosure supports corrosion resistance and durability in demanding spaces, while the NEMA 3R rating provides reliable indoor-outdoor performance, reducing enclosure damage and maintenance. Three-phase operation with 480 V primary and 208Y/120 V secondary ensures compatibility with common industrial power systems and control circuits, improving install efficiency and minimizing field modifications. Two taps at -5% FCBN on the primary winding offer voltage flexibility to accommodate minor supply fluctuations, supporting stable load performance and reduced equipment stress. Aluminum windings provide good thermal performance and cost efficiency, contributing to lower life-cycle costs and easier maintenance planning. The unit’s 70 A wiring connection and 15 kVA rating align with typical distribution schemes, helping engineers design compact, compliant layouts.UL Listed certification and Eaton warranty reinforce long-term reliability and support.

FAQs
Install in accordance with Class 1 Division 2 requirements and local codes. The unit features a Grade 304 stainless steel enclosure with a NEMA 3R rating, suitable for indoor-outdoor use. Ensure proper clearance, secure mounting, correct cable glands, and verify the 70A wiring connections. Set the -5% taps as required to match supply voltage and minimize voltage drop.
The transformer is three-phase, 15 kVA with a 480 V primary and 208Y/120 V secondary, compatible with 50/60 Hz systems. Aluminum windings provide good thermal performance. With 2 taps at -5% FCBN and a 70A wiring connection, plan for loads not exceeding 15 kVA to maintain voltage regulation and avoid overheating during peak demand.
Yes. It is designed for Class 1 Division 2 hazardous locations (Groups C and D) and is UL Listed. The enclosure is Grade 304 stainless steel with a NEMA 3R rating for indoor-outdoor use, offering robust protection in challenging environments and helping meet safety and compliance targets for regulated facilities.
Absolutely. The enclosure is Grade 304 stainless steel and rated NEMA 3R, enabling reliable service in both indoor and outdoor settings. The corrosion-resistant construction and weather-resilient design reduce maintenance cycles, making it suitable for harsh environments like chemical plants, oil & gas sites, and outdoor control rooms.
The UL listing and Class 1 Division 2 rating reduce compliance risk and potential downtime, delivering a strong return on safety investments. The encapsulated design minimizes insulation degradation and maintenance needs, while the stainless enclosure withstands harsh conditions. Plan for periodic visual inspections, verify tap settings, and monitor for thermal performance; warranty is one year from installation (or 18 months from shipment).
