EPZ encapsulation provides a rugged, sealed winding enclosure that minimizes moisture ingress and ignition risk. This translates to higher up-time and safety in Class I Division 2 environments. Apply it in chemical plants, refineries, or outdoor control stations where hazardous area compliance and reliable power are critical. Aluminum coil construction reduces overall weight and improves heat dissipation in compact installations. Lighter weight eases on-site handling, reducing crane time and labor costs during installation. The corrosion resistance of aluminum supports longer service life in outdoor or damp environments common to process facilities. Rated at 5 kVA with 480 V primary and 120 V secondary, this transformer covers standard plant control circuits and instrumentation. The 50/60 Hz single-phase design aligns with most factory power systems, enabling seamless integration with existing panels. A 115 °C rise provides a robust margin for continuous operation in warm environments. Designed for indoor-outdoor use with a NEMA 3R enclosure, this unit withstands weather and daily washdowns. Catalog notes acknowledge Grade 316 stainless steel enclosure options without implying a 4X rating, offering a path to enhanced corrosion resistance where required while maintaining regulatory compliance. CSA Certified and UL Listed, the transformer meets essential electrical-safety standards for industrial applications. The EPZ design complements these certifications by delivering consistent performance under fluctuating loads. Eaton’s warranty policy provides protection from installation through year one, supporting maintenance planning and total cost of ownership. Compatibility with standard 511C wiring, non-tapped primary, and a compact 177H frame simplify mounting in existing enclosures. The 9.89 in length, 15.54 in width, and 16.53 in height help with layout planning and spare-space budgeting in panel assemblies.
