Eaton Z48G28E75CU Transformer - UL Listed Class I Div 2
Part Number: Z48G28E75CU
Quick Summary
Eaton Hazardous Location encapsulated transformer delivers 75 kVA for hazardous-area power distribution. Many installations struggle to meet Class I Division 2 safety while fitting into compact spaces. UL Listed, Class I Division 2 compliance, and a NEMA 3R enclosure ensure safe operation in indoor-outdoor environments. This transformer supports uptime and safer, compliant power delivery for industrial facilities. Designed to streamline procurement and installation, it complements 480 V to 208Y/120 V distribution with copper windings. In addition, its NEMA 3R enclosure and shielded copper windings reduce maintenance costs and downtime. This makes it a practical, scalable choice for retrofits and new builds. Engineers appreciate predictable performance under demanding ambient conditions.

Paragraph 1: The 75 kVA three-phase transformer delivers reliable 480 V to 208Y/120 V conversion for control panels and motor loads in hazardous locations. This simplifies wiring and reduces the number of transformers needed on site, delivering a cleaner, more maintainable power network for industrial facilities. Paragraph 2: Copper windings paired with shielded construction minimize copper losses and improve thermal performance, contributing to higher overall efficiency and longer service life in demanding environments such as chemical plants and refineries. Paragraph 3: The NEMA 3R enclosure provides weather-resilient protection for indoor-outdoor installations, enabling flexible placement and reducing enclosure-related failures in variable climates. Paragraph 4: Precise voltage regulation is supported by a 50/60 Hz rating and a -5% FCBN tap option, helping maintain stable downstream voltages for sensitive equipment like PLCs and robotics in harsh conditions. Paragraph 5: Compliance and certification, including UL Listed status and Class I Division 2 capability, minimize regulatory risk and simplify procurement for projects governed by strict hazardous-location standards. Paragraph 6: Installation considerations such as a substantial 1460 lb weight and dimensions suited to rugged footprints are balanced by a robust enclosure, enabling reliable retrofits and new installations with fewer compatibility concerns.

FAQs
For safe, code-compliant installation, ensure Class I Division 2 compliance and use a NEMA 3R enclosure suitable for indoor-outdoor use. Provide a solid foundation, proper vibration isolation, and secure mounting. Leave sufficient clearance for wiring access, allow for the 1460 lb unit weight, and follow local electrical codes during panel connections and grounding.
Key specs include 75 kVA, three-phase, primary voltage 480 V, secondary voltage 208Y/120 V, copper windings, shielded construction, NEMA 3R enclosure, 50/60 Hz operation, 115 °C rise, and a tap size of 2 at -5% FCBN. It is UL Listed and designed for Class I Division 2 hazardous locations.
Yes. The Z48G28E75CU is built for 480 V to 208Y/120 V distribution in hazardous-location settings, delivering stable voltage to control panels, MCCs, and downstream equipment while meeting Class I Division 2 requirements and using copper windings for reliability and efficiency.
This transformer is UL Listed and rated for Class I Division 2 hazardous locations, with a NEMA 3R enclosure for weather resistance. These certifications ensure safety, reduce regulatory risk, simplify procurement for regulated facilities, and facilitate faster project approvals in oil, gas, chemical, and mining applications.
The unit’s robust copper windings, shielded construction, and durable enclosure minimize thermal losses and maintenance downtime, improving uptime and extending service life. While initial cost is higher than nonhazardous-area transformers, the enhanced safety, reduced risk, and lower replacement frequency contribute to a favorable total cost of ownership over the equipment lifecycle.
