The Z48G22T09A uses a Class 1 Division 2, Groups C and D hazardous location design with aluminum windings and an EPTZ configuration to provide reliable power transformation in environments with ignition risks, reducing the likelihood of arcing or insulation failures. This translates to improved equipment uptime and lower maintenance costs, enabling safer operation of critical loads in petrochemical, refining, and other high-risk facilities. With a 9 kVA rating and a 480 V primary to 240/120 V secondary, it supports common industrial distribution schemes while offering two taps at -5% FCBN to fine-tune voltage and minimize downstream equipment stress. The NEMA 3R enclosure ensures indoor-outdoor compatibility, simplifying installation in areas with variable weather conditions and limited cabinet space. The use of aluminum windings enhances thermal performance and corrosion resistance, helping sustain efficiency over long service lives. Deployment is streamlined by a 62AA wiring connection and a compact 243H frame, which support straightforward mounting and panel integration. The transformer’s 60 Hz frequency and three-phase configuration provide compatibility with typical plant power systems, while the 150°C rise rating indicates robust thermal management for hot environments. In practice, this means safer startups, more predictable voltage performance, and a lower total cost of ownership for hazardous-area power distribution projects.

FAQs
The unit is a three-phase, 9 kVA transformer with 480 V primary and 240/120 V secondary, wired via 62AA connections. It features a NEMA 3R indoor-outdoor enclosure and a frame size of 243H, enabling straightforward wall or rack mounting and simple integration with existing distribution panels. Use the -5% FCBN taps to fine-tune voltage during commissioning and ensure proper clearance per local codes.
A 9 kVA rating supports moderate downstream loads with ample headroom, while a 150 °C rise indicates robust thermal design. This combination allows safe operation under elevated ambient temperatures common in industrial plants, reducing the risk of over-temperature trips and enabling stable voltage delivery to 240/120 V loads across hot environments.
Yes. The Z48G22T09A is designed for Class I Division 2, Groups C and D hazardous locations, offering encapsulation and protective features to minimize ignition risks. Its UL Listed certification and NEMA 3R indoor-outdoor rating make it suitable for challenging environments like petrochemical plants and mobile offshore facilities where reliable power distribution is essential.
The model is UL Listed, confirming adherence to recognized safety standards for electrical equipment. In addition, its Class I Division 2 hazardous location designation and NEMA 3R enclosure support compliance with major electrical codes and industry guidelines, easing approval processes for installations in restricted areas while ensuring safe operation of high-risk loads.
The transformer carries Eaton’s warranty policy: one year from installation or eighteen months from shipment, whichever occurs first. This, combined with rugged aluminum windings, encapsulation, and durable enclosure, reduces maintenance intervals and mitigates unplanned downtime. The result is lower lifecycle costs and improved return on investment for facilities requiring dependable hazardous-location power distribution.
