Indoor-Outdoor
The 10 kVA, single-phase, 60 Hz design uses copper windings to deliver clean, efficient power with minimal copper losses. Business impact: predictable voltage transformation reduces heat and extends motor life, boosting overall equipment reliability. Application: ideal for compact control panels and localized power distribution in manufacturing lines. The enclosure is NEMA 4X with a 316 stainless steel body, protecting internal windings from moisture, dust, and corrosion. Business impact: lower maintenance, reduced downtime, longer service life in harsh environments. Application: indoor-outdoor installations, critical controls in production areas, outdoor equipment hubs. Voltage adaptability via multi-tap configuration: 1 at +5% FCAN, 2 at -5% FCBN, and 2 at +2.5% FCAN, 4 at -2.5% FCBN. Business impact: allows on-site voltage compensation without external equipment, saving wiring and dynamic load changes. Application: networks with fluctuating supply, equipment sensitive to minor voltage variations. Thermal performance and ratings: 150 °C rise, copper coil, 10 kVA rating provide solid thermal margin for continuous operation. Business impact: higher uptime and reduced risk of thermal cutouts. Application: industrial automation, process control, and packaging lines where downtime is costly. Inspection and installation support: catalog notes highlight indoor-outdoor suitability and standard mounting configurations; 1-year warranty plus policy. Business impact: simplified procurement, faster commissioning, and clearer service expectations. Application: system integrators and maintenance teams seeking a proven, ready-to-install transformer.

FAQs
Installers should allocate adequate panel space for the unit’s footprint, ensure proper clearance for cooling, and correctly terminate connections to the 240/480 V primary and 120/240 V secondary. The NEMA 4X enclosure and 316 stainless steel body support outdoor use; follow manufacturer mounting guidelines and use appropriate hardware to maintain protection ratings.
Key specifications include a 10 kVA rating, single-phase operation at 60 Hz, primary voltages of 240 V or 480 V, secondary voltage of 120/240 V, copper windings, and a temperature rise of 150 °C. The transformer also offers multiple taps (+5%, -5%, and ±2.5% variants) for on-site voltage compensation.
Yes. The enclosure is designed for indoor-outdoor service and uses corrosion-resistant construction, with a NEMA 4X rating and 316 stainless steel body. This makes it suitable for harsh environments on factory exteriors, outdoor equipment stations, and exposed control panels without compromising protection or performance.
Manufacturer certifications are listed as 'Contact Manufacturer' in the data. Nevertheless, the transformer utilizes a rugged NEMA 4X enclosure and corrosion-resistant materials, aligning with typical industry expectations for outdoor and harsh-environment use. Always confirm region-specific certifications (CE, IP, SIL) with Eaton before deployment.
ROI is driven by reduced downtime, longer service life, and lower maintenance due to copper windings and a robust enclosure. The 10 kVA rating supports scalable loads, while the 150 °C rise margin enables reliable operation in demanding lines. A standard warranty and durable finish further reduce lifecycle costs for automation and panel builds.
