Feature to benefit alignment begins with a single-phase 10 kVA transformer that steps 480 V down to 120/240 V, enabling clean, stable control voltages for automation panels. This translates to reduced voltage variance in sensitive devices, boosting reliability and extending component life in conveyors and robotics applications. The copper coil design improves thermal efficiency and reduces copper loss, supporting cooler operation and longer service intervals in high-duty panels. The EP design paired with a Grade 304 stainless steel enclosure provides corrosion resistance and weather resilience, enabling outdoor-install readiness without compromising enclosure integrity. NEMA 3R rating reinforces indoor-outdoor suitability, minimizing corrosion-related downtime in harsh environments and simplifying compliance with installation standards. The 2-tap configuration (+2.5% FCAN / -2.5% FCBN) offers precise voltage regulation to accommodate varying line conditions and load profiles, reducing nuisance tripping and quality issues in industrial controls. A compact footprint (10.52 in depth, 13.38 in width) combined with a 19 in height and a 250 lb weight delivers a sturdy, mountable solution that fits standard electrical rooms while tolerating installation tolerances. The 16 A wiring connection supports straightforward connection to control circuits and device feeders, enabling faster, safer field wiring. With UL Listed and CSA Certified credentials, this transformer aligns with global safety and electrical standards, easing cross-site deployments and maintenance planning. Warranty coverage through Eaton’s policy ensures post-installation support and protection against manufacturing defects, enabling a lower total cost of ownership for mission-critical equipment and extended system uptime.

FAQs
This transformer uses a NEMA 3R indoor-outdoor enclosure with a Grade 304 stainless steel cabinet option and weighs about 250 lb. Plan for mounting clearance and access to the 16A wiring terminals. Ensure the enclosure is protected from physical damage and is rated for outdoor exposure if installed outside. Follow proper grounding and harness routing per local codes.
The unit has a 480 V primary and 120/240 V secondary, operating at 60 Hz in a single-phase configuration. It is rated at 10 kVA with an 80 °C rise, copper windings, and 2-tap voltage adjustment (+2.5% FCAN, -2.5% FCBN) to accommodate line variance and load conditions.
Yes. It features an indoor-outdoor Weathershield design and a NEMA 3R enclosure, enabling reliable operation in exposed or humid environments. The Grade 304 stainless steel enclosure further enhances corrosion resistance, making it appropriate for outdoor control panels and industrial installations in challenging climates.
The transformer is UL Listed and CSA Certified, signaling compliance with recognized safety and performance standards. This helps streamline integration into regulated facilities, reduces the burden of site-specific approvals, and supports consistent performance across multiple sites. The combination also supports ongoing maintenance and warranty alignment with typical industrial procurement requirements.
Eaton provides a warranty policy (25-000) offering one year from installation or 18 months from shipment, whichever occurs first. Regular visual inspections, resistor-free terminations, and periodic thermal checks are recommended to maintain performance. The copper windings and robust enclosure reduce common failure modes, contributing to lower maintenance costs and predictable ROI in power-distribution for automation systems.
