Feature → Business Impact → Application: Encapsulated EP design provides robust protection against dust, moisture, and corrosive environments, improving uptime and reducing enclosure maintenance in harsh factories and outdoor enclosures. This translates to lower lifecycle costs and easier certification audits for power distribution setups in processing lines and packaging facilities. Feature → 15 kVA, 240/480 V primary and 120/240 V secondary outputs supports scalable control-panel power without multiple secondary transformers, enabling smaller panel footprints and simplified wiring in machine centers. Feature → Aluminum windings deliver excellent thermal performance with lightweight construction, reducing installation labor and improving efficiency in space-limited control cabinets across automotive and material handling. Feature → NEMA 4X enclosure and Weathershield design ensure indoor-outdoor usability, meeting harsh environment demands in food processing, chemical plants, and outdoor substations. Feature → Wall mounting and a compact footprint (10.52 in D x 15.52 in H x 13.38 in W) simplify retrofits and new panel layouts, speeding up commissioning in industrial automation projects. Feature → UL Listed certification and 25-000 warranty policy provide procurement confidence and regulatory compliance, helping teams meet safety standards and service commitments while mitigating risk during audits. Feature → 60 Hz, single-phase operation aligns with common plant power circuits, streamlining compatibility with existing automation equipment and reducing the need for additional power conditioning.

FAQs
Plan a wall-mount installation within a ventilated, clean environment using the unit’s wall-mount capability and its compact 10.52 in D x 15.52 in H x 13.38 in W footprint. Verify clearance for heat dissipation, connect primary 240/480 V and secondary 120/240 V circuits with appropriate cabling, and fasten securely to reduce vibration. Ensure enclosure is closed to preserve UL and NEMA 4X integrity and perform a final insulation and continuity check before energizing.
The device is a single-phase, 60 Hz transformer with 15 kVA rating. Primary voltage options are 240 V or 480 V, and secondary voltage is 120/240 V. Aluminum windings provide good thermal performance, and the unit is designed for indoor-outdoor use within a NEMA 4X enclosure. It weighs approximately 213 lb and uses a 1804X frame.
Yes. The transformer features a NEMA 4X enclosure and Weathershield designation indicating indoor-outdoor suitability. It’s designed to resist moisture and dust ingress, making it appropriate for outdoor or harsh indoor environments common in outdoor sub-panels, plant exteriors, and exposed panel locations.
UL Listed certification ensures compliance with electrical safety standards, simplifying regulatory acceptance and commissioning. The enclosure’s NEMA 4X rating, along with indoor-outdoor capability, supports rugged installation environments. These factors reduce risk during audits and help ensure consistent performance across a plant’s power distribution network.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first, under policy 25-000. Field support includes documentation, datasheets, and access to Eaton’s specification resources. For ongoing reliability, plan preventive maintenance around the 60 Hz single-phase design and monitor aluminum windings for thermal performance during peak loads.
