FAQs
Installers should verify the 480 V primary and 120/240 V secondary connections meet local electrical codes. Use a suitable mounting surface compatible with the 179H frame, and ensure the enclosure is properly grounded to maintain NEMA 3R protection in outdoor or damp environments.
The encapsulated design protects windings and minimizes environmental ingress, making it suitable for hazardous locations. Its single-phase 15 kVA rating supports core power distribution needs, and the NEMA 3R enclosure adds outdoor reliability, reducing maintenance frequency.
Yes. The 480 V to 120/240 V secondary outputs align with common control circuitry, lighting, and motors in industrial settings. The 179H frame size facilitates retrofits and replacements in existing installations with similar footprints.
Certifications vary by region; Eaton provides manufacturer guidance for regulatory approvals. The unit features a NEMA 3R enclosure for outdoor use; consult Eaton for SIL, CE, or IP ratings applicable to your installation site.
Cost of ownership benefits come from reduced maintenance due to encapsulation, fewer leaks, and longer service life. ROI improves when downtime is minimized, as the robust enclosure and efficient power conversion lower replacement and repair expenses over the transformer’s life cycle.
