FAQs
For panel installations, plan for a 96-frame enclosure with three-phase 380–480 V primary and 120/240 V secondary outputs. Use the S452L9C wiring designation for connections and accommodate the NEMA 3R indoor-outdoor enclosure. Ensure adequate clearance for heat dissipation at 115 °C rise and verify UL Listed compliance before commissioning.
Key specs include a 9 kVA volt-ampere rating, three-phase configuration, 50–60 Hz frequency, primary voltages of 380–480 V, and secondary voltages of 120/240 V. The unit uses aluminum coil material, features a NEMA 3R enclosure, and is designed for indoor-outdoor service with an electrostatically shielded construction.
Yes. The transformer comes with a NEMA 3R enclosure suitable for indoor-outdoor use, and its aluminum winding plus electrostatic shielding support EMI control in outdoor environments. Ensure mounting clearances and ambient conditions meet the catalog specifications and that UL listing is maintained in the field.
The unit is UL Listed, indicating recognized safety compliance for industrial use. It features a NEMA 3R enclosure suitable for outdoor exposure and is designed for 50–60 Hz, three-phase operation with 9 kVA rating, aligning with typical industrial control and distribution standards.
Routinely inspect for enclosure integrity, verify winds and connections, and monitor winding temperatures given the 115 °C rise rating. The 3R enclosure and aluminum coil reduce corrosion risk, improving service life. The one-year Eaton warranty (or 18 months from shipment) provides initial protection, supporting TCO optimization in panel builds.
