FAQs
For installation, ensure the 480 V primary and 120/240 V secondary ratings match your panel supply and load. Mount the unit within its NEMA 4X, Grade 304 stainless steel enclosure to resist corrosion in indoor-outdoor environments. Plan for proper ventilation, secure mounting, and compatible conduit entries. Verify the enclosure size and wiring clearance align with panel design and code requirements.
Key specs include a 15 kVA VA rating, 480 V primary, and 120/240 V secondary, 60 Hz single-phase operation, and a temperature rise of 80 °C. It features taps at 2 at +2.5% FCAN and 4 at -2.5% FCBN to accommodate voltage variation. The aluminum coil supports efficient heat dissipation and lightweight handling.
Yes. The transformer is designed for indoor-outdoor use with a NEMA 4X enclosure and 304 stainless steel construction, providing corrosion resistance in wash-down or harsh environments. When installing outdoors, ensure proper weather exposure handling, secure mounting, and confirmed drainage where applicable. Always follow manufacturer guidance for ambient temperature and enclosure installation.
Certification details are provided by Eaton and may vary by lot and region. The datasheet references manufacturer-listed approvals, including UL/CSA listings and CE compliance options for global deployments. Confirm the exact certifications with Eaton and verify them against your facility’s regulatory requirements before commissioning the installation.
The rugged encapsulated design and corrosion-resistant enclosure reduce downtime and maintenance costs in challenging environments. A single 15 kVA transformer can streamline panel architecture, lowering inventory and installation labor. Long-term savings arise from fewer spare parts, fewer fault incidents due to voltage instability, and improved uptime for critical machinery and control systems.
