FAQs
Plan for a footprint around 24.88 in wide by 21.13 in deep with a height of 36.88 in. The unit weighs approximately 430 lb, so use appropriate mounting hardware and mechanical supports. Ensure adequate clearance for ventilation and access to connections. Use standard three-phase switchgear compatibility and follow the Eaton installation guide for safe, code-compliant mounting.
Yes. The transformer is rated for 480-208Y/120 V in a three-phase configuration and provides up to 30 kVA of power. It supports typical factory and data-center loads that fall within this rating, enabling safe step-down to common 120 V secondary circuits. Verify actual load profiles and ambient conditions against the Eaton specification sheet during planning.
The K-Factor nonlinear design prioritizes efficient heat dissipation through vented construction, reducing thermal stress on windings and insulation during peak loads. This improves reliability, extends service life, and lowers maintenance costs. For industries with fluctuating loads like manufacturing lines, this translates to lower risk of overheating and fewer unplanned outages.
The model is UL Listed, confirming adherence to recognized safety standards for industrial transformers. This certification simplifies procurement, audit readiness, and regulatory compliance for facilities seeking certified equipment. While CE or IP ratings are common, this data confirms UL safety alignment and suitability for a wide range of industrial environments.
With a 30 kVA rating and vented, heat-managed design, you can expect improved uptime and reduced cooling-related energy usage, contributing to a favorable total cost of ownership. Regular inspections should emphasize ventilation integrity, connection torque, and insulation condition. Access to Eaton’s specification sheet supports maintenance planning and long-term spare parts availability, enhancing lifecycle value.
