FAQs
The transformer requires approximately 24 in depth, 30.5 in width, and 43 in height of clearance, with an estimated weight of 680 lb. Plan for proper lifting equipment and ensure ventilation around the unit. Use compatible enclosures and mounting hardware, and align with the Eaton Flex Center ecosystem when integrating into existing power layouts.
The K-Factor nonlinear vented design targets harmonic loading and non-linear demands, improving heat dissipation and reducing winding temperature rise. This yields more stable voltage under varying loads, extends insulation life, and supports reliable operation in automation panels and process lines with intermittent duty cycles.
Yes. The 480Y/120 secondary with a 30 kVA three-phase rating is well-suited for distributing power to automation cabinets and plant equipment. Ensure panel boards and switchgear are rated for this transformer, verify adequate ventilation, and coordinate with electrical design to balance phases and prevent localized overloads.
UL Listed confirms compliance with established safety standards for electrical equipment, reducing safety risk and easing procurement. CE conformity and IP ratings depend on regional requirements and installation conditions; verify local codes and select enclosures with appropriate IP ratings for dusty or wet environments to ensure full compliance.
Maintenance focuses on ensuring vent pathways remain unobstructed and that cooling performance is intact. Expect periodic inspections and attention to insulation condition where applicable. The robust 680 lb design and reliable cooling reduce unplanned downtime, delivering ROI through improved uptime, predictable performance, and lower energy losses in harmonic-rich applications.
