FAQs
Plan for a ventilated enclosure and ensure sufficient clearance for the 4-in window and copper windings. Verify mounting footprint compatibility with the EE frame and provide accessible taps for any future voltage adjustments. Confirm source voltage availability matches 480 V primary and 208Y/120 V secondary requirements, and factor in service clearance for routine maintenance.
The transformer uses a K-Factor nonlinear design with copper windings and an 80°C rise rating to manage heat and nonlinear loading. Taps at ±2.5% allow fine voltage regulation, while the ventilated cooling path helps dissipate heat during peak conditions, reducing voltage sag and insulation stress in connected equipment.
Yes. With a 75 kVA rating and three-phase KT-13 configuration, it is well-suited for data centers and manufacturing environments requiring reliable power conditioning, tight voltage regulation, and efficient heat management in compact spaces. Ensure panel boards and switchgear are compatible with its 480 V primary and 208Y/120 V secondary outputs.
The product specifies certifications as ‘Contact Manufacturer,’ so you should request current certification documentation from Eaton or the distributor. Typical expectations for industrial transformers include CE, UL/CSA, and IP ratings depending on the installation, but always confirm with the supplier to ensure the unit meets your regulatory and environmental requirements.
Expect improved reliability and reduced maintenance due to copper windings, efficient heat management, and precise voltage taps that minimize wear on downstream equipment. The 75 kVA rating supports scalable power distribution, while the ventilated design reduces cooling energy needs in active facilities, contributing to lower total cost of ownership over time.
