FAQs
Plan for a three-phase installation with a 916AN frame and footprint of 23.42 in by 28.22 in by 46.58 in. The unit weighs 926 lb, so use appropriate lifting and mounting hardware. Verify ambient conditions meet dry-type transformer requirements and ensure adequate clearance for maintenance access around the enclosure.
Confirm 75 kVA rating, 60 Hz operation, primary voltage of 480 V, secondary voltage of 208Y/120 V, aluminum windings, and DT-3 design. Check temperature rise rating of 150 °C and the available taps: 2 at +2.5% FCAN and 4 at -2.5% FCBN to match site voltage conditions.
Yes. The totally enclosed non-ventilated design protects windings and internal components from dust and particulates, reducing maintenance needs and extending service life in challenging environments like manufacturing floors and loading docks.
The transformer provides 2 taps at +2.5% FCAN and 4 taps at -2.5% FCBN to accommodate voltage variations on the supply or loads. Use taps during commissioning to optimize voltage at the secondary bus and to prevent overvoltage or undervoltage conditions on connected equipment.
The unit is covered by Eaton Selling Policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. This warranty supports parts and workmanship, with Eaton’s technical support available for installation guidance, field service coordination, and replacement parts.
