Overview

The Hammond Power TN2A0075KBKF is a 75kVA, three-phase transformer designed for reliable power conversion. It features copper windings for efficient energy transfer and converts 480 Volts AC primary to 208Y/120 Volts AC secondary. This transformer operates at a 60 Hertz system frequency. Constructed with three coils and a single 3-leg core, it meets or exceeds NEMA standards for primary side taps. The transformer is housed within a NEMA Type 4 enclosure, providing protection against dust and water ingress, suitable for various industrial settings. Transformers of 15kVA and larger are ventilated and convection air-cooled. This unit is designed, constructed, and rated in accordance with UL, CSA, and NEMA standards. For non-linear load applications, de-rating per ANSI/IEEE C57.110 may be required. The TN2A0075KBKF is a robust component for power distribution systems requiring dependable voltage transformation and environmental protection.
  • The transformer core and coil is completely encapsulated in epoxy and silica, providing excellent protection from airborne contaminants and prevents the ingress of moisture.
  • The three phase design has a removable hinged door and factory installed grounding lugs, reducing installation time and money.
  • Copper windings for efficient power transfer
  • NEMA Type 4 enclosure for environmental protection
  • Encapsulated design for reduced moisture and particulate contamination
  • Manufactured in the US by Hammond Power Solutions
