Overview

The Hammond Power Solutions (HPS) TN2A0009KBKF is a three-phase encapsulated transformer designed for industrial power distribution in harsh environments. This 9kVA unit features copper windings for superior conductivity and thermal performance, with a primary input of 480V stepping down to a 400Y/231V secondary output. The transformer operates at 60Hz and supports a 180°C temperature rise, enabling reliable operation under substantial loads. Its Type 4 enclosure provides protection against dust, water, and corrosion, making it suitable for hazardous or outdoor applications. The encapsulated design safeguards internal components from moisture and contaminants, reducing maintenance requirements and extending operational life. Constructed with a three-coil, single 3-leg core configuration, this transformer meets NEMA standards for taps and is designed for convection air cooling. Primary voltage options include 208V, 240V, 480V, 600V, and others, while secondary voltages range from 208Y/120V to 600Y/347V. Ideal for industrial facilities requiring stable power conversion in challenging conditions.
  • 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.
  • HPS Series of harsh environment transformers is available in two lines: cULus Listed – approved for applications requiring UL and/or CSA certifications; IECEx, ATEX, UKEx Certified – approved for applications requiring IEC conformity
  • 180°C temperature rise, 60Hz operation, convection air cooled
