Sealed General Purpose Transformers (Resin Encapsulated)

Intended for power, heating, and lighting applications.

Public Law 109-58, the 2005 Energy Act, mandates that distribution transformers be energy efficient. However, resin-filled units are not included in this law; they are listed in Section (35)(B)(ii) as “a transformer that is designed to be used in a special purpose application and is unlikely to be used in general purpose application, such as ... sealed and non-ventilating transformer...”

Standard Features
  • Epoxy encapsulated
  • No openings in the enclosure, making these ideal for indoor and outdoor applications where airborne particles or contaminants could disrupt operation
  • Core-and-coil assembly embedded in an epoxy resin compound and wall mounted for maximum protection
  • UL Listed and CSA certified
Square D logo

Applications

  • Industrial markets
  • OEM Commercial
