Overview

The Hammond Power TE3A0020KKM is a 20 kVA, three-phase drive isolation transformer designed to meet stringent energy efficiency standards, including DOE 2016 and NRCan 2019. This transformer operates with a primary voltage of 480D and a secondary voltage of 480Y/277 V, making it suitable for a variety of industrial applications. Constructed with copper (CU) windings, it ensures reliable performance and efficient power transfer. The enclosure is rated NEMA 3R, providing protection against falling rain and sleet, suitable for outdoor or exposed installations. Operating at a frequency of 60 Hz, this transformer is built for standard North American power grids. Its robust design and adherence to energy efficiency regulations contribute to reduced operational costs and environmental impact. The TE3A series from Hammond Power is engineered for demanding drive isolation applications where clean power and reliable operation are paramount. This unit is manufactured in the USA, ensuring quality and compliance with domestic manufacturing standards. The SKU TE3A0020KKM signifies a specific configuration within the TE3A series, optimized for drive isolation with a 20 kVA capacity and a 480D primary to 480Y/277V secondary voltage configuration. Its 3-pole design is standard for three-phase power distribution. The 3R enclosure type offers a balance of protection and ventilation for various industrial environments. This transformer is an essential component for ensuring the longevity and optimal performance of variable frequency drives (VFDs) and other sensitive motor control equipment by isolating them from line notching and voltage transients. Its energy-efficient design translates directly into lower energy consumption and reduced electricity bills over the lifespan of the equipment. The use of copper windings maximizes conductivity and minimizes resistive losses, further enhancing efficiency. This unit is a direct replacement for older, less efficient transformers, offering a significant upgrade in performance and compliance.
