Applications
Single phase dry type distribution transformers like the HPS NMF025LE are standard equipment in commercial and light industrial electrical systems. They are commonly used to supply branch panels, machinery, HVAC equipment, and lighting circuits where a locally derived 120/240V single phase source is needed from a higher-voltage distribution feed. The multi-tap primary (with taps from 216V to 504V as shown on the nameplate) allows the transformer to be adapted to a range of available primary voltages on site. The NEMA 3R enclosure makes it suitable for both indoor and outdoor installations where protection from rain and sleet is required. Dry type construction — meaning the core and coils are air-cooled rather than oil-immersed — eliminates the need for containment pans and simplifies installation and maintenance. Transformers of this type and rating are routinely installed in manufacturing facilities, commercial buildings, pump stations, and utility service applications.
This Hammond Power Solutions (HPS) NMF025LE 25KVA Single Phase Dry Type Transformer has been inspected and is in good used condition. It was pulled from a working environment where it was previously in service. The blue-gray steel enclosure shows light surface marks and minor scuffs consistent with typical industrial use, but there is no significant damage or rust. The conduit hubs are installed and intact.
