Feature → Business Impact → Application: The dry-type DT-3 design uses a totally enclosed non-ventilated enclosure with copper windings, delivering rugged protection in dusty or damp industrial spaces. This reduces unplanned maintenance and windings exposure, lowering total cost of ownership. Application: control panels, automation cabinets, and machine rooms where reliable operation is essential. Feature → Business Impact → Application: The 15 kVA three-phase rating supports moderate loads without oversized cabinets, enabling tighter footprint layouts. This improves energy efficiency and shortens install times while maintaining voltage stability for drives and sensors. Application: panel feeders and machine control centers in manufacturing lines. Feature → Business Impact → Application: Primary 480 V and secondary 208Y/120 V enable direct integration with common plant distributions, reducing wiring complexity and potential connection errors. This streamlines installation and commissioning, minimizes voltage drop across feeders. Application: utility-to-machine step-down in production lines. Feature → Business Impact → Application: Copper windings provide superior conductivity and thermal performance, lowering copper losses and improving efficiency under continuous operation. This translates to cooler operation and extended transformer life. Application: high-duty environments where reliability is critical. Feature → Business Impact → Application: Tap settings of 2 at +2.5% and 4 at -2.5% FCAN/FCBN allow precise voltage regulation amid line swings, reducing equipment stress on sensitive electronics and preventing nuisance tripping. Application: plant feeders with critical sensors and controls. Feature → Business Impact → Application: The enclosure, rated 80°C rise, and 912BN frame build support installation in compact footprints with robust front- and rear-access for service. This simplifies mounting, reduces space requirements, and enables safer maintenance. Application: OEM equipment housings and retrofit projects.

FAQs
The transformer is designed for control panels and machine rooms with a compact footprint. It uses a 912BN frame and weighs about 427 lb, so plan for mounting clearance, accessibility for maintenance, and adequate ventilation around the enclosure. Ensure inputs are wired to meet 480 V primary ratings and 208Y/120 V secondary connections.
Key specs include 15 kVA rating, three-phase configuration, primary 480 V, secondary 208Y/120 V, 60 Hz frequency, copper windings, and an 80 °C rise. Taps are available at 2 at +2.5% and 4 at -2.5% to accommodate voltage fluctuations in plant power feeds.
Yes. It features a totally enclosed non-ventilated enclosure and copper windings, offering protection against dust and moisture. Its DT-3 dry-type design is intended for indoor or semi-indoor installations, supporting reliable operation under typical factory conditions.
The unit is UL Listed, which provides safety certification for industrial electrical equipment. While other certifications aren’t listed in the data, UL listing is a primary compliance factor for procurement and audits in many facilities.
Maintenance needs are reduced by the enclosure protection and copper-winding design, which improve reliability and reduce runtime faults. The 1-year warranty (or 18 months from shipment) offers a baseline protection. Over the life of the transformer, reduced downtime and stable voltage regulation contribute to favorable ROI in continuous operations.
