Eaton N48M28T15CUNV Transformer - K-13, UL Listed
Part Number: N48M28T15CUNV
Quick Summary
Eaton N48M28T15CUNV transformer provides reliable three-phase power isolation and regulation for industrial control panels. Design challenges like limited enclosure space and maintenance downtime are common in modern plants. UL Listed safety certification, a K-13 non-linear design, and a 150°C rise rating support safe, reliable operation. With primary 480 V and secondary 208Y/120 V, it integrates into industrial power distribution while minimizing footprint. This transformer also reduces maintenance costs and downtime through a totally enclosed, non-ventilated design that resists dust and contaminants. The combination of copper windings, an electrostatic shield, and a rugged 912BN frame supports long service life in demanding environments.

Special features
Electrostatically Shielded
Feature → Business Impact → Application: Totally enclosed non-ventilated construction eliminates external cooling fans and reduces dust ingress, lowering maintenance and increasing mean time between failures (MTBF) in harsh facilities. Application: control panels in dirty or confined spaces where ventilation is impractical. Feature → K-13 non-linear design → improves performance under non-linear loads from drives or rectifiers, reducing voltage distortion and enhancing system reliability. Application: motor control centers and power-distribution panels facing harmonics. Feature → 15 kVA, 480 V primary, 208Y/120 V secondary → enables compact, scalable power for mid-size control architectures; 60 Hz operation supports standard U.S. industrial grids. Application: panel boards, machine centers, and process lines. Feature → Copper windings and electrostatic shield → deliver lower losses and EMI suppression, improving signal integrity in sensitive equipment. Application: PLCs, drives, sensors near transformers. Feature → Taps at +2.5% FCAN and -2.5% FCBN → facilitate precise voltage tuning during commissioning and load changes. Application: field service and retrofit projects. Feature → Frame 912BN and weight 415 lb → robust mounting compatibility with standard transformer pads or enclosures; predictable handling during installation. Application: retrofit in existing footprints and new builds in manufacturing facilities.

FAQs
Plan for a non-ventilated, totally enclosed transformer installation with front-access for service. The unit measures 16.5 in deep, 30 in high, and 23 in wide and weighs 415 lb, mounted on a 912BN frame. Ensure enclosure clearance, proper electrical isolation, and secure mounting to support safe cooling, wiring access, and compliant maintenance.
The transformer delivers 15 kVA at 60 Hz with a 480 V primary and 208Y/120 V secondary. It uses copper windings and includes taps at +2.5% FCAN and -2.5% FCBN to fine-tune voltage during commissioning. Designed for three-phase power distribution in industrial control panels with reliable voltage regulation.
Yes. The K-13 design supports non-linear load conditions common with drives and rectifiers, reducing voltage distortion and improving overall system performance. The electrostatic shield and copper windings further help minimize EMI and maintain signal integrity in control electronics and sensor networks.
This transformer is UL Listed, ensuring compliance with recognized electrical safety standards for installation in commercial and industrial environments. While CE or IP ratings are not specified in the data, UL Listing provides a rigorous safety baseline for integration with traditional industrial controls and power distribution outfits.
The product carries Eaton’s warranty of one year from installation or eighteen months from shipment, whichever occurs first. Maintenance benefits include a corrosion-resistant, non-ventilated enclosure that lowers fan and filtration needs, copper windings for durability, and a robust 912BN frame that supports long service life with minimal routine servicing.
