Eaton Specification Sheet - N48M28T45CULS42
Feature → Business Impact → Application: K-Factor nonlinear design improves loading tolerance and reliability under non-linear harmonics, reducing voltage fluctuations and protecting sensitive equipment; applied in data centers and processing lines where power quality matters. Feature → Business Impact → Application: Ventilated cooling with a 150°C rise rating enables extended continuous operation in hot environments, lowering the risk of thermal derating and downtime for manufacturing lines. Feature → Business Impact → Application: Copper windings provide high electrical efficiency and durability, delivering lower I²R losses and longer life for high-current drives and motors. Feature → Business Impact → Application: Electrostatic shielding reduces EMI, improving performance of nearby control systems and sensors in factory floors and outdoor installations. Feature → Business Impact → Application: Tap settings—2 at +2.5% and 4 at -2.5%—allow precise voltage regulation to accommodate supply variations on diverse sites. Feature → Business Impact → Application: Weathershield WS39 option and low sound level (42 dB) support outdoor installations and noise-sensitive environments, enhancing installation flexibility and compliance. Feature → Business Impact → Application: UL Listed certification and a 1-year warranty from installation (or 18 months from shipment) provide procurement confidence, regulatory compliance, and predictable total cost of ownership for industrial power conditioning projects.

FAQs
This is a three-phase transformer with a 915D frame, dimensions around 22 in L, 29 in W, 39 in H, weight ~572 lb. It uses copper windings, 60 Hz operation, and accepts a primary of 480 V with a secondary of 208Y/120 V. Ensure adequate mounting clearance, proper enclosure, and alignment with your panel topology for straightforward bolting and connection.
The unit is rated at 45 kVA with 60 Hz operation, 480 V primary and 208Y/120 V secondary. It features a K-Factor nonlinear design (K-13), copper windings, and a 150°C rise. Tap settings include 2 taps at +2.5% and 4 taps at -2.5% to compensate voltage variations on site.
Yes. The product supports Weathershield options (WS39) and is designed for robust outdoor or exposed installations. It also has a low sound rating of 42 dB, aiding compliance with noise limits in plant yards or near sensitive equipment.
The transformer is UL Listed, providing verified electrical-safety compliance. The shielded design and copper windings also support EMI considerations, and the unit is compatible with Eaton’s power management ecosystem for ongoing support and maintenance.
Eaton provides a one-year warranty from installation or 18 months from shipment, whichever occurs first. With copper windings, robust cooling, and a long 45 kVA service life, operators can expect reduced maintenance costs and improved uptime, contributing to a favorable total cost of ownership over the equipment lifecycle.
