Eaton Specification Sheet - N48M28F2216CULS55
Feature: DOE2016 Efficient performance and 225 kVA rating deliver measurable operating savings in continuous-duty applications. This transformer operates at 60 Hz with a 480 V primary and 208Y/120 V secondary, achieving a 115 °C rise and copper windings designed for reliable, long-life operation. Business impact: reduced energy losses and lower cooling costs support predictable budgets and longer intervals between service windows. Application: ideal for heavy manufacturing, data centers, and process facilities with steady loads. Feature: Copper windings and insulation specifications support durability and thermal stability. The copper windings paired with 220 °C insulation enable robust performance under high-load conditions, while the 115 °C rise specification provides a clear thermal envelope for design margins. Business impact: improved impulse and short-circuit resilience, fewer thermal faults, and extended service life in demanding environments. Application: critical process lines and machine rooms where consistent voltage at scale matters.Feature: NEMA 2 enclosure with floor mounting and a substantial footprint. Indoor-only protection reduces exposure to dust and incidental moisture, while floor mounting simplifies integration into existing plant rooms and reduces vibration-related concerns. Business impact: faster installation, easier maintenance access, and a compact footprint for retrofit projects. Application: retrofit and new-build electrical rooms in manufacturing and distribution facilities.Feature: Voltage regulation with taps at 2 at +2.5% and 4 at -2.5%. The tap-changer capability maintains secondary voltage within tight tolerances under varying load, reducing voltage drop and equipment stress. Business impact: improved downstream equipment performance and longer service life. Application: facilities with variable loads or delicate downstream electronics.Feature: 3-phase, 225 kVA rating with 480 V to 208Y/120 V output and copper conductors. This configuration aligns with common industrial power distributions, enabling scalable capacity for growth. Business impact: streamlined procurement, standardization across sites, and efficient power management and distribution. Application: industrial facilities, data centers, and energy-intensive processes.

FAQs
This unit is designed for floor mounting in indoor spaces with a NEMA 2 enclosure. Install as a three-phase 480 V input to 208Y/120 V output using the 283B wiring connection. Plan for the 33.5 in length, 66.18 in height, 42.18 in width footprint and ensure adequate clearance for ventilation and service access.
The model is a 225 kVA, 60 Hz, three-phase transformer with 480 V primary and 208Y/120 V secondary. It uses copper windings, has a 115 °C insulation rise, and delivers a sound level around 55 dB. It also features a tap changer at 2 at +2.5% and 4 at -2.5% for voltage regulation.
Yes. With 225 kVA capacity, 60 Hz operation, and a DOE2016 Efficient profile, it suits steady loads typical of data centers and manufacturing facilities. The indoor NEMA 2 enclosure, floor mounting, and copper windings provide reliable, efficient power distribution while minimizing heat and energy costs.
It is UL Listed for safety, complies with DOE2016 Efficient energy standards, and references 127 CFR Part 431 Efficient in its catalog notes. These certifications support regulatory compliance, procurement approvals, and risk management across regulated industries.
Copper windings and robust NEMA 2 indoor design reduce thermal stress and extend service life, while DOE2016 efficiency lowers operating costs. The 225 kVA rating provides scalable capacity, and the floor-mounted footprint simplifies installation and maintenance access, contributing to a favorable total cost of ownership over the transformer’s life cycle.
