Feature 割 Business Impact 割 Application. Eaton N48M28B4516LS50 employs K-Factor 13 nonlinear technology to reduce transformer losses under non-linear loads, improving overall system efficiency and cooling reliability in dense panel layouts. This translates to measurable energy savings, lower heat rejection, and quieter operation on the shop floor, enabling tighter control of ambient conditions around critical equipment. Application: panel boards and machine controls where non-linear loading is common and space is at a premium. Feature Aluminum windings reduce weight and improve heat dissipation compared with copper-only designs, offering easier handling during installation and lower support requirements in retrofit projects. Business Impact: lower installed weight, simplified mounting, and improved serviceability. Application: retrofits in constrained spaces or overhead installations. Feature DOE 2016 Efficient and 10 CFR Part 431 compliance ensures regulatory alignment, reducing risk during audits and procurement cycles. Business Impact: predictable compliance costs, potential energy incentives, and smoother project approvals. Application: facilities targeting energy compliance programs. Feature NEMA 2 enclosure with FR943 frame and WS60 weathershield provides rugged protection for indoor environments and upgrades to outdoor-rated protection where permitted. Business Impact: extended equipment life, reduced enclosure-related downtime, and simplified wiring in harsh facilities. Application: industrial environments with dust, moisture, or incidental exposure. Feature 50 dB sound level and 80 °C rise enable quieter operation and safe thermal margins in busy electrical rooms. Business Impact: improved worker comfort, reduced noise-related hazards, and fewer thermal constraints on adjacent equipment. Application: open factory floors and control rooms near production lines. Feature 283B wiring connection and 2 at +2.5%, 4 at -2.5% tap options ease voltage adjustment during commissioning. Business Impact: faster, lower-risk commissioning and easier on-site voltage matching to sensitive loads. Application: systems requiring precise secondary voltage tuning.

FAQs
This transformer uses a floor or wall mounting footprint with a rugged NEMA 2 enclosure and FR943 frame. Plan for 31.5 in depth, 51 in height, 34.5 in width, and a 1007 lb weight. Ensure adequate ventilation and access for wiring, with 283B wiring connections and voltage-tap adjustors (+2.5% / -2.5%).
DOE 2016 efficiency reduces core and winding losses under typical industrial loads, lowering no-load and load losses compared to older models. Over the life of the unit, this translates to noticeable energy savings, cooler enclosure temperatures, and lower cooling requirements in HVAC systems, contributing to lower total cost of ownership.
Yes. It is a three-phase, 45 kVA transformer with a 480 V primary and 208Y/120 V secondary, designed for control panels, switchgear, and machine tools requiring reliable, stepped-down voltage in industrial environments.
The unit is UL Listed for safety and complies with DOE 2016 efficiency and 10 CFR Part 431 (2016 Efficient) requirements. These certifications support regulatory approvals, procurement, and energy-performance reporting for industrial facilities.
Leverage the aluminum windings for durability and straightforward maintenance, keep sound levels around 50 dB to minimize workplace noise, and use the tap settings to fine-tune output. Regular inspections of the FR943 frame, WS60 shield, and enclosure seals help sustain performance and reduce unexpected downtime.
