Eaton Specification Sheet - N48M28F3316LS55
Feature → Business Impact → Application: K-Factor nonlinear ventilated design reduces loss and improves efficiency on heavy-duty loads, delivering lower operating costs and cooler operation in demanding environments. Application: control rooms, manufacturing lines, and distribution centers seeking reliable power conditioning with energy savings. Feature → Aluminum windings reduce weight and improve corrosion resistance, easing handling during installation and service while maintaining electrical performance under load. Application: indoor installations with limited crane time or frequent maintenance windows. Feature → NEMA 2 enclosure provides durable protection against dust and moisture, enabling floor-mounted setups in mechanical rooms without additional housing. Application: rugged environments where ingress protection is essential. Feature → Electrostatic shield modification minimizes EMI/VFI concerns, improving performance for nearby sensitive electronics and PLCs. Application: automation panels and robotics cells with tight signal integrity requirements. Feature → Tap size options (2 at +2.5%, 4 at -2.5%) allow voltage adjustment to match site conditions, reducing overshoot and improving bidirectional voltage stability. Application: facilities with fluctuating supply voltages or precise machine control needs. Feature → DOE 2016 and 10 CFR Part 431 efficiency compliance, combined with a 55 dB sound rating and 115 °C rise, translates to predictable energy use, quieter operation, and safer temperatures under load. Application: energy-conscious plant modernizations and new installations requiring regulatory alignment and predictable ROI.

FAQs
The unit supports a three-phase system with 480 V primary and 208Y/120 V secondary, operating at 60 Hz for broad compatibility with industrial power distribution and control panels. This enables straightforward integration with standard plant infrastructure and equipment.
The N48M28F3316LS55 is UL Listed and complies with DOE 2016 efficiency requirements as well as 10 CFR Part 431 efficiency standards, ensuring regulatory alignment, lower energy consumption, and long-term operational savings.
It uses a NEMA 2 enclosure, aluminum windings, and a 220 °C insulation rating, with an electrostatic shield to minimize EMI. These features support reliable operation in dusty, moist, or mechanically demanding spaces like floor-mounted panels and machine rooms.
Plan for a floor-mount arrangement (FR924 frame) with 283B wiring, ensure adequate clearance for ventilation, and verify that the site meets enclosure protection and insulation requirements. The unit’s WS40 compatibility supports outdoor-to-indoor protection in applicable spaces.
With DOE 2016 efficiency and 55 dB sound level, energy costs are reduced and audible impact minimized. Regular maintenance is typically routine (inspections, visual checks of enclosure and connections), and the robust design supports longer service intervals in demanding environments, improving total cost of ownership.
