Special features
K13
K-Factor nonlinear ventilated design offers superior heat management and reduced hot spots, lowering cooling loads and extending transformer life. This translates to measurable energy savings and lower maintenance costs in facilities with variable loading and tight space footprints. The DOE2016 Efficient compliance minimizes core and winding losses, improving overall system efficiency and reducing utility bills across peak and off-peak periods. UL Listed certification simplifies procurement, accelerates safety approvals, and enhances asset commissioning reliability in regulated industrial environments. The 150 kVA three-phase footprint and 480 V to 208Y/120 V wiring enable scalable power distribution, reducing panel count and wiring complexity in control rooms and machine centers. K13 thermal performance supports higher loading margins, enabling more predictable operation during transient demand. The robust 943 frame and ventilated construction ease installation in standard electrical spaces, while compatibility with Eaton’s Transformer Flex Center and related power-management solutions supports future upgrades and smarter energy use.

FAQs
Begin with ensuring adequate clearance for ventilation and access to the 283B wiring connection. Verify the panel space accommodates a 150 kVA, three-phase transformer with a 480 V primary and 208Y/120 V secondary. Mount using the frame footprint (943) and secure with appropriate hardware. Ensure electrical connections follow local codes, and perform insulation and continuity checks prior to energization. Refer to Eaton’s specification sheet for exact terminal torque and wiring schemes.
K-Factor nonlinear design addresses harmonic-rich currents by shaping losses and improving thermal performance under non-sinusoidal loads. The K13 feature indicates enhanced temperature rise management, supporting a 150 °C rise, which translates to higher loading tolerance. Combined with DOE2016 Efficient guidelines, this results in lower waste heat, reduced cooling requirements, and improved reliability during peak demand periods.
Yes. The N48M28T4921LS50 is a three-phase 150 kVA transformer with a 480 V to 208Y/120 V secondary, ideal for control panels, machine rooms, and process-distribution blocks. Its ventilated design and UL Listed certification help ensure safe operation in regulated environments. This unit supports scalable power delivery for mixed-control architectures while maintaining energy efficiency and compact enclosure footprint.
It carries UL Listed certification and complies with DOE2016 Efficient standards, indicating reliable safety performance and energy-saving operation. These certifications simplify procurement, accelerate regulatory approvals, and provide assurance during audits.
