FAQs
The N48M28T4521LS45 is a 45 kVA three-phase transformer configured for 480-208Y/120 output. It weighs 658 lb and has dimensions of 24 in depth, 30.5 in width, and 36.88 in height. Plan for adequate ventilation, clearance, and a suitable enclosure or transformer room that can support its footprint and weight. It integrates with standard Eaton distribution layouts and should be wired per its UL Listed safety guidelines.
K-Factor nonlinear refers to the transformer’s ability to tolerate non-sinusoidal currents without excessive losses or overheating. This design reduces harmonic distortion, improves cooling under heavy nonlinear loads, and helps maintain stable voltages. For facilities with variable-speed drives or other nonlinear loads, this translates to longer equipment life and more predictable operation.
Yes, the N48M28T4521LS45 is UL Listed, indicating safety compliance for industrial installations. This certification simplifies procurement, reduces validation time, and supports regulatory alignment in factories, data centers, and automated production lines.
Absolutely. Its 45 kVA rating, three-phase configuration, and nonlinear tolerance make it suitable for data centers and manufacturing environments with high noncontinuous loading. The vented design supports effective cooling, and the compact footprint aids installation in space-constrained electrical rooms or panel assemblies typical of automation facilities.
The vented XFMR construction and K-Factor nonlinear design help keep temperatures lower under nonlinear loads, reducing thermal stress and extending component life. With UL safety certification and a robust build, maintenance intervals can be longer and downtime reduced, contributing to lower total cost of ownership in busy production environments.
