FAQs
The N48M28T3021 is designed for three-phase 480 V input with a 208Y/120 V secondary. Its FR940 frame supports straightforward mounting in standard electrical rooms and panelboards. Consider ensuring adequate ventilation for the ventilated design and verify clearances per Sizing and manufacturer guidelines. This enables a quick, compliant retrofit or new installation with minimal wiring changes.
K-Factor 13 indicates enhanced capability to withstand non-linear harmonics from modern VFDs and nonlinear loads. This reduces heating, improves voltage regulation, and lowers thermal stress compared with linear transformers. In practice, you’ll see longer winding life, reduced maintenance intervals, and improved reliability for equipment with variable-speed drives and switched-mode power supplies.
Yes, the unit is UL Listed and DOE2016 compliant, meaning it meets stringent safety and energy-efficiency standards applicable to industrial transformers. This simplifies compliance testing, streamlines procurement audits, and supports green energy initiatives within manufacturing sites, data centers, and process facilities without compromising performance or reliability.
This transformer is ideal for mid-size industrial facilities with non-linear loads—such as facilities using VFDs, presses, and mixed motor drives. Its 30 kVA capacity supports scalable distribution, while the 480 V to 208Y/120 V output matches common plant electrical architectures. It also suits retrofit projects aiming for DOE2016 efficiency and UL-listed confidence in critical operations.
The DOE2016 efficient design reduces standby and load losses, contributing to lower energy costs over the life of the asset. Combined with UL Listing and K-Factor 13 heat-management, maintenance intervals can be extended due to lower thermal stress. In ROI terms, expect reduced energy bills, fewer unwarranted outages, and a shorter payback period on capital projects.
