FAQs
When installing the N48M28F7521, plan for adequate clearances around the vented enclosure to ensure proper airflow and heat dissipation. The transformer weighs 430 lb and measures 21.13 in long, 24.88 in wide, and 36.88 in high, so allocate appropriate lifting equipment and space in a compliant mechanical room. Ensure connections meet 480-208Y/120V three-phase wiring standards and follow UL Listed safety guidelines.
The K-Factor nonlinear design optimizes magnetic flux and thermal behavior, reducing hotspot formation and improving transient response. This leads to lower cooling energy requirements and extended insulation life, particularly in facilities with frequent load swings. The result is more stable voltage regulation, improved uptime, and a lower total cost of ownership for industrial feeders.
Yes, the N48M28F7521 is well suited for mid-size distribution needs in both data centers and manufacturing environments. Its 75 kVA three-phase rating supports reliable power conditioning for critical equipment, while the vented design and UL Listed certification provide safety and compliance. Ensure alignment with your facility’s specific load profiles and space constraints for optimal results.
This transformer is UL Listed, indicating compliance with established electrical safety standards and reliability criteria. UL Listing facilitates procurement in regulated industries, reduces risk during commissioning, and supports audits and safety inspections. If your project requires additional certifications, consult the manufacturer’s datasheet for options on complementary classifications.
Key ROI drivers include robust cooling from the vented XFMR design, which minimizes thermal derating and extends service life under variable loads. Regular inspections should verify enclosure integrity, verify cooling paths, and confirm UL compliance remains intact after installation. With a 75 kVA rating and a durable build, the transformer offers predictable maintenance needs and steady performance over its lifecycle.
