FAQs
Installers should verify adequate panel space for the unit’s 36.88 inch height and 24.88 inch width, ensure clear ventilation clearance, and plan for 480-208Y/120 wiring and terminal access. Use UL Listed installations per local codes and Eaton’s guidelines, consulting the N48M28T3021LS42 datasheet for terminal block arrangements and mounting clearances.
Key specs include a 30 kVA rating, three-phase configuration, and 480-208Y/120 secondary. The K-Factor nonlinear design enhances transient resilience to harmonics, reducing overheating and extending insulation life. This results in steadier voltage, improved motor and drive performance, and lower cooling and maintenance requirements in demanding environments.
Yes. The 30 kVA three-phase profile and vented XFMR construction make it well-suited for data centers and manufacturing lines where stable voltages are essential and non-linear loads are common. UL Listed certification further supports safe integration into critical infrastructure while enabling reliable operation under peak demand and transient events.
The transformer carries UL Listed certification, a baseline safety standard for electrical equipment in industrial settings. This certification simplifies procurement approvals, reduces risk during audits, and supports consistent compliance with safety codes across plant maintenance programs and new installations.
The combination of a robust vented design, stable voltage delivery, and reduced cooling loads lowers ongoing maintenance needs and energy consumption. Over time, this translates to lower total cost of ownership, improved uptime, and faster return on investment for mid-size industrial facilities adopting consistent, safe, and reliable power distribution.
