FAQs
This transformer is designed for floor or wall mounting in upright orientation. Plan for a stable concrete base or wall mounting kit, ensure proper clearance for ventilation, and provide convenient access to the 283B wiring connection. The NEMA 2 enclosure supports indoor applications, with attention to service access and ventilation per site conditions.
The unit has a 480 V primary and a 440Y/254 V secondary. It features taps at 2 at +2.5% and 4 at -2.5% to accommodate small voltage adjustments under varying load conditions. This allows tighter voltage regulation for motors and drives without replacing components, improving performance and reducing wear on connected equipment.
Yes. The N48M35T7516CU is UL Listed and meets DOE 2016 efficiency requirements. It also aligns with 10 CFR Part 431 Efficient standards, aiding regulatory compliance and qualifying for energy efficiency programs during procurement and audits.
Best suited for heavy-load, three-phase power distribution in manufacturing lines, machine panels, and control rooms. The 75 kVA rating, copper windings, and K-Factor 13 design support efficient motor starting, load stability, and reduced heat generation, while the NEMA 2 enclosure provides reliable indoor protection in harsh environments.
The transformer measures 31.5 in in length, 34.5 in in width, and 51 in in height, weighing 1133 lb. Plan for a stable mounting surface, adequate space for access and ventilation, and a service path for wiring (283B). Consider the shielded construction and the need for proper clearance to comply with safety and maintenance requirements.
