FAQs
Installers should plan for outdoor or damp-location placement given the NEMA 3R enclosure, allowing it to be mounted in exterior electrical rooms or yard areas. Ensure adequate clearance for ventilation, access to taps, and compatibility with 208 V delta input wiring. The CASE B+ frame supports sturdy mounting on concrete pads or dedicated enclosures, while 208Y/120 V secondary wiring should be routed to the distribution panels with proper protection devices.
The unit is a three-phase, 45 kVA transformer rated for 60 Hz. Primary voltage is 208 V delta, with a secondary of 208Y/120 V. It features voltage taps: 2 AT +2.5% FCAN and 4 AT -2.5% FCBN to accommodate nominal voltage variations and maintain downstream equipment performance.
Yes. The N29M28F4516-US is designed with a NEMA 3R enclosure and aluminum windings that enable reliable outdoor service, rain or shine. Its rugged construction, combined with DOE2016 efficiency, makes it well-suited for outdoor plants, loading docks, and exposed electrical rooms where space and durability are critical.
The transformer carries UL Listed certification and complies with DOE2016 efficiency requirements as part of 10 CFR Part 431. These certifications ensure safety, energy compliance, and alignment with federal efficiency programs, which can simplify regulatory reviews and project approvals.
The K-Factor nonlinear ventilated design emphasizes advanced cooling and efficient heat management, reducing thermal stress on windings. This translates to longer insulation life, lower thermal aging, and reduced maintenance cycles, especially in high-load or hot environments commonly found in continuous-Process and automation lines.
