FAQs
Ensure proper mounting in a compliant enclosure or on a suitable frame, maintain adequate clearance for ventilation, and connect to the 480 V three-phase supply. Set taps as needed (+2.5% or -2.5%), verify 60 Hz operation, and follow UL/NEMA TP-1 installation guidelines to achieve rated performance and minimize thermal stress.
Key specs include 112.5 kVA rating, primary 480 V, secondary 208Y/120 V, three-phase, 60 Hz, temperature rise 115 °C, and taps at +2.5% / -2.5%. Coil material is aluminum, frame 916A, with a low noise level of 47 dB and WS19 weather shield.
Yes. The N48M28F12EELS47 is designed for industrial power distribution with harmonic management (K-Factor), tight voltage regulation via taps, and low audible noise. Its UL Listed and NEMA TP-1 compliance, plus weather protection, make it appropriate for data centers adjacent to other equipment and demanding manufacturing environments.
The unit is UL Listed and NEMA TP-1 compliant, ensuring safety, reliability, and compatibility with industry standards. These certifications simplify procurement for regulated facilities and support safer installation and operation in critical environments.
Expect improved uptime due to robust cooling and reduced harmonic heating, lower cooling costs thanks to efficient design, and a predictable maintenance profile backed by a one-year warranty (or 18 months from shipment). The combination of reliability, compliance, and efficient operation drives total cost of ownership down over time.
