FAQs
Installation starts with confirming a 480 V three-phase service and a compatible 480Y/277 V secondary circuit. Mount the unit in a suitably rated enclosure using the 914D frame, connect LV and HV bushings per Eaton’s wiring diagrams, and ensure proper ventilation. Use the WS39 shield in exposed locations and verify tap settings for voltage regulation (+/- 2.5%).
The transformer delivers 45 kVA at 60 Hz in a three-phase configuration. Primary: 480 V; Secondary: 480Y/277 V. It employs aluminum windings, an electrostatic shield, and a ventilated design with a 150 °C rise. Tap settings include 2 taps at +2.5% FCAN and 4 taps at -2.5% FCBN for voltage adjustments.
Yes. The unit supports WS39 Weathershield options and a ventilated frame suitable for demanding environments. The combination of aluminum windings, electrostatic shield, and weather shielding helps maintain reliability in outdoor or rugged installations while meeting UL safety standards.
The N48M47T45A is UL Listed, signaling compliance with recognized safety standards for electrical equipment. This certification helps streamline compliance during audits and reduces supplier risk. When combined with robust insulation and protective features, it supports safer operation in industrial power distribution networks.
With aluminum windings and a durable ventilated design, maintenance needs are focused on periodic inspection of connections, insulation, and enclosure integrity. The 150 °C rise rating and WS39 shielding contribute to higher uptime, lower cooling costs, and improved lifecycle value, delivering favorable total cost of ownership in automation and manufacturing settings.
