FAQs
Plan for a heavy-duty installation: 1735 lb transformer with dimensions 24.67 in depth, 31.44 in width, and 56.17 in height. Mount on a rigid base compatible with Frame 917, provide adequate clearance for cooling, and connect 3-phase 480 V primary to the distribution panel with 208Y/120 V secondary. Utilize the voltage taps for compensation during commissioning to ensure stable operation.
Key specs include a 150 kVA three-phase rating at 60 Hz, 480 V primary, 208Y/120 V secondary, copper windings, and an electrostatic shield. Temperature rise is 115 °C, with a sound level of about 47 dB. It provides taps of +2.5% FCAN and -2.5% FCBN and includes WS34 weather shielding for enhanced durability.
Yes. The WS34 weather shield supports outdoor or harsh-environment installations, while copper windings and electrostatic shielding improve reliability in electrically noisy settings. Ensure proper enclosure protection and ventilation to maintain the 115 °C rise rating and preserve EMI performance in outdoor or indirect-exposure applications.
The N48M28F49CULS47 is UL Listed, meeting established safety and electrical-code requirements for industrial power distribution. This certification supports safe integration into control panels and distribution assemblies. For regional or additional standards, consult Eaton’s official documentation and catalog updates.
Maintenance is typically minimal due to copper windings and robust core construction. The unit carries Eaton’s warranty—one year from installation or eighteen months from shipment, whichever comes first. The high-efficiency design and EMI shielding reduce energy losses and downtime, delivering a favorable return on investment over the transformer’s service life.
