FAQs
Plan a three-phase 480 V feed to the primary side and route the secondary to 208Y/120 V circuits. Use the recommended 283B wiring connection and ensure a suitable enclosure for the 916A frame. Consider the WS19 weather shield for outdoor or harsh environments and reference Eaton’s spec sheet for exact mounting clearances and torque values.
The unit is a 75 kVA, three-phase transformer with 480 V primary and 208Y/120 V secondary, rated for 60 Hz operation. It includes taps at +2.5% and -2.5% for voltage regulation, a 150°C rise with a 200°C insulation system, and an aluminum winding. These specs indicate strong capacity, stable output under load variations, and resilience in demanding environments.
Yes. The N48M28T75EECS is described as a K-Factor nonlinear ventilated transformer, designed to mitigate harmonic distortion and manage heat from non-linear loads. This means better voltage regulation and reduced stress on downstream equipment, making it suitable for drives, inverters, and other harmonic-heavy machinery.
The product data lists Certifications as 'Contact Manufacturer,' and catalog notes indicate NEMA TP-1 efficiency. For region-specific approvals like CE or UL, contact Eaton or your authorized distributor to obtain current certificates and applicable test reports or declarations of conformity.
Benefits include improved power quality, reduced downtime, and energy efficiency from NEMA TP-1 compliance. Maintenance focuses on periodic inspection of windings, shield integrity, and enclosure protection; the WS19 shield and aluminum windings can lower lifecycle costs. A higher initial investment is often offset by longer service life, fewer outages, and streamlined spare-parts planning.
