FAQs
Installers should plan for a 75 kVA transformer with 480 V primary and 208Y/120 V secondary in a NEMA 2 enclosure. Check the mating footprint of the 914D frame and provide adequate clearance for ventilation. Use the two +2.5% taps and four -2.5% taps to adjust voltage within the panel’s acceptable range, ensuring proper distribution to downstream loads and minimal voltage drop.
Key specs include 75 kVA rating, 60 Hz, 480 V primary, 208Y/120 V secondary, aluminum coil, and 2 taps at +2.5% plus 4 taps at -2.5%. The transformer rises to 150 °C with a 200 °C insulation system. Taps enable voltage regulation under load, helping maintain stable outputs for sensitive drives and control electronics.
Yes. The CV48M28T75EE is designed for general purpose distribution in control panels and machine automation. Its 75 kVA rating, 480 V to 208Y/120 V conversion, and adjustable taps support reliable power delivery to motors, drives, and controllers while complying with UL and CSA safety standards and providing robust enclosure protection for industrial environments.
The transformer is UL Listed and CSA labeled, indicating safety and reliability across recognized standards. Its NEMA TP-1 efficiency designation signals energy efficiency in continuous operation, while the NEMA 2 enclosure offers practical protection in typical indoor plant environments. These certifications facilitate code compliance, audits, and smoother installation approvals.
Eaton provides a one-year warranty from installation or eighteen months from shipment, whichever occurs first. Ongoing support includes access to Eaton datasheets and catalog resources. The ROI comes from improved reliability, reduced downtime, and energy-efficient operation under NEMA TP-1, along with voltage regulation via taps that minimize tripping and equipment wear.
