FAQs
Plan for mounting on a suitable frame (914D) with weather protection (WS39) if outdoor or damp environments are present. Verify primary and secondary voltages (480 V / 480Y/277 V), use correct taps (+2.5% / -2.5%), and ensure adequate clearance for ventilation and service access. Follow UL Listed guidelines and Eaton installation notes to maintain warranty and safety compliance.
This transformer delivers 45 kVA at 60 Hz in a three-phase configuration with a 480 V primary and 480Y/277 V secondary. It features aluminum windings, an electrostatic shield, a 914D frame, and taps at +2.5% FCAN and -2.5% FCBN. Temperature rise is rated at 80 °C, and it is UL Listed, with WS39 weather shielding for environmental protection.
Yes. Its 45 kVA rating, three-phase configuration, and precise voltage regulation via taps support reliable power distribution in data centers. The K-Factor nonlinear design helps manage harmonic currents common in server loads, while the aluminum windings and electrostatic shield enhance longevity and protection in continuous-duty environments.
