FAQs
This unit is floor-mounted with dimensions of 32 in depth, 50.5 in width, and 66 in height, weighing 2700 lb. It uses a NEMA 3R enclosure with RH6 weather protection, making outdoor or semi-outdoor installation feasible. Ensure adequate clearance around the transformer and proper ventilation for cooling, with three-phase 480 V delta primary feeding a 208Y/120 V secondary at 60 Hz.
The device is rated at 300 kVA with a 480 V primary and a 208Y/120 V secondary, operating at 60 Hz. Tap sizes are +2 at 2.5% FCAN and -4 at 2.5% FCBN, providing voltage regulation for fluctuating supply conditions and downstream equipment.
The transformer is UL Listed and DOE 2016 Efficient compliant, with 10 CFR Part 431 (2016) Efficient notes. These certifications ensure safety, energy efficiency, and regulatory alignment for facilities aiming to meet federal efficiency standards and occupational safety requirements.
Ideal for data centers, manufacturing floors, distribution panels, and process facilities requiring reliable 480 V to 208Y/120 V distribution. Its 300 kVA rating, low 55 dB noise, and rugged NEMA 3R enclosure support durable operation in indoor rooms and outdoor equipment yards common to industrial plants.
Expect durable aluminum windings, 150 °C rise insulation, and a 55 dB sound profile for quieter operation. The combination of DOE 2016 efficiency, UL listing, and a robust enclosure lowers energy losses and maintenance cycles, delivering lower total cost of ownership over a multi-year horizon.
