FAQs
Plan for floor mounting in a protected area given the unit's 34.5 in depth, 42.18 in width, and 74.8 in height, with an approximate weight of 2828 lb. Ensure adequate clearance for ventilation and servicing access. The integrated NGS3120KSEC MCCB simplifies wiring to local panels, while the 280BPB wiring connection is compatible with standard low-voltage distribution schemes.
The RV48M28T3316CUPB delivers 300 kVA, three-phase power at 60 Hz. It features a primary 480 V delta and a secondary 208Y/120 V, with a voltage rating of 480 Vac-208Y/120 Vac and a 150 °C rise. Tap adjustments are available: 2 taps at +2.5% and 4 taps at -2.5%, supporting voltage regulation under varying load conditions.
This unit is UL Listed and complies with DOE2016 Efficient performance and 10 CFR Part 431 (2016) Efficient standards. These certifications validate safety, energy efficiency, and regulatory compliance, reducing risk in procurement, ensuring smoother project approvals, and aligning with corporate sustainability goals.
The built-in NGS3120KSEC MCCB provides overcurrent protection directly at the transformer, reducing external wiring and separate protective devices. This simplifies installation, speeds commissioning, and improves protection coordination with downstream feeders, which can lower fault-related downtime and engineering effort in plant startups.
With copper windings, a 220 °C insulation rating, and a robust NEMA 2 enclosure, the unit supports long service life in demanding environments. DOE2016 efficiency lowers energy losses, contributing to reduced operating costs. The UL listing and shielded design also translate to lower inspection overhead and improved total cost of ownership over the life of the facility.
