FAQs
This unit is designed for a 480 V primary and 208Y/120 V secondary in a three-phase configuration. It uses a 280BPBSB wiring connection and copper windings, ensuring reliable compatibility with common industrial switchgear and panelboards while delivering the required voltage transformation in a single package.
The RV48M28T4916CUPBSB is UL Listed and DOE 2016 Efficient, with catalog notes aligning to 10 CFR Part 431 requirements. These certifications support safety, regulatory compliance, and energy efficiency in commercial and industrial installations, reducing risk and potential retrofit costs.
Yes. The design features a NEMA 2 enclosure for indoor protection and a three-phase 150 kVA rating with a vented transformer configuration, making it well-suited for motor control centers and service entrances where space, protection, and reliability are critical.
The unit is floor-mounted with a footprint defined by 31.5 in length, 34.5 in width, and ~59.5 in height. These dimensions support compact installation in indoor electrical rooms, with a practical tall profile for alignment with other equipment and service clearances.
With copper windings and a 150 °C rise rating, expect robust thermal performance under load. Plan periodic inspections of the primary MCCB integration, verify enclosure integrity (NEMA 2), and monitor for any signs of overheating or wear in the copper windings, ensuring continued compliance with UL and DOE efficiency requirements.
