FAQs
Follow Eaton’s installation guidelines for floor or wall mounting, ensuring proper clearances, ventilation, and access to the 280BSB wiring terminals. Use appropriate lugs, adjust the +2.5% / -2.5% tap settings as needed, and verify insulation resistance before energizing. Confirm local code compliance and coordinate with your protection devices for safe, reliable operation.
Ideal for mid-scale, three-phase power distribution in manufacturing lines, process equipment, conveyors, and machine centers. Its 150 kVA rating, 480 V primary, and 208Y/120 V secondary support motor starting, drives, and loads requiring stable secondary voltage. The rugged NEMA 2 enclosure and copper windings provide durability in indoor plant rooms and protected spaces.
This unit is UL Listed for safety and meets energy efficiency requirements under DOE 2016, including 10 CFR Part 431 Efficient standards. It adheres to industry norms for dry-type transformers and includes features like an electrostatic shield for EMI reduction, contributing to regulatory and performance compliance in industrial facilities.
The RV48M28T4916CUSB is a three-phase transformer rated at 150 kVA with a 480 V primary and 208Y/120 V secondary, operating at 60 Hz. It uses copper windings and a 220 °C insulation class, with taps at +2.5% (2) and -2.5% (4) for voltage regulation, and a 280BSB wiring connection for compatible terminations.
ROI is driven by energy savings from DOE 2016 efficiency and reduced cooling loads, plus lower maintenance costs due to durable copper windings and robust enclosure. Regular insulating resistance checks, thermal monitoring, and periodic tap setting verification are recommended. The UL listing and protections embedded in the design help minimize unplanned outages and extend service life.
