Eaton Specification Sheet - RV48M28T4516CUSB
Feature: Copper windings with 220 °C insulation support high current capability and low resistance. Business impact: Copper windings minimize resistive losses, improving efficiency and heat management in continuous-duty installations. Application: Ideal for 45 kVA, three-phase service in manufacturing lines, process equipment, and machine controls where steady voltage is critical. Feature: NEMA 2 enclosure with WS65 weathershield provides dust and moisture resistance. Impact: Enhances reliability in semi-damp plant areas and reduces enclosure upgrades. Application: Suitable for floor- or wall-mounted installations in factory floors, control cabinets, and instrument panels where environmental exposure is a concern. Feature: DOE 2016 efficient rating and 10 CFR Part 431 compliance ensure high-efficiency operation. Impact: Lower losses during operation, easier regulatory reporting, and reduced energy costs. Application: Good fit for facilities pursuing energy-performance goals in dry-type transformers for new builds or retrofits. Feature: Secondary MCCB JGE3160FAGC with an electrostatic shield strengthens short-circuit protection and reduces EMI. Impact: Improves protective coordination and electrical noise mitigation, decreasing downstream protection requirements. Application: Critical in machine centers and switchgear assemblies needing integrated protection and reliable startup. Feature: Floor- or wall-mount mounting with 280BSB wiring and adjustable tap settings (+2.5%, -2.5%). Impact: Accelerates installation and enables precise voltage regulation to protect sensitive equipment. Application: Flexible for factory automation, control cabinets, and service panels with varied layouts.

FAQs
The transformer is floor- or wall-mounted and uses a 280BSB wiring connection. Plan for a 21.13 in depth, 24.88 in width, and a 45 kVA three-phase load with a 480 V primary and 208Y/120 V secondary. Ensure clearance for ventilation and service accessibility, and account for the 150 °C rise rating during steady-state loading.
Key specs include 45 kVA rating, three-phase, 60 Hz frequency, 480 V primary, and 208Y/120 V secondary. Tap settings are 2 at +2.5% and 4 at -2.5%. Copper windings with 220 °C insulation support reliable continuous operation, while the NEMA 2 enclosure provides basic enclosure protection.
The unit features a NEMA 2 enclosure and WS65 weathershield, offering dust and moisture resistance suitable for many indoor industrial spaces. For outdoor or harsher exposure, additional protection or enclosure upgrades may be considered, but this model is designed for dependable performance in typical manufacturing environments.
This transformer is UL Listed and includes DOE 2016 efficiency compliance, along with 10 CFR Part 431 efficiency alignment. These certifications support regulatory compliance, energy performance reporting, and safe operation in modern industrial facilities.
The secondary MCCB (JGE3160FAGC) and electrostatic shield reduce downstream protection needs and EMI concerns, improving reliability and reducing maintenance. DOE 2016 efficiency and UL listing contribute to energy savings and risk mitigation, delivering faster payback through lower energy consumption and enhanced uptime.
