Follow local codes for safe enclosure mounting.
The RV48M28B4516CUSB delivers 45 kVA, three-phase, with a 480 V primary and 208Y/120 V secondary, rated for 60 Hz operation and an 80 °C rise. It uses copper windings, 220 °C insulation, and a 942SD frame. Tap settings are 2 at +2.5% and 4 at -2.5%, supporting voltage regulation for sensitive loads.
Yes. It complies with DOE 2016 Efficient guidelines and is UL Listed, ensuring both energy efficiency and safety. The DOE efficiency designation helps reduce operating costs over the life of the equipment, while UL Listing provides recognized safety certification when installed in compliant panels and systems.
The built-in secondary MCCB JGE3150FAGC provides coordinated overcurrent protection, reducing wiring complexity and enabling faster fault clearance. This integration simplifies panel layouts, lowers installation time, and improves overall protection reliability for automated machinery and process control applications.
ROI is driven by space savings from a compact footprint, reduced wiring and protection wiring errors, and improved energy efficiency with DOE 2016 compliance. The integrated MCCB lowers parts count and commissioning time, while UL Listing supports faster regulatory approvals, resulting in lower total installation and maintenance costs over the product life cycle.
