Eaton Specification Sheet - N47M48B1516CU
The K-Factor nonlinear ventilated design with copper windings minimizes harmonic currents, reducing heat buildup and extending transformer life. This translates to improved uptime and lower cooling costs in electrical rooms, benefiting critical automation lines and data centers. With a 15 kVA rating in a three-phase configuration and a 60 Hz operating frequency, it supports mid-range industrial feeders and panelboard banks, while the 480Y/277 V primary and 480 V secondary voltages enable seamless integration into common plant distribution schemes. Copper windings and a 220 °C insulation rating provide robustness against rising temperatures, enabling reliable operation in warm environments and offering an 80 °C rise specification for predictable thermal performance. An NEMA 2 enclosure offers indoor protection, and floor or wall mounting flexibility simplifies retrofits; wiring connection B47MD2 supports straightforward terminations. DOE 2016 efficiency and 10 CFR Part 431 compliance reduce energy waste and regulatory risk, while UL Listed certification adds installation assurance. Tap settings of 2 at +2.5% and 4 at -2.5% enable precise voltage regulation under varying load. The one-year warranty (or eighteen months from shipment) improves ROI by mitigating early-life failures, and its NEMA ST-20 sound performance suits typical plant environments.
