Eaton N48M47F30A Transformer – K-13 K-Factor, UL Listed
Part Number: N48M47F30A
Quick Summary
Eaton N48M47F30A Transformer delivers K-Factor nonlinear voltage transformation for three-phase power distribution in industrial plants. That approach addresses voltage drift, heat buildup, and space constraints that routinely hinder uptime and efficiency in equipment rooms and switchgear. Certified UL Listed for safety and reliability, this transformer supports robust industrial standards while meeting 60 Hz, three-phase power requirements. In practice, engineers appreciate the 2 taps at +2.5% FCAN and 4 taps at -2.5% FCBN for real-time voltage adjustments; the aluminum windings and electrostatic shield minimize EMI and heat. The unit’s WS38 weather shield and ventilated frame enable reliable operation in harsh environments, helping maintain uptime and lower maintenance costs.

FAQs
The N48M47F30A occupies a footprint that supports practical deployment in equipment rooms and enclosures. Dimensions include a depth of 16.5 inches, height of 30 inches, and width of 23 inches, with a frame size of 912B and weight around 310 pounds. Ensure clearance for ventilation and service access, and plan for ambient temperature limits up to the 115°C rise rating. This facilitates straightforward installation alongside compatible switchgear and panelboards in industrial settings.
WS38 provides weather protection for outdoor or harsh-environment installations. It helps resist moisture, dust, and chemical exposure, extending service life when the transformer is mounted in exterior or semi-exposed locations. When specifying for outdoor use, pair WS38 with appropriate enclosure or mounting schemes and verify enclosure ingress protection and ventilation considerations to maintain performance.
Voltage regulation is supported through taps: two at +2.5% and four at -2.5%, enabling real-time adjustment to counteract supply fluctuations. The unit operates at 60 Hz with a 480 V primary and 480Y/277 V secondary, delivering stable voltages to critical loads such as controls, drives, and lighting circuits. This design minimizes voltage sags and improves overall process reliability.
The N48M47F30A is UL Listed, ensuring compliance with recognized safety standards for industrial transformers. Warranty coverage follows Eaton policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first. Maintain documentation for warranty validation and refer to installation guidelines to optimize service life and inspection routines.
K-Factor nonlinear design improves harmonic handling and reduces EMI, which lowers heat-related losses and extends component life in power distribution networks. The aluminum windings and robust electrostatic shield contribute to durability, while 60 Hz operation and precise voltage taps reduce maintenance due to voltage irregularities. In turn, this translates to higher uptime, fewer sensor faults, and lower total cost of ownership in automation environments.
