Eaton N48M28F15CULS42 K-Factor nonlinear ventilated transformer - UL Listed
Part Number: N48M28F15CULS42
Quick Summary
K-Factor nonlinear ventilated transformer is a robust power solution for three-phase industrial power distribution. Engineers often grapple with voltage fluctuations, heat buildup, and noisy operation in demanding automation environments. UL Listed certification confirms safety and compliance across installation sites, while the 115°C rise rating and copper windings support reliability in harsh conditions. This transformer's 15 kVA rating, 480 V primary and 208Y/120 V secondary, combined with the K-13 design and electrostatic shield, offers predictable performance for control panels, machinery, and data-center peripheral power. With 2 at +2.5% and 4 at -2.5% taps, 60 Hz operation, compact frame 912B, and manufactured by Eaton, it reduces field adjustments and helps optimize energy efficiency and lifecycle cost.

Selling Policy 25-000 - Distribution and Control Products and Services
Feature → The K-13 design, ventilated construction, copper windings, and electrostatic shield deliver superior thermal management and EMI protection. Benefit → This translates to lower hotspot risk, improved reliability, and reduced downtime in demanding automation environments. Application → Ideal for large control panels and machine feeders where stable voltage and clean power are critical. Feature → The 15 kVA, three-phase configuration with a 480 V primary and 208Y/120 V secondary aligns with common plant distribution schemas. Benefit → Streamlined panel design, fewer transformers required per line, and efficient space utilization. Application → Power intelligent automation racks and multi-load panels in manufacturing facilities. Feature → Tap changes of 2 at +2.5% FCAN and 4 at -2.5% FCBN enable precise voltage regulation. Benefit → Improved voltage tolerance across load variations, reducing equipment stress and energy waste. Application → Sites with fluctuating supply or sensitive loads like CNC machines and robotics. Feature → Low sound specification at 42 dB supports quieter operation in office-adjacent facilities and noise-sensitive environments. Benefit → Enhanced worker comfort and compliance with noise limits during continuous operation. Application → Data centers, production lines, and maintenance areas near occupied spaces. Feature → 115°C rise rating and copper windings provide robustness under thermal load and peak demand. Benefit → Higher thermal resilience translates to longer service life and lower preventive maintenance costs. Application → Continuous duty applications in hot industrial settings. Feature → Weathershield WS38 compatibility and a robust 912B frame support flexible installation and outdoor/indoor use. Benefit → Easier field integration, weather exposure considerations, and standardized mounting fit. Application → Outdoor-rated installations or harsh factory environments where enclosure options vary. Warranty and safety notes → A one-year warranty from installation or 18 months from shipment provides risk mitigation for procurement and maintenance planning. Certifications → UL Listed confirms compliance with safety standards across regions, supporting procurement approval and traceability.
