Eaton Specification Sheet - N48M28T75AFEELS50
Feature: K-Factor nonlinear design with KT-13 classification improves harmonic handling for high-load three-phase systems. Business Impact: This reduces overheating risk, extends insulation life, and lowers maintenance costs across the plant. Application: Ideal for facilities with harmonic-rich loads like robotics, drives, and mixed-load switchgear. Feature: Voltage taps for +2.5% and -2.5% adjustments enable precise voltage balancing. Business Impact: Tighter regulation minimizes voltage sag, improves equipment performance, and reduces energy waste. Application: Plants with fluctuating mains or long feeders benefit from quick, field-adjustable compensation. Feature: NEMA TP-1 efficient design delivers low sound (around 50 dB) and UL Listed certification. Business Impact: Supports compliance with noise limits, enhances workplace comfort, and lowers regulatory risk. Application: Control rooms, switchgear spaces, and outdoor enclosures where quiet operation matters. Feature: Weathershield WS19 with fungus-proof construction supports outdoor and harsh-environment installations. Business Impact: Extends life in exposed locations, reduces material replacement costs, and eases enclosure planning. Application: Outdoor substations, manufacturing exteriors, and outdoor automation cabinets. Feature: Aluminum coil, 283B wiring, 916A frame, and 220 °C insulation provide robust, install-ready hardware. Business Impact: Lighter yet strong for easier handling, reliable performance under elevated temperatures, and simpler installation in tight spaces. Application: Standard three-phase transformer deployments in modern industrial plants. Feature: 75 kVA rating with 480 V primary and 208Y/120 V secondary delivers scalable power for evolving load profiles. Business Impact: Supports growth without hardware swaps, reduces total cost of ownership, and enables flexible automation architectures. Application: Facilities transitioning from legacy gear to energy-efficient, code-compliant power distribution.
