Eaton Specification Sheet - N48M28T49EELS45
Feature → Business Impact → Application: The K-Factor nonlinear design mitigates harmonic distortion, improving power quality and protecting sensitive downstream equipment, which reduces unplanned downtime on CNC machines and HVAC systems in manufacturing plants. This translates to higher productivity and lower maintenance costs in industrial automation environments. Feature → Business Impact → Application: The ventilated aluminum coil design supports a high 150°C rise insulation system and robust thermal performance, enabling longer service intervals and fewer deratings in hot plant spaces, especially in outdoor or bays with elevated ambient temperatures. Feature → Business Impact → Application: Tap settings with 2 at +2.5% and 4 at -2.5% provide precise voltage regulation, minimizing voltage drop along feeders and improving load stability for critical processes in data centers and process lines. Feature → Business Impact → Application: Electrostatically shielded construction and low 45 dB sound output reduce EMI and noise-related disturbances, facilitating compliance with plant noise limits and enabling installation closer to control rooms or laboratories. Feature → Business Impact → Application: Weathershield WS34 and a compact 150 kVA, three-phase package offer reliable outdoor readiness and straightforward integration with existing power distribution layouts in industrial facilities. Feature → Business Impact → Application: UL Listed and NEMA TP-1 compliance underpin safety, reliability, and standardized performance, simplifying procurement, audits, and maintenance planning in highly regulated manufacturing and distribution environments.
