Eaton Specification Sheet - X48M28T7516CUNON
Feature: Copper windings and 220 °C insulation reduce I2R losses and enable higher temperature rise tolerance, improving efficiency under load. Business impact: lower energy consumption translates to noticeable operating cost savings and cooler equipment rooms, extending component life. Application: ideal for continuous-duty environments such as data centers, automation panels, and manufacturing lines where peak efficiency supports reliability and uptime. Feature: 75 kVA, three-phase design with 480 V delta primary and 208Y/120 V four-wire secondary delivers flexible power distribution and straightforward panel integration. Business impact: simplifies circuit design, reduces voltage drop on sensitive loads, and accommodates common European/US voltage variants in a single unit. Application: control panels, machines, and building services where clean, balanced power is essential. Feature: Harmonic mitigation with zero phase shift minimizes added distortion in the system, improving power quality for nonlinear loads. Business impact: lowers audible noise and thermal stress on downstream equipment, helping to prevent premature failures. Application: drives, rectifiers, UPS interfaces, and other non-linear loads in industrial environments. Feature: Rugged physicals—NEMA 2 enclosure, FR942 frame, copper windings, and 220 °C insulation—designed for floor mounting and long service life. Business impact: durable installation in workshop floors or service bays with minimal protection needs. Application: factory floors, loading docks, and equipment rooms in harsh conditions; compatible with standard 200X wiring and space constraints. Feature: DOE 2016 Efficient and UL Listed with Eaton warranty provide regulatory compliance and peace of mind. Business impact: reduces compliance risk, lowers total cost of ownership, and supports service contracts. Application: facilities subject to energy codes and quality management programs in manufacturing, data centers, and process industries. Installation and compatibility notes: This unit uses 200X wiring connections, is designed for floor mounting, and fits standard service clearances. The 75 kVA rating supports scalable load growth, while the 0° phase shift minimizes phase-related issues during upgrades. In retrofit projects, its compact footprint can simplify cabinet replacements and minimize downtime.
