EX75T3HFCU

The EX75T3HFCU from Schneider Electric is a transformer engineered for use with three-phase applications, boasting a robust operational power rating of 75 kVA. This unit works within a network frequency of 60 Hz and begins at a primary voltage rating of 480 V Delta. Its secondary voltage is configured at 208Y/120 V, permitting efficient energy distribution.

Heat dissipation is managed through natural convection, making it suitable for environments where extensive cooling measures are impractical. The transformer is also equipped with two tap-offs at 2.25% FCAN, allowing for fine-tuning of voltage to meet system needs. The temperature rise during operation is capped at a maximum of 150 degrees Celsius, ensuring safe performance under load.

This model utilizes aluminum for its coils, optimizing conductivity and durability while maintaining a low internal temperature. The Basix IMP level stands at 10 kV, providing an assurance of insulation strength. Sound emissions are measured at 47 dB, positioning it as a relatively quiet option in comparison to other transformers.

In terms of performance metrics, the unit features an X/R ratio of 1.09, which is vital for assessing the impedance characteristics of the transformer in use. The let-through current rate is recorded at 5.2 kA, assisting in providing a protective measure against short circuits and other electrical faults. Finally, the %IZ rating is set at 0.04%, reinforcing its efficiency in reactive power consumption. Overall, the EX75T3HFCU transformer is built to deliver reliable electrical performance in diverse industrial settings.
