EX300T3H

In the Square D series, the EX300T3H transformer stands out with its three-phase configuration and operational power of 300 kVA. This unit is intended for environments operating at a network frequency of 60 Hz. It features a primary voltage of 480 V in a delta configuration, converting efficiently to a secondary voltage of 208Y/120 V.

Natural convection cooling allows the transformer to operate efficiently, maintaining a temperature rise of up to 150 degrees Celsius. The coils are made from aluminum, enhancing conductivity and reducing weight. For connection flexibility, it includes tap offs at a rate of 2.25% FCAN.

The transformer also boasts a Basix IMP level of 10 kV, ensuring it can handle significant electrical stress. The sound emission during operation is measured at 49 dB, indicating it is relatively quiet for industrial equipment. The unit's X/R ratio is recorded at 3.09, providing insight into its reactance to resistance during operation. Additionally, it can manage a let-through current of 16.7 kA, making it vital for safety and efficiency in high-current scenarios. With a %IZ of 5%, it offers considerable impedance for its rated capacity. This transformer is built to support industrial requirements with reliability and efficiency.
