The EX150T3H model from Schneider Electric's Square D series represents a durable solution for electrical transformations. Weighing 933 pounds (423.20 kg), it boasts dimensions of 1031 mm in height, 827 mm in width, and 855 mm in depth. Designed as a 3-phase dry-type transformer, it operates with a primary voltage input of 480 volts delta and delivers a secondary voltage output of 208Y/120 volts.

This unit's impedance is rated at 4.20%, which contributes to its efficiency of up to 98.83% at a 35% load level, while maintaining a temperature of 75°C. Notably, the aluminum coil material enhances the transformer's capabilities. The temperature rise of this device can reach up to 150°C, while its insulation system withstands temperatures up to 220°C.

The basic impulse level (BIL) is rated at 10 kV, ensuring the transformer can effectively handle electrical surges. Moreover, it operates at a sound level of 47 dB, which is quieter than the threshold set by NEMA ST-20 standards. Cooling is facilitated by natural air convection, making this transformer both efficient and reliable in various operational environments.
