DM440JC - Hammond Power Solutions 3-Phase Drive Isolation Transformer 440 kVA 460V Delta Primary 230Y/133V Secondary Aluminum Wound

DM440JC

DM440JC is a 3-phase drive isolation transformer from Hammond Power Solutions, designed for industrial applications requiring reliable power distribution and isolation. This transformer features a 460V delta primary with dual 2.5% taps and delivers a 230Y/133V secondary voltage at 440 kVA capacity. Constructed with aluminum windings, it is built to withstand overcurrent up to 150% of rated load for 60 seconds or 200% for 30 seconds, making it suitable for demanding environments. The DM440JC is engineered for durability and performance, with a robust design that supports industrial drive systems. It is commonly used in applications where harmonic mitigation and electrical isolation are critical. The transformer is designed for floor mounting and is enclosed in a Type 3R enclosure for protection against environmental factors.
