DM075NJK - Hammond Power Solutions 75 kVA 575V Drive Isolation Transformer 3 Phase Wall Mount

DM075NJK

DM075NJK is a 75 kVA drive isolation transformer from Hammond Power Solutions designed for industrial applications requiring reliable voltage isolation and conditioning.

This transformer features a 575 VAC primary voltage and a 460Y/266 VAC secondary voltage, operating at 60 Hz frequency. It is a three-phase unit with a wall mounting type, suitable for indoor and outdoor environments when used with the appropriate mounting kit or drip plate. The unit meets UL and CSA short circuit withstand requirements and includes a coil-mounted thermal warning switch for enhanced protection. Typical impedance ranges from 3 to 6%, and the transformer is built to handle the rugged demands of AC and DC variable speed drives.
