DM051KKC - Hammond Power Solutions 3PH 51kVA 480V Drive Isolation Transformer Copper Coil NEMA 3R

DM051KKC

DM051KKC is a three-phase drive isolation transformer designed for industrial applications requiring reliable power distribution and protection for variable speed drives. This unit features a copper coil construction and is rated for 51kVA at 480V primary and secondary, making it suitable for demanding environments. The DM051KKC is engineered to withstand overcurrent up to 150% of rated load for 60 seconds or 200% for shorter durations, ensuring robust performance under stress. It includes a neutral terminal for field connection and is built with a 220°C (150°C rise) insulation system for enhanced durability. The transformer is floor or wall mountable and features a NEMA 3R enclosure for protection against environmental factors.
