QC75YEKB - Hammond Power Solutions 0.75 kVA Encapsulated Dry Type Transformer 208/240/277V Primary 120/240V Secondary NEMA 3R

QC75YEKB

QC75YEKB is a 0.75 kVA encapsulated dry type distribution transformer from Hammond Power Solutions, designed for reliable single-phase power distribution in demanding environments. This unit features copper windings and an electrostatic shield for enhanced protection and performance. The transformer supports multiple primary voltage inputs (208V, 240V, 277V) with series connection and provides secondary output of 120/240V through parallel/series-N configuration. It is housed in a NEMA 3R enclosure for durability and safety, making it suitable for both indoor and outdoor installations.
