Product Description
The Square D DCC C-17 (Model DU-600) is a high-capacity, dual-port mechanical terminal lug engineered for demanding electrical distribution. Specifically designed for use with Square D / Schneider Electric equipment, this lug allows for the termination of two large-diameter conductors to a single mounting point. It is a critical component for high-amperage feeders, neutral assemblies, and heavy-duty switchgear applications.
Fabricated from high-strength 6061-T6 aluminum alloy, the DU-600 is dual-rated (AL9CU) for both aluminum and copper conductors. Its robust construction and compact parallel-port design make it the ideal solution for high-density wiring environments where reliability and space efficiency are paramount.
