The 3TW1DG20 kit contains three individual aluminum mechanical lugs and the necessary mounting hardware. These lugs are "Dual Rated" (AL/CU), meaning they are safe for use with both aluminum and copper conductors. They are typically used on the "Line" (top) or "Load" (bottom) side of Siemens DG-Frame breakers to simplify field wiring without the need for specialized compression crimp tools.
