Burndy N40 4STR GRAY DIE Compression Lug

Burndy N40-4STR Gray Die compression lug is a copper compression terminal engineered for four-stranded #4 AWG copper conductors. As part of Burndy’s N40 family, the lug carries a gray die designation that signals the compatible crimp profile for this conductor size and strand configuration, enabling a reliable, pressure-tight termination. The four-strand construction and copper material deliver solid conductivity and corrosion resistance in typical electrical installations, where the lug terminates a conductor to a lug interface in panels, enclosures, and power-distribution gear. The N40-4STR model name identifies this lug as a four-strand, #4 AWG copper option, aligned with Burndy’s color-coded die system to help ensure the correct crimp is applied for this size. This precise labeling supports proper selection and reduces the risk of mismatched terminations in electrical assemblies built with Burndy components.
