Burndy YA34A5 Lug Terminal For Copper And Aluminum Conductors

Burndy YA34A5 is a two-hole, long-barrel compression lug from the YA series, engineered for 500 kcmil copper or aluminum conductors, with a 3/8-inch bolt stud and 1-inch center-to-center hole spacing that facilitates a robust two-point connection in large-diameter cables. The AL-CU dual-rating designation means the lug is suitable for both copper and aluminum conductors, and the aluminum terminal is tin-plated (AL9CU) with a prefilled PENETROX flux and an end cap to support sealed terminations. UL/CSA listed with a 90°C temperature rating and a voltage rating up to 35 kV, it is designed for high-current distribution and service applications, including feeders and large motors, where reliable compression connections are critical in electrical installations. As part of Burndy's YA-TC compression family, the YA34A5 emphasizes ease of installation on spacious high-amperage runs, with features such as a long barrel entry and two-hole pattern that align with standard equipment terminals and provide stable mechanical performance under load.
