Product Description
The Burndy KA29U is a high-capacity, universal terminal lug designed for heavy-duty electrical terminations in panelboards, switchboards, and transformer secondary connections. Precision-machined from high-strength 6061-T6 extruded aluminum alloy, this mechanical lug is engineered to handle massive feeders up to 250 kcmil. Its robust, single-hole design ensures a permanent, high-integrity electrical bond in demanding industrial environments.
Every KA29U features a premium electro-tin plated finish to inhibit oxidation and maintain exceptionally low contact resistance. This dual-rated (AL9CU) terminal is certified for use with both copper and aluminum conductors, providing total flexibility for commercial power distribution and grounding projects.
