Burndy K11A30U Mechanical Lug

Burndy K11A30U is an aluminum universal terminal lug engineered for two conductors terminated through a single 5/16 in stud and one mounting hole. Crafted from high-strength extruded aluminum alloy and electro tin-plated to minimize contact resistance, it is dual-rated for aluminum and copper conductors and accepts two conductors from 6 AWG up to 300 kcmil on a 5/16 in stud with two set screws, making it suitable for panelboards, switchgear, and other distribution equipment. The lug's overall footprint measures about 3.00 in long by 1.02 in wide by 2.03 in high, with a bolt hole size of 5/16 in, and it uses Allen-style screws for secure clamping; it is rated for use up to 194°F (90°C). Designed for both aluminum and copper conductors, the K11A30U supports aluminum/copper conductor ranges that cover typical service entrance and feeder connections, providing a compact, dual-rated termination for space-constrained installations. The combination of a one-hole, two-conductor design and tin-plated hardware ensures reliable electrical continuity in panel-based applications while maintaining compatibility with Burndy’s universal lug standards.
