Burndy QQA34-2N 400MCM500 Qiklug Terminal Connector

The Burndy QQA34-2N QIKLUG terminal connector is a heavy‑duty copper lug designed to terminate 400–500 kcmil copper conductors to equipment pads, bus bars, or switchgear. This two‑hole, twin‑clamping lug uses 1/2 in studs and a 1-3/4 in stud-hole spacing to deliver a secure, low‑impedance connection suitable for high‑current applications. As part of Burndy’s QIKLUG family, the QQA34‑2N employs dual clamps and requires two screws to tighten, ensuring consistent clamping force across both conductor paths. It is manufactured from a high copper alloy to maximize conductivity and mechanical strength in demanding environments. Ideal uses include large copper feeders, power distribution panels, and battery‑backed systems where reliable bolted terminations are essential, with the lug designed to accommodate two‑hole mounting on compatible equipment pads. This model is the 400–500 kcmil variant, explicitly rated for those conductor sizes, and is compatible with standard 1/2 in studs, providing a straightforward panel or accessory installation in industrial electrical infrastructure.
