Burndy QQA312N is a heavy-duty twin-clamping copper terminal lug from the QIKLUG family, engineered to join 250–350 kcmil copper conductors to equipment pads or bus bars with a two-clamp arrangement and 1/2 in studs. It features two mounting holes and two screws for a secure two-point connection, with 1.75 in stud spacing (1-3/4 in). The copper alloy lug is unplated and RoHS compliant, designed for one-wrench installation, and specifies a tight torque of 325 in-lbs for proper clamping. This model supports copper cable applications in heavy electrical assemblies where high current capacity and robust, compact connectors are required.
