Overview

The ABB QCN50 Compression Stirrup Contax Filled is a precision-engineered copper connector designed for high-reliability applications in overhead and underground power distribution systems. This stirrup connector accommodates a wire range of 477 kcmil (18/1-4/0 ASCR) and 500 kcmil (4/0 Str. AWG), making it ideal for medium to high-voltage conductor terminations. The square-shaped copper stirrup ensures consistent compression and electrical continuity, while the Contax series design guarantees compatibility with industry-standard compression tools. Key applications include utility pole terminations, substation connections, and industrial power distribution where secure, long-lasting joints are critical. The QCN50 is manufactured from high-conductivity copper to minimize energy loss and withstand harsh environmental conditions, including temperature fluctuations and corrosive atmospheres. This compression stirrup is filled with oxide-inhibiting compound to prevent oxidation at the conductor interface, ensuring stable electrical performance over time. The 1/0 solid copper design provides additional mechanical strength and corrosion resistance, making it suitable for both new installations and maintenance operations. Compatible with standard compression tools, the QCN50 simplifies field installation while meeting ANSI C119.4 and IEEE 386 standards for overhead conductor connectors. Its compact square shape allows for efficient use of space in crowded termination points, reducing the risk of accidental contact or short circuits. For utility engineers and electrical contractors seeking a reliable, code-compliant solution for medium-voltage conductor terminations, the ABB QCN50 delivers consistent performance with minimal maintenance requirements.
