Overview

The ABB A18-4 Non-Insulated Ring Terminal (SKU: A18-4) is a high-conductivity copper terminal designed for secure, long-lasting electrical connections in industrial and commercial applications. Constructed from electrolytic copper and tin-plated for corrosion resistance, this terminal ensures reliable performance in demanding environments. It accommodates wire ranges from #22 to #16 AWG and features a #4 bolt hole for attachment to studs or busbars. With dimensions of 0.75 inches in length, 0.31 inches in width, and 0.27 inches in stock thickness, the A18-4 provides a substantial contact area for stable connections. The non-insulated design, combined with a brazed seam construction, prevents barrel splitting during crimping and ensures a robust, tamper-resistant connection that requires complete screw removal for disconnection. Rated for 600V and a maximum operating temperature of 105°C, this terminal is ideal for control panels, machinery, electrical distribution systems, and general wiring where dependable termination is critical. The A18-4 is manufactured with a precision-engineered barrel that maintains consistent crimp integrity, reducing the risk of loose connections or intermittent faults. Its tin plating enhances conductivity while providing superior resistance to oxidation and environmental contaminants, extending service life in harsh conditions. The terminal’s #4 bolt hole is compatible with standard M4 hardware, ensuring compatibility with common industrial fasteners. The 0.75-inch length and 0.31-inch width are optimized for compact installations where space constraints are a factor, while the 0.27-inch stock thickness provides the necessary mechanical strength for high-stress applications. The A18-4 is packaged in quantities of 100 units per box, making it suitable for both small-scale and bulk installation projects, with each terminal individually tested for dimensional accuracy and electrical continuity before shipment.
