Overview

The ABB RK9731 Nylon Insulated Large Ring Terminal is a heavy-duty electrical termination solution designed for industrial and commercial applications requiring robust, vibration-resistant connections. Manufactured by ABB Installation Products, this terminal features a tin-plated copper barrel with a brazed seam for superior conductivity and corrosion resistance, ensuring long-term reliability in harsh environments. The 2.52-inch length and 0.93-inch width provide ample space for secure bolt fastening, while the 3/8-inch bolt hole accommodates standard hardware for easy installation. The yellow nylon insulation offers high visibility and is rated for 600V applications per UL 486A/B, with a maximum insulation temperature of 221°F (105°C) and UL 94 HB flammability compliance. The internal barrel features serrations for maximum wire retention and tensile strength, while the metal insulation grip sleeve crimps to the wire insulation, providing strain relief and protection against vibration-induced damage. Ideal for wiring ranges from 2/0 AWG, this terminal is compatible with standard crimping tools such as the CT-100, CT-1550, CT-1551, CT-2300/ST, CT-2500/L, and UP14ZLW. Trusted by professionals in power distribution, industrial machinery, and renewable energy systems, the RK9731 delivers consistent performance in critical electrical connections where durability and safety are paramount.
