Overview

The ABB RK737 (SKU: RK737) is a nylon-insulated large ring terminal engineered for secure, high-reliability electrical connections in industrial power distribution, control panels, and machinery. Constructed from tin-plated copper, it delivers superior conductivity and corrosion resistance, ensuring long-term performance in demanding environments. The terminal features internal barrel serrations for enhanced wire grip and maximum tensile strength, while the molded funnel entry insulator provides strain relief and protection against vibration-induced disconnections. The ring tongue design prevents accidental loosening, requiring full screw removal for disassembly. With a wire range of 3/0 AWG and a 3/8-inch bolt hole, it accommodates heavy-duty conductors. The terminal measures 2.60 inches in length and 0.93 inches in width, with a maximum insulation capacity of 0.765 inches. The bright yellow color coding ensures quick identification during installation and maintenance. Ideal for power distribution systems, industrial equipment, and high-vibration applications where dependable termination is critical. The terminal's nylon insulation provides dielectric strength and resistance to moisture, chemicals, and abrasion, further enhancing its durability in harsh conditions. Its tin plating ensures compatibility with aluminum and copper conductors, reducing the risk of galvanic corrosion. The 3/0 AWG wire range supports high-current applications, making it suitable for motor control centers, switchgear, and renewable energy systems. The 3/8-inch bolt hole allows for secure fastening with standard hardware, while the 2.60-inch length provides ample clearance for tool access during installation. The 0.93-inch width ensures compatibility with most terminal blocks and busbars, and the 0.765-inch maximum insulation accommodates thick wire jackets without compromising performance.
