Overview

The ABB RL9751 Nylon Insulated Large Ring Terminal is a high-reliability electrical termination solution engineered for industrial power distribution, machinery, and control panels. This terminal features a tin-plated copper body with a durable nylon insulation sleeve, providing corrosion resistance and electrical insulation up to 600V per UL 486A/B standards. The RL9751 accommodates wire sizes from 3/0 AWG with a maximum insulation diameter of 0.680 inches, ensuring compatibility with heavy-duty conductors in high-current applications. The 1/2-inch bolt hole enables secure mechanical fastening to bus bars or terminal blocks, while the ring tongue design prevents accidental disconnection under vibration. The internal barrel incorporates serrations for optimal wire contact and tensile strength, and the metal insulation grip sleeve crimps directly to the wire jacket for strain relief in dynamic environments. With a UL 94 HB flammability rating and a maximum operating temperature of 221°F (105°C), this terminal is certified for use in harsh industrial settings. The bright red color coding simplifies circuit identification and inventory management. Ideal for power distribution panels, motor controls, and renewable energy systems, the RL9751 delivers consistent performance where reliability is critical.
