Overview

The ABB RF10731U Nylon Insulated Large Ring Terminal is a precision-engineered electrical termination solution designed for high-reliability industrial applications. This terminal features a 90-degree bend for space-saving installations and accommodates 4AN wire sizes (0.204–0.250 inch diameter) with a maximum insulation thickness of 0.380 inches. Constructed from tin-plated copper with a brazed seam, it ensures superior conductivity, corrosion resistance, and mechanical integrity during crimping. The yellow nylon insulation provides dielectric strength up to 600V (UL 486A/B and CSA certified) and a flammability rating of UL 94 HB, with a maximum operating temperature of 221°F (105°C). The terminal includes a metal insulation grip sleeve that crimps to the wire jacket, offering strain relief and protection in high-vibration environments. Internal barrel serrations guarantee optimal wire contact and tensile strength, while the continuously molded design ensures consistent terminations when used with compatible crimping tools like the CA9 or CA-800/EZ series. With a compact footprint (1.80 inches long, 0.82 inches wide) and a 3/8-inch bolt hole, the RF10731U is ideal for power distribution panels, control systems, and heavy-duty machinery where secure, vibration-resistant connections are critical. Trust ABB Installation Products for dependable components that meet stringent industry standards.
