Overview

The ABB RF4-38 Nylon Insulated Large Ring Terminal is a precision-engineered electrical termination solution designed for industrial-grade applications requiring robust, vibration-resistant connections. Manufactured by ABB Installation Products, this terminal features a tin-plated copper conductor with a durable nylon insulation jacket, ensuring long-term reliability in harsh environments. The 3/8" bolt hole accommodates standard mounting hardware, while the 4 AWG wire range supports heavy-duty applications. The 1.84" length and 0.62" width provide optimal space efficiency without compromising mechanical strength. The internal barrel serrations guarantee maximum tensile strength and secure wire contact, while the metal insulation grip sleeve crimps to the wire jacket for strain relief in high-vibration scenarios. UL 486A/B and CSA certified for up to 600V applications, this terminal meets stringent safety standards with a UL 94 HB flammability rating and a maximum insulation temperature of 221°F (105°C). Ideal for control panels, machinery wiring, and electrical distribution systems, the RF4-38 combines durability, compliance, and ease of identification with its bright yellow color coding.
