Overview

The ABB RA877M Vinyl-Insulated Ring Terminal is a precision-engineered electrical termination solution designed for industrial, commercial, and residential applications requiring secure, corrosion-resistant connections. Manufactured by ABB Installation Products, this terminal combines electrolytic tin-plated copper with a high-quality PVC vinyl insulation rated for 600V and 221°F (105°C), meeting UL 94V-0 flammability standards and UL 486A/B/CSA certifications. The compact design measures 0.97 inches in length and 0.31 inches in width, with a maximum insulation diameter of 0.150 inches, making it ideal for tight spaces and high-density wiring systems. The #10 bolt hole accommodates standard mounting hardware, while the ring tongue design ensures a vibration-resistant connection that resists loosening under mechanical stress. Engineered for wire sizes ranging from #22 to #16 AWG, the RA877M features a continuously molded funnel entry that guides wires into the crimp barrel, reducing installation time and improving termination consistency. The red color coding enhances visual identification in complex wiring harnesses, reducing errors during assembly and maintenance. Supplied on Mylar tape in a 1,000-piece bulk pack, these terminals streamline inventory management and bulk installation projects, ensuring efficiency and reliability across high-volume applications. Compatible with standard crimp tools such as the ABB CA9 or CA-800EZ series applicators, the RA877M delivers consistent performance in grounding, bonding, and power distribution systems where durability and electrical integrity are critical.
