Overview

The ABB RM757 Nylon Insulated Large Ring Terminal (SKU: RM757) is a high-reliability electrical termination solution engineered for heavy-duty industrial applications. This terminal features a robust tin-plated copper construction with a durable nylon insulation sleeve rated for UL 486A/B compliance up to 600V. The RM757 accommodates wire sizes up to 250MCM (250 kcmil) with a maximum insulation diameter of 0.868 inches, ensuring compatibility with thick insulation cables. The 1/2-inch bolt hole provides secure mechanical fastening, while the ring tongue design resists loosening in high-vibration environments such as power distribution panels, industrial machinery, and control systems. The internal barrel incorporates serrations for maximum tensile strength and wire retention, and the metal insulation grip sleeve crimps directly to the wire jacket for strain relief and protection against vibration-induced damage. The blue color coding simplifies identification in wiring harnesses. UL 94 HB flammability rated with a maximum insulation temperature of 221°F (105°C), this terminal is CSA certified and designed for continuous operation in harsh conditions. Recommended crimping tools include the CT-100, CT-1550, CT-1551, CT-2300/ST, CT-2500/L, and UP14ZLW series applicators for consistent, high-integrity terminations.
