Overview

The ABB M250-38 Non-Insulated Tubular Ring Terminal is a precision-engineered solution for heavy-duty electrical connections in industrial, commercial, and utility applications. Designed for copper conductors ranging from 4/0 AWG to 250kcmil, this terminal features a 3/8-inch bolt hole and a 2.40-inch overall length, ensuring compatibility with high-current systems. The tin-plated copper construction delivers superior conductivity and corrosion resistance, meeting UL and CSA standards for up to 2000V per UL 486A/B. Key features include a brazed seam that prevents barrel splitting during crimping, internal barrel serrations for optimal wire contact and tensile strength, and internal beveling for quick, error-free wire insertion. With a maximum operating temperature of 302°F (150°C), the M250-38 is ideal for power distribution, motor controls, switchgear, and renewable energy systems where reliability under vibration and thermal stress is critical. This 5-pack terminal is packaged for convenience and efficiency, allowing contractors and maintenance teams to stock essential components for large-scale projects or routine repairs. Compatible with standard crimping tools, the M250-38 ensures consistent, long-lasting connections in applications requiring high current-carrying capacity and mechanical stability. Whether used in industrial machinery, electrical panels, or utility substations, this terminal provides the durability and performance needed for critical electrical infrastructure.
