Overview

The ABB RA2257ML Vinyl Insulated Locking Fork Terminal is a precision-engineered electrical connector designed for secure and long-lasting wire terminations in industrial, commercial, and control panel applications. This terminal features a tin-plated copper body with durable vinyl insulation, ensuring excellent electrical conductivity and corrosion resistance. The locking fork design clamps onto the wire with consistent pressure, preventing loosening from vibration or thermal cycling. With a wire range of #22 to #16 AWG and a #10 bolt hole, the RA2257ML accommodates common industrial wiring sizes while providing a stable mechanical connection. The 0.97-inch length and 0.29-inch width allow for compact installations in tight spaces, while the red color coding simplifies circuit identification. Supplied on a left-hand reel, this terminal is optimized for automated or manual wire processing workflows. Typical applications include motor control centers, PLC enclosures, HVAC systems, and industrial machinery where reliable, vibration-resistant terminations are critical. The combination of copper conductivity, tin plating for solderability, and vinyl insulation makes this terminal suitable for both low-voltage control circuits and power distribution systems up to the rated wire size.
