Thomas Betts 54965BE Square Ring Terminal 3/0 Awg

Product Description

The THOMAS BETTS 54965BE is a non-insulated square ring terminal designed for high-current compression connections in electrical wiring applications. Built with a copper contact and titanium nitride (TiN) plating, it provides reliable conductivity and corrosion resistance at the termination point. Rated for 3/0 AWG wire, this terminal accepts a 1/2-inch stud and measures 2.7 inches in overall length with a ring width of 0.92 inches. It is installed by licensed electricians and electrical contractors working on power distribution, industrial wiring, and heavy-gauge conductor terminations where a secure, low-resistance lug connection is required.

This terminal is suited for commercial and industrial electrical installations where 3/0 AWG conductors are terminated to busbars, lugs, or equipment stud connections. The compression-style connection requires a calibrated crimping tool to achieve a proper cold-weld bond between the terminal barrel and the conductor. The orange color coding assists with wire gauge identification during installation and inspection. It meets CSA, UL, and RoHS requirements, making it appropriate for use in code-compliant electrical work across North American jurisdictions.

Key Features

• Compression connection type for a gas-tight, high-integrity crimp on 3/0 AWG conductors
• Copper contact with TiN plating for improved conductivity and oxidation resistance
• Square ring geometry for secure stud seating on 1/2-inch hardware
• Non-insulated design allows inspection of the crimp and suits high-temp or tight-clearance installs
• Orange color coding aids wire gauge identification per field and panel inspection standards
• UL Listed, CSA Certified, and RoHS Compliant for use in code-governed installations

Compatibility

Designed as a compression-style ring terminal for 3/0 AWG conductors terminating to 1/2-inch stud hardware, suitable for use in commercial and industrial power distribution applications requiring UL Listed and CSA Certified lug connections.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize and lock out the circuit before terminating conductors. Use a calibrated compression crimping tool rated for 3/0 AWG to achieve a proper cold-weld crimp — do not use mechanical set-screw tools as a substitute for compression tooling. Verify stud torque requirements per the equipment manufacturer before final assembly.
