Thomas Betts 54165-TB Ring Terminal 3/0 Awg Compression

Product Description

The THOMAS BETTS 54165-TB is a non-insulated rectangle ring terminal designed for compression connections on 3/0 AWG conductors. It features a copper contact body with a titanium nitride (TiN) plating, which provides corrosion resistance and reliable conductivity at the mating surface. The terminal measures 2.35 inches in length and 0.92 inches in width, with a 1/2-inch stud hole to suit heavy-duty fastening points. This type of lug is installed by licensed electricians and maintenance technicians working on high-ampacity circuits in industrial, commercial, or utility applications where a bare, uninsulated termination is acceptable.

This ring terminal is suited for large-conductor termination tasks such as grounding connections, bus bar attachments, and panel feeder terminations. The compression connection method requires a calibrated crimping tool sized for 3/0 AWG to achieve a cold-weld bond between the conductor and the terminal barrel. The orange color coding assists with quick AWG identification during installation and inspection. Applications span commercial electrical panels, switchgear, motor terminations, and similar high-current wiring work.

Key Features

• Non-insulated rectangle ring design with 1/2-inch stud hole for heavy-duty fastening
• Compression connection method delivers a gas-tight crimp for low-resistance, long-term conductivity
• Copper contact body with TiN (titanium nitride) plating for corrosion resistance
• Sized for 3/0 AWG conductors with a 0.13-inch barrel wall thickness
• Orange color coding for fast AWG identification in the field
• CSA Certified, UL Listed, and RoHS Compliant

Compatibility

Designed as an OEM-style compression ring terminal for 3/0 AWG copper conductors requiring a non-insulated, rectangle-style lug with a 1/2-inch stud opening.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the NEC and any applicable local electrical codes. De-energize and lock out the circuit before terminating or removing any conductor. Use a compression crimping tool properly rated and calibrated for 3/0 AWG to ensure a complete, gas-tight crimp — do not use a mechanical or set-screw tool as a substitute. Inspect the barrel for complete conductor seating before making the final crimp.
