Thomas Betts 54116 Square Ring Terminal 1/2 Inch Stud

Product Description

The THOMAS BETTS 54116 is a non-insulated square ring terminal designed for compression-style electrical connections in demanding trade applications. It features a copper contact body with a titanium nitride (TiN) plating for improved conductivity and corrosion resistance. Measuring 3.2 inches in overall length and 1.41 inches in ring width, it is sized for a 1/2-inch stud and has a contact thickness of 0.17 inches. Electricians and electrical contractors install this terminal when making permanent, high-integrity ring connections in panel work, industrial wiring, and commercial electrical assemblies where insulation is handled separately.

This terminal is suited for commercial and industrial electrical installations where compression tooling is used to create secure, gas-tight terminations. Its square ring profile provides stable seating on stud-mounted bus bars, equipment terminals, and grounding points. The non-insulated design is appropriate for applications where heat-shrink or sleeving insulation is applied independently, or where bare terminations are required by the installation configuration. It is commonly installed by licensed electricians working on panel boards, motor control centers, and heavy equipment wiring.

Key Features

• Square ring profile for stable, flush seating on 1/2-inch studs
• Compression connection type for reliable, gas-tight terminations with proper crimping tooling
• Copper contact material for high conductivity
• Titanium nitride (TiN) contact plating for enhanced corrosion and wear resistance
• Non-insulated construction allows independent insulation selection by the installer
• UL Listed, CSA Certified, and RoHS Compliant

Compatibility

Designed as an OEM-style compression ring terminal for use with 1/2-inch stud terminations in commercial and industrial electrical installations where square ring terminals are specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the circuit before making any termination. Use only the compression tooling specified for the terminal series to achieve a properly formed crimp. Do not over-crimp or apply heat directly to the terminal body, as this may compromise the TiN plating and contact integrity.
