Thomas Betts 54914BE Square Ring Terminal Compression

Product Description

The THOMAS BETTS 54914BE is a non-insulated, compression-style square ring terminal designed for high-integrity electrical connections in demanding trade applications. The terminal measures 3.5 inches in overall length and 1.25 inches in ring width, with a 0.1500-inch barrel thickness and a 0.5-inch stud size. The contact is solid copper with a titanium nitride (TiN) plating, which improves wear resistance and surface conductivity at the connection point. This terminal is installed by licensed electricians and maintenance technicians working on power distribution, industrial control panels, and heavy-gauge wire terminations where a bare, mechanically sound connection is required.

The 54914BE is suited for commercial and industrial electrical work where non-insulated terminals are specified, such as panel wiring, grounding applications, and bus bar connections. The compression connection method requires a proper ratcheting or hydraulic crimp tool to achieve a gas-tight termination. The white color coding assists with visual identification during installation and inspection. This terminal is appropriate for use in environments governed by NEC requirements for mechanical lug and ring-type terminations on copper conductors.

Key Features

• Non-insulated design for use where insulation is applied separately or not required
• Compression connection provides a reliable, gas-tight mechanical and electrical bond
• Copper contact with TiN plating for improved corrosion and wear resistance
• 0.5-inch stud size accommodates standard heavy-duty fastener hardware
• Square ring geometry supports consistent seating on bus bars and panel studs
• CSA Certified, UL Listed (UL File E9809), and RoHS Compliant

Compatibility

Designed as an OEM-style compression ring terminal for use with copper conductors requiring a 0.5-inch stud size termination in commercial and industrial electrical installations.

Installation Notes

Installation must be performed by a qualified electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating or removing any ring terminal. A calibrated compression crimp tool rated for the conductor gauge and terminal series must be used — hand crimping is not acceptable for compression-style terminals. Inspect the completed crimp for full barrel engagement and verify stud torque per the equipment manufacturer's specifications.
