Thomas Betts 54913BE Square Ring Terminal 1/2 Inch Stud

Product Description

The THOMAS BETTS 54913BE is a non-insulated square ring terminal designed for compression-style electrical connections in heavy-duty wiring applications. The terminal features a copper contact body with a titanium nitride (TiN) plating for enhanced conductivity and corrosion resistance. At 3.15 inches in overall length and 1.13 inches in ring width, with a contact thickness of 0.14 inches, this terminal is sized for secure, low-resistance terminations on 1/2-inch stud hardware. It meets CSA, UL Listed, and RoHS compliance standards. Electricians and maintenance technicians use this part where a reliable, code-compliant ring terminal is required in industrial and commercial panel or equipment wiring.

This square ring terminal is suited for use in commercial and industrial electrical installations where compression-style terminations are specified. The 1/2-inch stud size and square ring geometry are common in switchgear, control panels, bus bar connections, and heavy equipment wiring. The non-insulated design allows direct visual inspection of the crimp after installation and is appropriate where post-installation sleeving or heat-shrink protection is applied by the installer.

Key Features

• Square ring profile fits 1/2-inch stud hardware for positive mechanical retention
• Copper contact material provides high conductivity at the termination point
• TiN (titanium nitride) contact plating resists oxidation and wear
• Compression connection type requires no soldering and produces a gas-tight crimp
• Non-insulated construction allows visual crimp inspection and custom sleeving
• CSA Certified, UL Listed (File E9809), and RoHS Compliant for code-required installations

Compatibility

Designed as an OEM-style compression ring terminal for industrial and commercial electrical applications requiring a non-insulated square ring terminal on 1/2-inch stud connections.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements. De-energize and lock out the circuit before terminating or inspecting any connections. Use a calibrated compression crimping tool rated for the wire gauge and terminal type to ensure a proper gas-tight crimp. Do not over-crimp or re-crimp a terminal that has already been seated, as this can compromise contact integrity.
