Thomas Betts 54915BE Square Ring Terminal 1/2 Inch Stud

Product Description

The THOMAS BETTS 54915BE is a non-insulated square ring terminal designed for compression connections in electrical wiring applications. It features a copper contact body with a titanium nitride (TiN) plating for reliable conductivity and corrosion resistance. The terminal measures 3.68 inches in overall length and 1.36 inches in ring width, with a 0.18 inch material thickness. The 1/2 inch stud size makes it suitable for medium to heavy-duty termination work. Licensed electricians and electrical contractors install this type of terminal as a permanent, high-integrity lug connection on conductors where a ring-style termination is required at a fastened stud or bus connection point.

This terminal is used in residential, commercial, and industrial electrical installations where a non-insulated ring lug is required. Its square ring profile accommodates 1/2 inch studs and suits panel wiring, grounding applications, and equipment terminations. The compression connection type requires the use of an appropriate crimping tool to achieve a proper mechanical and electrical bond. The red color coding aids in identification during installation and inspection.

Key Features

• Non-insulated square ring profile for direct stud mounting at 1/2 inch stud size
• Compression connection type requires crimping for a secure, gas-tight termination
• Copper contact material provides low-resistance electrical conductivity
• Titanium nitride (TiN) contact plating for enhanced durability and corrosion resistance
• Red color coding for easy visual identification in wiring assemblies
• CSA Certified, UL Listed (UL File E9809), and RoHS Compliant

Compatibility

Designed as an OEM-style compression ring terminal for use in electrical panel, equipment, and grounding termination applications requiring a non-insulated square ring lug with a 1/2 inch stud size.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before terminating any conductors. Use a calibrated compression crimping tool rated for the conductor gauge and terminal type to ensure a proper mechanical connection. Do not attempt to re-crimp or reuse a terminal once it has been crimped onto a conductor.
