Thomas Betts 54874BE Rectangle Ring Terminal 1/2 in Stud

Product Description

The THOMAS BETTS 54874BE is a non-insulated rectangle ring terminal designed for heavy-duty compression connections in electrical wiring applications. Measuring 5.51 inches in overall length and 1.41 inches in ring width, this terminal features a copper contact body with a titanium nitride (TiN) plating for enhanced conductivity and corrosion resistance. At 0.17 inches thick, the terminal accepts a 1/2-inch stud. Installation requires a proper compression crimping tool to achieve a reliable, gas-tight connection. This terminal suits licensed electricians and experienced electrical contractors working on high-ampacity conductor terminations.

This rectangle ring terminal is used in commercial and industrial electrical installations where large conductors must be terminated securely to bus bars, switchgear, panelboards, or similar equipment with 1/2-inch stud hardware. The non-insulated design is typical in applications where the termination point is enclosed within a listed enclosure or panel, and where the installer applies separate sleeving or heat-shrink as needed per local code requirements.

Key Features

• Non-insulated rectangle ring profile for high-ampacity terminations
• Compression connection type requires proper crimp tooling for a secure, gas-tight termination
• Copper contact material provides excellent electrical conductivity
• Titanium nitride (TiN) contact plating for added durability and corrosion resistance
• 1/2-inch stud size for compatibility with standard bus bar and switchgear hardware
• RoHS compliant construction

Compatibility

Designed as an OEM-style compression ring terminal for use with 1/2-inch stud electrical termination points in commercial and industrial panel, switchgear, and bus bar applications.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the circuit before making any terminations. Use a calibrated compression crimp tool rated for the conductor size and terminal type — do not use a standard ratchet or mechanical crimp tool not designed for this terminal. Verify conductor preparation, including proper strip length and absence of oxidation, before crimping.
