Thomas Betts 18RA-10FL Locking Fork Terminal 10 Stud 600V

Product Description

The THOMAS BETTS 18RA-10FL is a locking fork terminal designed for secure, vibration-resistant electrical connections in demanding field and panel wiring applications. The locking fork design grips the stud to prevent accidental disconnection, making it well-suited for environments where vibration or movement is a concern. This terminal features partial vinyl insulation in red for easy wire gauge identification, a crimp connection method, and a copper contact with titanium nitride (TiN) plating for improved conductivity and corrosion resistance. Rated at 600 volts, it meets UL 486A, UL 486B, and CSA 22.2 standards. Electricians and panel technicians install this terminal when a reliable, code-compliant ring-style alternative with locking capability is required.

This terminal is used in residential, commercial, and light industrial wiring where a No. 10 stud size is present. Typical applications include control panels, motor connections, grounding points, and terminal strips where wire terminations must stay secure under mechanical stress. The red color coding indicates compatibility with wire gauges in the 18 AWG range, helping technicians sort and verify connections quickly during installation or inspection.

Key Features

• Locking fork design prevents terminal from backing off the stud during vibration or handling
• Partial vinyl insulation in red for visual wire gauge identification
• Copper contact with TiN plating for reliable conductivity and corrosion resistance
• Crimp connection type for fast, consistent field termination
• Rated 600 volts with UL Listed status under UL File E9809
• UL 94 V-0 rated insulation material for flame resistance
• Compliant with CSA 22.2, UL 486A, UL 486B, and RoHS requirements

Compatibility

Designed for use with No. 10 stud size termination points in standard crimp-style wiring applications rated up to 600 volts.

Installation Notes

Licensed electricians should install this terminal using a calibrated ratcheting crimp tool sized for the applicable wire gauge to ensure a gas-tight, code-compliant connection. De-energize and lock out the circuit before terminating or inspecting any connections, per NFPA 70E safe work practices. Do not use pliers or uncalibrated tools in place of a proper crimp tool, as this can result in a cold crimp that fails under load or vibration.
