Thomas Betts A18-6FL Locking Fork Terminal 600V 6 Stud

Product Description

The THOMAS BETTS A18-6FL is a non-insulated locking fork terminal designed for secure crimp connections in electrical wiring applications. Rated at 600 volts, this terminal features a copper contact body with a TiN (titanium nitride) plating for reliable conductivity and corrosion resistance. The locking fork design prevents the terminal from backing off a stud during vibration or thermal cycling, making it a preferred choice for panel wiring, machine control, and industrial installations where connection integrity is critical. Licensed electricians and experienced electrical technicians are the primary installers of this terminal type.

This terminal is suited for use in residential, commercial, and light industrial electrical applications where a crimp-style, non-insulated locking fork connection to a No. 6 stud is required. The 1/4-inch fork width and 3/4-inch overall length make it compatible with standard stud-mount terminal blocks, bus bars, and equipment lugs. It is packaged in a quantity of 100, supporting bench-stock use in panel shops and field service kits alike.

Key Features

• Locking fork design resists backing off under vibration and thermal cycling
• Copper contact material with TiN plating for conductivity and corrosion resistance
• 600-volt rating suitable for standard branch circuit and control wiring
• Crimp termination style for fast, consistent connections without solder
• Non-insulated design compatible with insulated or heat-shrink sleeve finishing
• Meets UL 486A, UL 486B, CSA 22.2, and RoHS compliance standards

Compatibility

Designed for use with No. 6 stud-mount terminals, bus bars, and equipment lugs requiring a 1/4-inch fork width locking crimp terminal in non-insulated configuration.

Installation Notes

Installation should be performed by a qualified electrician in accordance with NEC requirements and local codes. De-energize and lock out the circuit before terminating or removing any wiring connections. Use a calibrated ratcheting crimp tool appropriate for the wire gauge and terminal series to ensure a proper mechanical and electrical crimp. Do not over-crimp or re-crimp a terminal that has already been seated on a conductor.
