Thomas Betts A18-10FL Locking Fork Terminal 600V

Product Description

The THOMAS BETTS A18-10FL is a non-insulated locking fork terminal designed for secure, vibration-resistant electrical connections in panel wiring, control systems, and equipment terminations. It uses a crimp connection method and is rated for 600 volts. The terminal body is made from copper with a tin nitride (TiN) contact plating, which improves corrosion resistance and contact reliability. The locking fork design prevents accidental disconnection from the stud, making it well-suited for applications where terminals may be exposed to movement or vibration. Licensed electricians and panel builders typically install this style of terminal using a calibrated crimping tool matched to the wire gauge range.

This terminal is used in residential and commercial electrical applications where a #10 stud connection is required. The red color coding helps identify wire gauge during installation and inspection. Its non-insulated construction makes it appropriate for use in terminal blocks, motor controls, switchgear panels, and other enclosures where post-crimp insulation or sleeving is applied separately. The small overall length of 0.75 inches suits tight wiring runs and compact panel layouts.

Key Features

• Locking fork design prevents pull-off from stud under vibration or mechanical stress
• Non-insulated copper body with TiN contact plating for corrosion resistance
• Crimp connection method for fast, reliable termination
• Rated for 600 volts
• Red color coding for wire gauge identification
• Meets UL 486A, UL 486B, UL 94 V-0, CSA 22.2, and RoHS compliance standards

Compatibility

Designed for use with #10 stud sizes. Suitable for crimp termination applications in electrical panels, motor controls, and control wiring assemblies where a non-insulated locking fork terminal is specified.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements. De-energize the circuit completely before terminating or inspecting connections. Use a calibrated ratcheting crimping tool appropriate for the conductor size to ensure a gas-tight crimp. Do not over-crimp or re-crimp a terminal that has already been used.
