Thomas Betts A18-10 D-shaped Ring Terminal 22-16 Awg

Product Description

The THOMAS BETTS A18-10 is a non-insulated, D-shaped ring terminal designed for crimp connections on 22 to 16 AWG copper wire. The terminal body is copper with a TiN (titanium nitride) contact plating, which improves corrosion resistance and contact surface durability. At 0.75 inches overall length and 0.31 inches ring width, it is sized for a No. 10 stud. This terminal is sold in a package of 100 units, making it a practical stock item for electricians and panel wiring techs who work with light-gauge control wiring, low-voltage circuits, and instrumentation terminations.

This ring terminal is suited for residential and commercial electrical applications where a secure, permanent crimp termination is required at a No. 10 screw or stud. Typical uses include control panel wiring, HVAC low-voltage control circuits, appliance wiring, and general electrical enclosure terminations. The non-insulated barrel leaves the connection visible for inspection, which is preferred in applications where post-crimp verification or heat-shrink sleeve over-application is part of the workflow.

Key Features

• D-shaped ring design fits No. 10 studs and provides positive retention against pull-out
• Accepts 22 to 16 AWG wire with a crimp connection — no soldering required
• Copper contact with TiN plating for improved corrosion resistance and conductivity
• Non-insulated barrel allows visual inspection of the crimped wire after termination
• Meets UL 486A, UL 486B, CSA 22.2, and RoHS compliance requirements
• Packaged in quantities of 100, minimizing reorder frequency on active jobs

Compatibility

Designed for crimp termination onto 22 to 16 AWG copper conductors at No. 10 stud sizes, consistent with general-purpose electrical panel, control board, and enclosure wiring applications.

Installation Notes

Installation is performed by licensed electricians or qualified technicians using a calibrated ratcheting crimp tool rated for the applicable AWG range. De-energize and lock out the circuit before making or breaking any termination. Verify wire strip length matches the barrel depth before crimping. Connections must comply with applicable NEC requirements for the circuit type and enclosure rating.
