Thomas Betts ADR60-21 Rectangle Ring Terminal 2 Awg

Product Description

The THOMAS BETTS ADR60-21 is a non-insulated rectangle ring terminal designed for compression connections on 2 AWG aluminum conductors. It accepts a 1/2 inch stud and features a titanium nitride (TiN) contact plating over an aluminum contact surface, which helps resist corrosion and maintains conductivity at the termination point. The terminal measures 3-3/16 inches in overall length and 2-13/32 inches in ring width, with a 7/16 inch contact thickness. Electricians and maintenance technicians use this terminal where a secure, mechanical compression lug is required on larger-gauge aluminum feeders.

This terminal is suited for use in electrical distribution, feeder connections, and panel terminations where 2 AWG aluminum wire is routed to bus bars or equipment lugs with 1/2 inch stud hardware. Its non-insulated construction makes it appropriate for applications where the termination point is housed inside an enclosure or where sleeve insulation is applied separately after crimping. It is commonly installed in commercial and industrial electrical systems as well as residential service equipment.

Key Features

• Compression connection type for a reliable mechanical crimp on 2 AWG aluminum wire
• Non-insulated design allows post-crimp sleeving or use in protected enclosures
• Aluminum contact with TiN (titanium nitride) plating for corrosion resistance
• 1/2 inch stud size accommodates standard bus bar and equipment lug hardware
• CSA Certified and UL Listed under UL File E9809; RoHS Compliant

Compatibility

Designed as an OEM-style compression lug for use with 2 AWG aluminum conductors terminating on 1/2 inch stud hardware in electrical panels, switchgear, and distribution equipment.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC). De-energize and lock out the circuit before crimping or torquing any terminal. Use a calibrated compression tool rated for the terminal size and wire gauge to achieve a proper mechanical connection. Inspect the crimped barrel for deformation or cracking before completing the installation.
