Thomas & Betts 18RA-6 Vinyl-Insulated Ring Terminal

Description:

The Thomas & Betts Sta-Kon® 18RA-6 Vinyl-Insulated Ring Terminal is used to terminate 22–16 AWG copper conductors to #6 stud connections in low-voltage electrical and control systems. Commonly installed in industrial control panels, commercial electrical equipment, HVAC systems, machinery, automotive wiring, and OEM assemblies, this red vinyl-insulated ring terminal features a brazed seam barrel and electro tin-plated copper construction for secure, corrosion-resistant electrical connections. Electricians, maintenance technicians, and panel builders use this terminal for new installations, repairs, retrofits, and replacement of crimp-style wire terminations.

Applications:

The Thomas & Betts Sta-Kon 18RA-6 is designed to provide dependable crimp terminations for 22–16 AWG copper conductors on #6 screw or stud terminals. Its closed-ring design prevents accidental disconnection, while the long vinyl insulation sleeve provides additional strain relief and insulation protection. It is ideal for terminal blocks, relays, contactors, circuit breakers, industrial control panels, HVAC equipment, automation systems, marine electrical installations, and general-purpose commercial wiring.
