Thomas Betts 18RA-251T Male Wire Disconnect 22-18 Awg

Product Description

The THOMAS BETTS 18RA-251T is a fully insulated male wire disconnect terminal designed for secure, push-on electrical connections in control wiring, appliance wiring, and panel assembly applications. The terminal accepts 22 to 18 AWG wire and features a 0.25 inch tab width for standard quick-disconnect receptacles. The nylon insulation is rated UL 94 V-0 for flame resistance and is colored red for easy AWG range identification at a glance. These disconnects are commonly installed by electricians, HVAC technicians, and appliance service professionals where reliable, vibration-resistant connections are required without soldering.

This terminal is suited for residential and light commercial wiring tasks including HVAC control circuit connections, appliance harness terminations, and low-voltage panel wiring. The 0.25 inch male tab mates with standard female quick-disconnect receptacles. The red nylon insulation sleeve provides full coverage over the barrel and wire entry point, protecting against accidental contact and short circuits. Sold in a package quantity of 50, this part suits service technicians stocking field kits as well as shop assemblers working in volume.

Installation Notes

Installation is performed by licensed electricians or qualified service technicians. Always de-energize the circuit and verify absence of voltage before terminating or removing wire disconnect terminals. Use a ratcheting crimp tool rated for insulated terminals in the 22 to 18 AWG range to achieve a proper crimp without damaging the nylon sleeve. Do not over-crimp, as this can fracture the insulation and compromise the UL 94 V-0 flame-resistance rating.
