Thomas Betts RA18-250A Female Wire Disconnect 22-18 Awg

Product Description

The THOMAS BETTS RA18-250A is a fully insulated female wire disconnect terminal designed for quick-connect and quick-disconnect wiring applications. The nylon insulation sleeve covers the full crimp barrel, protecting the connection from accidental contact and environmental exposure. Rated for 22-18 AWG wire, the terminal accepts a 1/4 inch tab width and is suitable for use in control wiring, appliance wiring, and low-voltage circuit terminations. The red nylon insulation identifies the 22-18 AWG wire range at a glance, keeping wire gauge identification consistent across an installation panel or harness.

This terminal is used across residential and light commercial applications wherever a secure, removable wire-to-tab connection is needed. Common install scenarios include HVAC control boards, appliance wiring harnesses, electrical panels, and motor control circuits. The fully insulated nylon body suits environments where bare terminal exposure must be minimized. Each package contains 50 terminals, making this well suited for service stock, panel shops, or technicians completing multi-connection control board replacements.

Installation Notes

Installation is performed by licensed electricians or qualified HVAC technicians. Always de-energize the circuit and verify absence of voltage before crimping or removing terminals. Use a calibrated ratcheting crimping tool sized for the 22-18 AWG range to ensure a full, gas-tight crimp. Follow NEC requirements for wire gauge, overcurrent protection, and insulation ratings applicable to the circuit being terminated.
