Thomas Betts TNF18-250FD-XV Female Disconnect 22-16 Awg

Product Description

The THOMAS BETTS TNF18-250FD-XV is a fully insulated female disconnect terminal designed for fast, reliable wire termination in electrical and control wiring applications. Covered in a red nylon insulating sleeve, this disconnect accepts 22-16 AWG wire and features a 1/4 inch tab width for mating with standard male quick-disconnect tabs. The nylon insulation meets UL 94 V-2 flame-rating requirements and carries CSA certification, UL listing under File E9809, and RoHS compliance. Electricians and control panel technicians use this terminal where color-coded, insulated connections are required for low-voltage or signal circuits.

This female disconnect terminal is suited for residential, commercial, and light industrial wiring where push-on connections are preferred over screw terminations. Common applications include HVAC control wiring, appliance harnesses, panel subassemblies, and equipment repair. The 1/4 inch tab width is a widely used standard dimension compatible with many male disconnect tabs found on relays, switches, and terminal blocks. Each package contains 75 pieces, making it practical for service kits or production runs requiring a consistent supply of color-coded terminals.

Key Features

• Fully insulated red nylon sleeve for visual identification and protection against accidental contact
• Accepts 22-16 AWG wire — covers light control wire through standard branch-circuit wire gauges
• 1/4 inch tab width mates with standard quick-disconnect male tabs on relays, switches, and terminals
• UL Listed (File E9809) and CSA Certified for use in compliant electrical installations
• UL 94 V-2 flame-rated nylon insulation material
• RoHS compliant — suitable for installations with hazardous-substance restrictions

Compatibility

Designed as an OEM-style replacement or new-installation female disconnect terminal for 1/4 inch male quick-disconnect tabs across residential, commercial, and light industrial electrical applications where 22-16 AWG wire is used.

Installation Notes

Installation is performed by licensed electricians or qualified technicians following local electrical codes and NEC guidelines. De-energize the circuit completely before crimping or connecting terminals. Use a calibrated ratcheting crimp tool sized for 22-16 AWG insulated terminals to achieve a secure mechanical and electrical connection. Do not over-crimp or use pliers in place of a proper crimp tool, as this can damage the nylon insulation and weaken the wire-to-terminal joint.
