Thomas Betts TNF10-250FD-XV Female Disconnect 12-10 Awg

Product Description

The THOMAS BETTS TNF10-250FD-XV is a fully insulated female disconnect connector designed for reliable quick-connect terminations in electrical wiring applications. Built with a nylon insulator in a yellow color coding, this connector accepts 12-10 AWG wire and features a 1/4 inch tab width for compatibility with standard male disconnect terminals. The nylon insulation meets UL 94 V-2 flame ratings and carries both UL Listing under File E9809 and CSA Certification, making it suitable for professional electrical installations where listed components are required. RoHS compliance supports use in environmentally regulated assemblies. Each package contains 75 connectors.

This connector is used in residential and light commercial electrical, HVAC control wiring, appliance wiring, and automotive or equipment harness work where a secure, insulated push-on female disconnect is needed. Electricians, HVAC technicians, and equipment assemblers use these terminals to create serviceable connections that can be disconnected and reconnected without special tools. The yellow insulation color indicates the 12-10 AWG wire range, following standard color-coding convention for quick identification during installation and service.

Key Features

• Fully insulated nylon construction rated UL 94 V-2 for flame resistance
• Accepts 12-10 AWG wire for medium-duty current-carrying applications
• 1/4 inch tab width fits standard male quick-disconnect terminals
• Yellow insulation provides visual wire-gauge identification per industry convention
• UL Listed (File E9809) and CSA Certified for use in listed assemblies
• RoHS compliant for use in environmentally regulated equipment

Compatibility

Designed as an OEM-style replacement and general-purpose female disconnect terminal compatible with standard 1/4 inch male quick-disconnect tab terminals used in residential and commercial electrical, HVAC, and appliance wiring applications.

Installation Notes

Installation is typically performed by licensed electricians or HVAC technicians. De-energize the circuit and verify absence of voltage with a meter before making or breaking any connections. Use a calibrated ratcheting crimp tool rated for insulated terminals to achieve a proper crimp on 12-10 AWG conductors — hand-squeezing or improper tooling can result in a high-resistance or pull-out failure. Follow NEC requirements for conductor sizing, termination methods, and circuit protection when incorporating these connectors into listed assemblies.
