Sta-Kon

Sta-Kon is a brand of crimp wire terminals and electrical connectors in ABB's Thomas and Betts product portfolio. Thomas and Betts developed the first tool-applied solderless terminals more than 70 years ago. ABB acquired Thomas and Betts in 2012. Sta-Kon terminals are used in HVAC control wiring, electrical panel assembly, building controls, and industrial wiring applications.

Product Lines

• Ring Terminals (R series): Vinyl-insulated and non-insulated copper; stud sizes 8, 10, 1/4", 5/16", 3/8"; 24 AWG to 0 AWG range
• Fork/Spade Terminals (RA series): Push-on connection; releasable without removing screw; vinyl-insulated
• Butt Splices (C series): Straight-through wire joins; vinyl-insulated and heat-shrinkable versions
• Disconnect terminals for quick-connect/disconnect control and field wiring
• Heat-shrinkable terminals, splices, and disconnects for moisture-exposed applications
• Sta-Kon STAKIT crimp kit: assorted butt splices, ring, fork, disconnect terminals with crimp tool
• Spec-Kon (higher performance) and Shield-Kon (shielded cable) specialty series
• Construction: High-conductivity copper; corrosion-resistant plating; brazed/overlapped seam (2.5x tensile strength vs. butted seam); deep internal serrations; chamfered funneled barrel

Why Electricians and HVAC Technicians Specify Sta-Kon

• 70-plus year history as the dominant solderless terminal brand; universally recognized color coding
• Brazed/overlapped seam: 2.5x tensile strength vs. butted seam reduces vibration failure risk
• Deep internal serrations lower connection resistance and prevent wire pullout under vibration
• Chamfered funneled barrel prevents wire strand hang-up during insertion

How to Choose Sta-Kon Terminals

Match terminal color to wire gauge: red (22-18 AWG), blue (16-14 AWG), yellow (12-10 AWG). Select type: ring terminal for screw terminations; fork for push-on stud connections; butt splice for straight-through joins; disconnect for field-service connections. Match ring hole to stud size. For moisture exposure: specify heat-shrinkable version; activate with heat gun after crimp.

Frequently Asked Questions
