Overview
The ABB Thomas & Betts Sta-Kon C221M is a non-insulated locking fork terminal engineered for secure, vibration-resistant connections in panel wiring, control cabinets, and electrical assemblies. The locking-style barrel grips the stud and prevents the terminal from backing off under load, making it ideal for high-vibration environments. Manufactured from electrolytic copper with a tin plating for corrosion resistance, each terminal accepts #12–#10 AWG wire and fits #8 hardware. Supplied on Mylar tape in a 500-pack for use with automatic and semi-automatic termination machines.
