The Thomas & Betts RB717 Sta-Kon wire termination insulation represents a significant advancement in electrical connection technology. Developed over 70 years ago, these terminals prioritize performance and reliability. Key features include a long barrel design for reduced electrical resistance and increased pullout strength, deep internal serrations that allow wire strands to cold flow for a secure connection, and a funneled barrel entry for faster and easier wire insertion. The brazed or overlapped seam ensures the terminal is a single, solid piece, preventing wire strand loss and electrical failure. Selective annealing provides the barrel with the flexibility needed for easy crimping while maintaining a strong tongue for repeated bolt tightening. These terminals are ideal for applications requiring robust and dependable electrical connections, minimizing rework and downtime.
