The Allen-Bradley® Starting Torque Controller (STC) is designed for low horsepower single and three-phase squirrel cage induction motors. It is designed to help reduce system shock (electrical and mechanical) typically seen when directly starting on line voltage. This provides a smoother start and helps decrease downtime due to shock and vibration related problems. Typical applications include fans, material handling, pumps, palletizers, car washes and reduced voltage start single-phase applications.
