Allen-Bradley STC™ 154-SP1C12NAD Starting Torque Control With Captivated Washer, 100 to 240 VAC Coil, 1 Pole, Open Enclosure

Our bulletin 154 STC™ starting torque controllers provide a cost effective, soft-starting solution for low horsepower single and 3-phase squirrel cage induction motors. Our starting torque controllers help reduce mechanical and electrical stress on motor circuits and systems by limiting voltage at start-up. This avoids the over torque and over current conditions that happen when across the line circuits are completed, like when a basic motor control contactor closes.
