Allen Bradley STC Starting Torque Controllers – Find comprehensive resources for Allen Bradley STC softstarter, including product catalogs, manuals, price list, programming guides, fault, alarm, warnings & software support. Get expert assistance for troubleshooting and optimization.
Allen-Bradley STC (Starting Torque Controller) is a cost-effective way to soft-start low horsepower single- and three-phase induction motors. They reduce mechanical and electrical stress on motor circuits and systems by limiting voltage during startup.
STC Starting Torque Controllers provide a cost-effective, soft-starting solution for low horsepower single- and three-phase squirrel cage induction motors. Our starting torque controllers help reduce mechanical and electrical stress on motor circuits and systems by limiting voltage at startup. 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.

- Duration of Ramp (0.5…5 sec)
- Ideal for adding on to existing direct-on-line starters
- Offers energy savings
- Less wear and tear on mechanical systems
- Offers ideal applications such as
- Basic material handling
- Fans
- Pumps
- Single-phase reduced-voltage starting applications
Reduce Mechanical and Electrical Stress :
The Starting Torque Controller (STC) provides a cost-effective basic soft- starting solution for low horsepower single and three phase squirrel cage induction motors. Models are available to work with single-phase motors, as well as one or two control phase versions for three-phase motors.
Starting Torque Controllers help reduce mechanical and electrical stress on motor circuits and systems by limiting the torque surge at start-up. Starting torque controllers are ideal for adding on to existing across the line starters. They allow for adjustable initial torque and ramp time. Ideal applications include basic material handling, fans, pumps, and single phase reduced voltage starting applications.
