STC starting torque controllers
Art. STC
STC starting torque controllers are a cost-effective solution for soft starting low-power single- and three-phase squirrel-cage induction motors. These starting torque controllers help reduce the mechanical and electrical stress on the motor circuits and systems by limiting the starting voltage. This avoids overtorque and overcurrent conditions that occur when short-circuiting circuits across the line, such as when the motor's main control contactor closes.
