S701 soft starter

The S701 line of soft-start controllers is specifically designed to be a low-cost option for soft-starting small (15 hp and below) three-phase motors. The S701 controls current on two of three motor phases to control the torque being applied to the motor, allowing for smooth starting. It is designed to be used with a manual motor starter or a full voltage starter and provides the necessary overload protection as well as line isolation for the motor.
