3994-4000 



Air-Cooled Regulating Starters, for three-phase motors with slip-ring rotor. The 

 regulators enable the motor to run at reduced speed for any length of time. They will 

 reduce the speed to extent listed when the motor is exerting not less than f normal torque ; 

 when the load is smaller than this, the range of speed regulation is proportionally smaller. 

 The speed varies with the load, and the tendency of the speed to fluctuate with the load 

 becomes more and more pronounced as the speed is diminished.
