Soft Starter Device SPTU-D-6-125 UHL4 for Smooth Motor Start Applications

for soft start of synchronous and asynchronous electric motors of medium voltage 3-10 kV with capacity up to 17 MW.
Provides:
smooth increase of motor current up to the value of the initial current limitation, which provides motor starting from the place, thus the possibility of setting the set point of smooth increase of motor current as a function of time (angle of slope of time-current characteristic) is provided;
formation of a preset current limitation with starting current up to 4 Inom dv. when the motor is accelerated to nominal speed;
individual setting of starting characteristic for each motor (up to 10 adjustable sections of current-limiting curve according to TOR or OL).
