The soft starters of SSB-21 series are designed for effective start, protection and stop of three-phase induction motors. Their application is urgent in numerous branches of industry: pumps, fans, compressors and other mechanisms.
The SSB-21 soft starter is a cost-effective solution enabling dispose of the following:
- voltage sags and current leaps at direct start of the induction motor;
- hydraulic shocks and pressure jumps in pipelines at start and stop of the pumps;
- mechanical overloads which lead to the necessity of frequent maintenance and repair.
