Dold BA9026 3AC50/60HZ 200-460V 5,5KW | Softstarter, Part N: 0058979

Softstarts are electronic devices designed to enable 1-phase or 3-phase induction motors to start smoothly. The BA 9026 slowly ramps up the current on three phases, therefore allowing the motor torque to build up slowly. This reduces the mechanical stress or the machine and prevents damage to conveyed material. When the motor is up to full speed the semiconductors in BA 9026 are bridged to prevent internal power losses and heat build up to addition BA 9026 allows a softstop function prolonging the stop time of the motor preventing high counter torques from abruptly stopping the motor.
