Dold BL9028.03 3AC200-480V UH=DC24V 11kW Safety relay, Part N: 0068352

Softstarters are electronic devices designed to enable 1-phase or 3-phase induction motors to start smoothly. By means of internal current monitoring we realise different protective functions, when stalling the motor or during heavy duty starting. The semiconductors are bridged after softstart by relay contacts. This reduces power dissipation and heating. The device parameters are adjusted using potentiometers. LEDs indicate the status of the device.
