Functional description
Star-delta-starter are used to operate asynchronous motors from 4 kW to avoid excess current during start-up of the motor. Thresholds are usually defined by the electric supply company.
Unlike hand-operated star-delta-starters these starters either have their own logic controller or can be operated manually, so that the starting time can be optimized for every application.
Starting is implemented by means of a contactor controller, a special time relay (KLIBO-Star-Delta-Timer) and an integrated overload relay. High operational reliability is achieved by observing important switching sequences and locking the controls.
The changeover switching time should be set in a way that 80% of nominal speed are achieved when the changeover switching from star to delta takes place. A motor suited for star-delta must have a voltage rating of 380 V / 660 V or delta 380 V. Six external winding terminals are necessary to connect such motors.
Star-delta-starters are used in machine tools, wood processing machines, compressors etc. These starters may be equipped with our new electronic brake controls.
