Features
- Range of performance: 4.0 - 9.0 kW - higher capacities on request
- Initial current limitation during the start of asynchronous motors
- Start-up current reduction to one third of the value when starting directly considering the run up time
- Several implementations available
- Manually actuated
These star-delta starters are provided with an overload protection, e.g. 7.5 - 11 A in line which results in a rated motor current of 13 - 19 A. Other overload protections are available on request.

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.
The most simple implementation of a star-delta-changeover switching is realised by a cam switch. The changeover switching from 0 to star and delta is done manually by the operator. To avoid undesired voltage peaks, at least 80% of the rated speed has to be achieved when switching from star to delta. Connecting a motor attention should be paid to the rated motor voltage.
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.
