Star-Delta motor starter LT3-D 32A/400V 50Hz Without box

A Star-Delta starter, is a type of motor starter used to reduce the starting current and torque of three-phase induction motors. It is commonly used for larger motors that require a lower starting current to minimize voltage drops and mechanical stress during motor startup. The Star-Delta starter employs a specific switching arrangement to achieve this. The Star-Delta starter offers a compromise between the high starting current of the DOL starter and the precise control of more advanced starters like soft starters and variable frequency drives VFDs. It is commonly used in applications where the motor needs to start under reduced current conditions but can operate efficiently at full voltage once it reaches a certain speed.
