Star Delta Control Panel
Start-Delta starters are the most common starters used widely to start AC motors. In these starters the starting current is controlled by applying reduced voltage, which is achieved by connecting motor winding in “Star” mode. Theoretically the current is reduced by a factor of 1 / 3 times and once the motor attains it's normal running stage, full voltage is applied to the motor by changing the connection to “Delta” mode and remains in the same stage till the motor is stopped.
Protection:
Over Voltage
Under Voltage
Overload
Short Circuit
No Load
Dry running
Phase Failure
Phase reversal (Optional)

local / remote operation & customized features against requirement
Advantages:
The operation of the star-delta method is simple and rugged
It is relatively cheap compared to other reduced voltage methods.
Good Torque/Current Performance.
It draws 2 times starting current of the full load ampere of the
motor connected
