Star Delta Starter Panel:
A Star Delta Starter Panel is an electrical control panel used to start and protect three-phase induction motors by reducing the high inrush current during motor startup. The motor initially starts in star (Y) connection, which lowers the starting current and torque. After the motor reaches a predefined speed, the panel automatically switches the motor to delta () connection for normal operation at full voltage.

The panel typically includes contactors, a timer, overload relay, MCB/MCCB, and control circuitry. It helps minimize voltage dips, reduces mechanical stress on the motor and driven equipment, and improves overall system reliability. Star Delta Starter Panels are widely used in pumps, compressors, conveyors, and industrial machinery.
