A Star Delta Panel is a type of electrical panel used to control and protect electric motors. It is designed to ensure the safe and efficient operation of the motor by providing a range of functions, including starting and stopping the motor, protecting it from overload and overcurrent conditions, and adjusting the motor's speed and torque.

The panel typically consists of a contactor, which is an electrical switch that controls the motor's power supply, and an overload relay, which protects the motor from damage due to overcurrent or overload conditions. Other components may include circuit breakers, fuses, and various control devices such as timers, switches, and indicators.
