Power Circuit of Star Delta Starter.

The main circuit breaker serves as the main power supply switch that supplies electricity to the power circuit.

The main contactor connects the reference source voltage R, Y, B to the primary terminal of the motor U V W1. In operation, the Main Contactor (KM3) and the . Due to the low cost and high availability of these electromechanical devices, the star - delta connection method is still, by far, the most widely used electrical control in industrial applications for reducing the start-up current of three-phase induction motors.

Lets Go Now… Abbreviations: R , Y, B = Re Yellow, Blue ( Phase Lines) C. Control circuit devices for star - delta starting.

Wiring diagrams show the conductive connections between electrical apparatus. CONTROL SCHEMATIC DIAGRAM OF FASD STARTER (OPEN TRANSITION) WITH STAR - DELTA TIMER. Why star delta become common starter of motor control? But this starter also tricky for beginner electrician and who . Thermal overload relay: A thermal over-load relay is likewise consolidated into star - delta control circuit to ensure the motor from intemperate heat which might expedite motor finding fire or wearing out. Applying power to the control circuit starts the motor, removing the control voltage stops it.

From this triangle diagram ,we can determine the correct phase,cable termination for right terminal and the rotation. As we know,the star delta stater is so tricky if we not fully understand the concept and their method. Thermal overload relay (ampere rating depends on motor capacity) - piece 10) 4VAC induction motor (motor capacity depends on application) - unit.
