Star Delta Starter Control Circuit Diagram With Timer

Star delta starter control circuit diagram is today topic. In my last post I share a star delta starter wiring diagram 3 phase motor connection. In this post you will learn complete star delta starter wiring with timer, normally open push button switch and normally close push button switch. For high load 3 phase induction motor we use the star delta starter. which includes 3 magnetic starter, Overload motor protection relay, NO/NC push button switch, On delay 8 pin timer and electric wires.

Star Delta Starter Wiring Diagram 3 phase With Timer

Star delta starter wiring diagram, this post is about the main wiring connection of three phase motor with star delta starter and control wiring diagram of star delta starter. For three phase motor we use the direct online starter but mostly for small three phase motor. But high load 3 phase motor we use the star delta starter for motor controlling. A star delta starter is type of motor starter which run 3 phase motor in star in starting time. And when the motor start, after some time it's run the motor in delta connection.

Star Delta Starter Wiring Diagram 3 Phase

To make a star delta starter you need...

1 MCCB Circuit Breaker
3 magnetic contactors
3 phase motor thermal overload relay / Electronic overload relay OCR
A on daily timer (8 pin timer with 8 pin glass type relay socket/base)
1 Normally close push button switch
1 Normally open push button switch
Electric wires for main motor wiring
Electric wires for controlling wiring

Star Delta Starter Wring For 3 Phase Motor Diagram

Here I shown the complete star delta starter wiring diagram 3 phase. The three phase supply shown with RED, Yellow And Blue Coolers.- All connection with a 3 phase induction motor.

The above is a star delta starter wiring diagram 3 phase motor for main wiring. Now let's see the star delta starter control circuit diagram with timer, NC/NO push button switches.

Star delta starter control circuit diagram

In the above star delta starter control circuit wiring diagram with timer and normally close push button/normally open push button switch. In control wiring diagram all magnetic contactors coils are rated 220 VAC. A 8 pin timer are used. The on delay timer diagram is also shown in the diagram.

How On Delay Timer Works | Star Delta Timer Diagram

This post is about "how on delay timer works" or how star delta timer works with diagram explanation. In the post you will see a complete wiring diagram of star delta timer. In the diagram 2 light bulbs are wired with 8 pin timer.
In the on delay timer working diagram. 3 MCB circuit breakers are wired for controlling the supply. A 8 pin timer wired. On light bulb will ON when timer is not operated. When the supply provided to timer the light bulb will be off.
The second light bulb will be ON when the timer complete the time. The on delay timer wiring diagram shown below.

8 Pin Timer Wiring Diagram

This post is about the 8 pin timer wiring diagram. Mostly we use the 8 pin timer in ATS System (automatic transfer switch), Star delta starter and many other places where we needed the timing in circuit. The below diagram is on delay timer wiring diagram. Note that to wire a 8 pin timer we use the 8 pin relay socket.

Air Room Water Cooler Wiring Diagram

This post is about the air room cooler wiring diagram. In the diagram i shown the complete Air water cooler wiring diagram. In the diagram you will see a fan motor two speed (low and high). A water pump motor connection and swing motor.

Air Room Cooler Wiring Diagram

In the below wiring diagram you will see the complete wiring. The main supply shown with red, black and green colors. The red color for Line wire, black color for Neutral wire and green for Earth wire.

In the air water cooler wiring diagram all motor connection shown with capacitor. The two way switches are use for color the all three motors. The fan motor have two speed, low and high which is controlled from first switch.
The second switch control the swing motor. The 3rd switch controlled the water pump motor.
