Beautiful Forward Reverse Contactor Wiring Diagram

Hello dosto aaj hum sikhen ge k 3 phase motor k liy reverse forward starter control wiring kaise ki jati hy.

Forward reverse contactor wiring diagram. L2 wire connected to the both contactors 2nd terminal. To interconnect the motor circuit in such a way in which the second motor will not start until the first one run likewise the third one motor will not run unless the second one run and so on. Here i had shown that both contactors are 220 vac.

In this example run winding lead t1 will always be connected to l1 and t4 will always be connected to l2. This kind of motor circuit connection is called interlocking. Here the l1 is connecting to the both contactors first terminal.

Here i showed the forward reverse schematic. From the forward push button switch the touch current supply goes to 2nd contactor nc auxiliary contacts and from the auxiliary contacts the wire goes to the first magnetic contactor no auxiliary contacts terminal and coil a2 terminal as shown in the above forward reverse motor control diagram. Within the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb breaker molded case circuit breaker.

And from the mccb breaker i connect the availability to both magnetic contactors. And connect to both magnetic contactors a1 a1 terminals. Signs that stand for the components.

From the 2nd thermal overload relay normal close contacts the supply goes to both contactors coil contacts terminals. This means that the contactors also required the neutral wire. When the forward contacts f close l1 l2 and l3 are con nected to t1 t2 and t3 just as they would be on a non reversing starter.

When the reverse contacts r close the motor is connected l1 to t3 l2 to t2 and l3 to t1. In the above 3 phase motor forward reverse wiring diagram. A schematic diagram of a forward reverse control for a single phase split phase motor is shown in figure 29 13.
