Here i showed the forward reverse schematic. Here connect the 3 phase supply to the over load relay same as input to run the motor in forward direction but in case of the reverse contactor we have to reverse one phase for the reversing of direction of motor as shown in the diagram.
A Three Phase Reversing Contactor Wiring Wiring Diagram
Forward reverse contactor wiring diagram. In the above one phase motor wiring i first connect a 2 pole circuit breaker and after that i connect the supply to motor starter and then i do cont actor coil wiring with normally close push button switch and normally open push button switch and in last i do connection between capacitor. Forward reverse three phase motor wiring diagram electrical info pics. 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. Circuitry layouts are made up. There are stop forward and reverse buttons two low current double pole double throw relays for the control circuit thin wire lines and the power circuit thick wire lines which uses.
