Forward reverse contactor wiring diagram. Why 3 phase ac instead of single phase. 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. Within the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb breaker molded case circuit breaker. One of them contactor is forward contactor and other is reverse contactor. Wiring diagram forward reverse contactor best forward reverse wiring single phase motor with capacitor forward and reverse wiring diagram exactly whats wiring diagram. 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.
We use 2 magnetic contactors as forward reverse switch. For three phase motor forward reverse negative feedback circuit. Here i showed the forward reverse schematic. Power wiring of reverse and forwaed motor. Posted by fritz on mar 05 2017. 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.
A wiring diagram is a type of schematic which makes use of abstract photographic symbols to show all the affiliations of components in a system. 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.
