How To Connect A 3 Phase Contactor

By | February 10, 2023



Connecting a 3 phase contactor can be a daunting task for the uninitiated, but it doesn't have to be. With a few simple steps, you can ensure that your 3 phase contactor is properly connected and ready for use.

The first step in connecting a 3 phase contactor is to connect the neutral and ground wires. The neutral wire should be connected to the same terminal as the ground wire, while the live wires should be connected to the separate terminals. It is important to make sure that the polarity of the wiring is correct; otherwise, the contactor won't function properly. Once the wiring is completed, you can then begin to install the contactor into its housing.

Once the contactor is secured in its housing, the next step is to connect the starter relay. This relay is responsible for controlling the power flow to the contactor, so it is important to make sure that it is correctly connected. To do this, you will need to connect the neutral wire and the ground wire to two separate terminals on the starter relay. Once these connections are complete, you can then attach the leads from the contactor's coil to the remaining terminals on the starter relay. Finally, you will need to connect the control wires from the contactor to the corresponding terminals on the starter relay.

By following these simple steps, you can easily connect a 3 phase contactor and get it ready for operation. While the process may seem daunting at first, once you understand the basics, connecting a 3 phase contactor becomes much simpler.
